How to Write a Winning Sponsorship Letter (+8 Templates)

You've found a brand that could be a good fit for your event. Now you need to explain why they should spend money with you. A useful sponsorship letter makes that decision easier by connecting a specific audience to something the brand wants, describing a credible offer, and asking for a clear next step.

For an operator running paid events, there's another test. The deal has to improve your event's finances after you pay for everything you've promised. Filling a sponsorship package with extra work to make it look valuable can leave you with less money and a much busier production team.

Start with the commercial fit, then write the letter. Keep the first approach short enough to read in one sitting, support it with evidence you actually have, and save detailed delivery terms for the proposal and agreement. The eight examples below show how that changes across festivals, conferences, fundraisers and other event formats.

Sponsorship measurement is a real concern, but the context matters. Forrester's June 2025 article discusses large-scale sports sponsorships, rather than proving that every local event has access to a growing brand budget. Its discussion is useful when planning what you'll measure. Source: Forrester

What a sponsorship letter needs to achieve

A sponsorship is an exchange. The brand provides money, products or services, and you provide agreed opportunities associated with your event. That might mean a place to demonstrate a product, access to an appropriate professional audience, hospitality for customers, or recognition for supporting a community programme.

The letter introduces that exchange. It doesn't need to contain your entire event history, every package option or the final contract. It needs enough information for the right person to decide whether a conversation is worth having. A local business owner may make that decision themselves. At a larger company, your contact may need to forward the message to a regional marketing manager or someone responsible for partnerships.

Write something that remains clear when forwarded. State the event name, date, location, relevant audience and proposed opportunity in the message itself. If the only useful information is hidden in an attachment, the next person has to do more work before they can assess it.

A donation request follows a different logic. It asks someone to support a cause, and the recipient may not expect a commercial benefit. Don't describe every sponsorship as a donation or promise tax treatment to make the offer more appealing. The substance of the arrangement matters.

You also need to distinguish what you can deliver from what you hope happens afterwards. You can commit to an agreed booth location, a published email inclusion and a staffed demonstration area. You can't control whether someone buys the sponsor's product next month. Nielsen's sponsorship measurement approach considers several forms of impact, which is a useful reminder to define the result before choosing the measure. Learn more

Before writing, decide which sponsor is worth approaching

Start with an audience the brand actually wants

The strongest fit is usually more specific than a shared interest in music, food or entrepreneurship. A beverage brand launching in your city may value local sampling. An equipment supplier may want a demonstration with working professionals. A hotel may want room bookings during an event weekend. Those are different offers, even if all three companies could afford the same package.

Read the company's own website, current announcements and public campaign material. Look for a reason this event would matter now. Then check your evidence. If your audience information comes from last year's ticket buyers, say so. If it comes from a voluntary survey, keep the sample size and question available. Don't describe every attendee as a buyer with purchasing authority because a few survey respondents had senior job titles.

For a first event, use what you can show today. That might include paid bookings so far, the confirmed venue, a published programme, participating exhibitors and the experience of the production team. Label forecast attendance clearly and explain the basis for it. A smaller verified audience can be a better starting point than an ambitious prediction with no explanation.

Find the person and the budget

A brand can be a good audience fit and still be a poor prospect for this edition. Its annual budget may already be allocated. The local manager may control product samples but have no cash sponsorship budget. A distributor may handle event partnerships in your region, rather than the company whose logo is on the product.

Before building a custom proposal, find out who makes the decision, what sort of support they can consider, and when they can approve it. A short routing message can help: "Who handles local event partnerships for [region]? We're producing [event] on [date] and have a relevant sampling opportunity." That asks for information without pretending the recipient has already shown interest.

If the brand offers stock when you need money for a venue deposit, the mismatch won't disappear with a better letter. Treat product and cash as different forms of support. Product is useful when it replaces something you were going to buy or improves an experience you can afford to deliver. It doesn't pay a supplier who requires a bank transfer.

Check whether you can honour the offer

Read your venue, supplier and existing sponsor agreements before offering category exclusivity. The venue may already have an exclusive drinks contract. Your caterer may control the concession area. An artist agreement may restrict sponsor references in performance footage. You need the rights before you sell them.

Check practical restrictions too. A tasting station needs a suitable location and an agreed approach to staffing, power, waste and any required permissions. A sponsored session needs space in the programme and editorial approval. If the operations lead can't explain how the activation will work, keep it out of the first promise until you've resolved the details.

This screening also protects your time. Build a short list of brands with a credible audience match, an available opportunity and a workable decision window. Researching those companies properly is more useful than sending the same message to a long list of unrelated contacts.

What to include in your sponsorship letter

Keep the letter focused on the recipient's decision. A formal letter can use your organisation's address and the date at the top. An email usually needs a clear subject, a direct opening and a complete signature. Neither format needs several paragraphs of company background before the reader knows what you're offering.

A subject line that describes the opportunity

Use the event name and the relevant opportunity. "Sampling partnership for [event], [city], [date]" tells the recipient more than "Exciting collaboration opportunity". If you've already spoken, make the connection clear: "Following our call: [event] sponsorship proposal". Don't imply there's an existing conversation when there isn't one.

An opening with event details and audience fit

Introduce yourself, name the event and explain the connection to the brand. For example: "We're producing [ticketed food festival] at [venue] on [date]. Your new [product] looks relevant to our [verified audience description], and we're looking for a partner for the tasting area."

Use evidence only when it helps the recipient judge fit. An attendance figure needs a clear meaning. Unique people, tickets issued and visits across several days aren't interchangeable. If a sponsor could reasonably interpret the number differently, explain it before it becomes a disagreement.

A proposed benefit and a price indication

Choose the opportunity that best matches the brand's goal. If the sponsor wants product trial, explain the sampling experience. If it wants customer hospitality, describe the guest experience and what the package includes. A long list of logos, posts and mentions can obscure the reason to buy.

You can include a package price or a sensible starting range when you've costed the offer. It helps the recipient decide whether to continue. Don't invent a low opening price and then reveal essential production charges later. If the sponsor needs to supply staff, products or a build, say so early.

Offer optional detail separately. A concise first email can link to a package page or propose a call. A proposal requested after a discussion should include the agreed scope and price. The stage of the conversation determines how much detail the reader needs.

Evidence, measurement and a next step

Choose one useful proof point, such as verified previous attendance, relevant buyer information or a photograph of a comparable space you've actually delivered. Explain what you'll report for this opportunity. You might offer distribution counts for samples, attendance at a sponsored session or aggregate engagement with an agreed link. Each measure should answer the sponsor's stated question.

Finish with a specific, easy response. "Is local product sampling part of your plan for [period]? If so, could we discuss the [event] opportunity next week?" is a reasonable first ask. If they've already requested a proposal, ask them to confirm the scope or raise any questions before the production deadline.

Write the first version, then cut what doesn't help

Start by writing the offer in ordinary words before formatting the letter. Explain who will attend, why the sponsor should care, what you're offering, what it costs and what happens next. If you can't explain that without phrases like "unparalleled exposure" or "powerful synergy", the offer probably needs more work.

Next, check each audience claim against the record behind it. Keep past results, current bookings and forecasts separate. If you write "last edition's attendees were mostly local", make sure you know how you established that. A postal address field, a survey response and a social account's follower location answer different questions.

Choose measurement that fits the sponsor's objective rather than promising every available metric. There are established approaches to sponsorship measurement, but you don't need to imply a small event can reproduce a major sports property's research programme. Use them to clarify what you can credibly report. Reference: Nielsen Sports ROSI

Then read the letter from the recipient's side. Can they tell whether the event date fits, whether the audience is relevant and whether the offer is within reach? Remove the biography, broad market commentary and repeated claims that delay those answers. A short letter can still contain a developed explanation of why the partnership makes sense.

Finally, check names, dates, location, pricing, contact information and links. Send yourself a copy and open it on a phone. If your colleague can't explain the proposed partnership after reading it once, ask which detail was missing and revise that part.

Eight sponsorship letter examples you can adapt

The following examples are fictional teaching templates, including the event and company names. All bracketed audience figures, prices, dates and results must be replaced with your own verified information. Nothing in these examples is a real event result, a recommended market price or a promise of sponsor performance.

The downloadable Word files are editable starting points. Check them independently before sending, especially any sample numbers, old dates, audience descriptions and benefits. The advice beside each example explains the decisions you need to make for that format.

1. Sponsorship letter for a festival

A festival sponsor may need room for a physical activation, so establish the experience before selling exposure. Check the site's usable space and which party pays for the build, staff and consumables. An appealing tasting idea becomes expensive if the brand assumes your team will supply everything.

Subject: Sampling partnership for [Sunset Sounds Festival] in [city]

Hi [name],

I'm [your name] from [organising business]. We're producing [Sunset Sounds Festival] at [venue] on [dates]. Our previous edition welcomed [verified unique attendance], and [relevant audience evidence] suggests a useful fit for your [product or campaign].

We're looking for a partner for the [named area]. The proposed package is [price] and includes an agreed sampling space, [specific event placement] and [defined promotional inclusion]. You would provide the products and sampling team; we would provide [confirmed site services].

We can share the site plan and previous attendance evidence. For the activation report, we propose recording [measure the team can actually collect], alongside photographs of the agreed placements. We'll confirm the reporting method with you before signing.

Would this fit your plans for [market or period]? If so, are you available [time option] or [time option] to discuss the space and production requirements?

Thanks,

[Your name], [role] | [business] | [phone] | [event page]

Use this version when the brand has a product attendees can reasonably try at your event. If the sponsor mainly wants hospitality, rewrite the central offer around guests, access and service instead. Don't keep sampling benefits simply because they appear in the template.

2. Sponsorship letter for a charity fundraiser

For a ticketed fundraiser, separate the charitable purpose from the benefits offered to the sponsor. Describe the impact you can substantiate, and avoid treating every dollar received as direct programme funding when event costs also need paying.

Subject: [Harvest Gala] partnership supporting [programme]

Hi [name],

On [date], [organising charity] is hosting [Harvest Gala] at [venue] to raise funds for [specific programme]. Last year's programme delivered [verified service result, with period]. This edition's fundraising target is [target], subject to final event costs.

Your support for [verified relevant activity] makes this worth exploring. We're seeking a [named partnership] at [price], with acknowledgement in the event programme, [defined recognition] and [specified hospitality, if appropriate]. We can explain how event proceeds support the programme and provide our most recent impact report.

The attached proposal separates the event benefits from the charitable purpose so your team can review the arrangement accurately. We would confirm any proposed promotional activity and the treatment of the package with our advisers before agreement.

Would you be open to discussing whether this fits your community partnership budget? I can share the programme detail and proposed recognition before a call.

Thank you,

[Your name], [role] | [charity] | [contact details]

In the US, the IRS explains that advertising and substantial return benefits can affect whether a payment qualifies as sponsorship for unrelated business income purposes. Renaming a sales pitch an acknowledgement doesn't settle that question. Review the actual package against the IRS sponsorship guidance.

3. Sponsorship letter for a sports team or tournament

A tournament audience can include participants, spectators and accompanying families. Describe those groups accurately. Team entries aren't a count of unique spectators, and total attendance across a weekend can include repeat visits. The sponsor needs to understand the audience it can actually reach.

Subject: [Spring Slam] tournament partnership in [city]

Hi [name],

We're organising [Spring Slam] at [venue] on [dates], with [confirmed team entries] currently booked. Our previous edition recorded [verified attendance measure], and we can share how that was counted.

We're approaching [company] about a [hydration, equipment or other relevant] partnership because [specific audience connection]. The proposed package includes [defined location], [approved branding] and [relevant product experience], priced at [price].

Before confirming, we'd agree the product quantities, delivery schedule, staffing and any venue restrictions. For events involving young people, the activation would follow our safeguarding arrangements and the venue's rules. We wouldn't include access to children's contact details in the package.

Could we discuss whether this fits your local partnership plans? I can send the tournament schedule and a simple outline of the space and responsibilities.

Thanks,

[Your name], Tournament Director | [business] | [contact details]

Check any governing-body, venue or existing supplier restrictions before promising category exclusivity. If the sponsor supplies equipment, agree whether it is a loan or a donation, who handles installation and who is responsible for collection. Those details change the value of the offer to you.

4. Sponsorship letter for a tech conference

A conference sponsor often needs a relevant professional audience rather than the largest attendance number. A useful letter explains which roles attend and how you know. If you've surveyed buyers about budget responsibility, keep the result specific to respondents instead of assigning it to the entire audience.

Subject: [DataForward] partnership for your [relevant product] team

Hi [name],

[DataForward] takes place at [venue] on [dates], with sessions for [specific professional audience]. Our previous edition's [registration or survey evidence] shows [relevant verified audience detail], which looks relevant to your [product or campaign].

We'd like to discuss a [track, demonstration or roundtable] partnership at [price]. It would include [defined session or space], [specific promotional inclusion] and a report covering [agreed measures]. Any speaking contribution would need to meet our programme's editorial requirements.

If meetings matter more than exposure, we can discuss an invitation process for interested attendees. We wouldn't guarantee that a particular executive will attend or promise contacts who haven't agreed to hear from your team.

Is [objective] a priority for this budget period? If so, could we arrange a short call with the person responsible for event partnerships? I'll send the audience summary and relevant programme detail beforehand.

Best,

[Your name], [role] | [conference business] | [contact details]

Be careful with the phrase "qualified leads". Agree what qualifies someone, how interest is recorded and who follows up. A badge scan identifies an interaction under your chosen process; it doesn't prove purchase intent or permission for every future marketing use.

5. Sponsorship letter for a school event or programme

This version is useful when an education event has a genuine sponsorship offer and the institution permits it. Keep the educational purpose clear. Sponsor activity must fit the setting, especially where students are children, and the school should approve the proposed experience before you approach brands.

Subject: Supporting [STEM Discovery Day] at [school]

Hi [name],

[School or organising body] is hosting [STEM Discovery Day] on [date] for [confirmed participating groups]. The programme includes [specific learning activities], and we're looking for a partner to support [defined activity or resource].

Your work in [relevant area] could be useful to this audience. The proposed support is [cash amount or specified resources]. In return, we can offer [school-approved acknowledgement] and [approved demonstration opportunity], subject to our safeguarding and content requirements.

We would agree staffing, materials, access arrangements and supervision in advance. The package doesn't include student contact details, compulsory marketing signups or permission to reuse student photographs. Any separate request involving children would follow the institution's approval process and applicable requirements.

Would your team consider this type of education partnership? I can share the approved programme outline and explain the resources we need.

Thank you,

[Your name], [role] | [institution] | [contact details]

If the event has no paid-ticket or commercial purpose, its economics will differ from the rest of this guide. Adapt the relevant parts without pretending that audience access is always appropriate. The useful principle is still to describe the support, permitted recognition and delivery responsibilities accurately.

6. Sponsorship letter for a food or night market

A market sponsor may value local product trial and a relevant buying occasion. Check how the activation affects paying vendors. A sponsor giving away a competing product beside a trader can damage the relationship that helps make the market viable.

Subject: [City Night Market] tasting partnership in [location]

Hi [name],

I'm [your name] from [Riverfront Events], producing [City Night Market] at [venue] on [dates]. Our previous edition recorded [verified unique attendance], and [relevant local audience evidence] suggests a connection with your [product range].

We're proposing a [named tasting experience] at [price]. The package would include [defined location], [agreed event promotion] and [specific recognition]. We would provide [confirmed services]; your team would supply [products, equipment or staff].

Before confirming, we'd check food handling, power, waste and delivery requirements with the venue. We'd also agree the sampling offer so it works alongside our traders. Attendees could choose to sign up directly with your team through a clearly explained process, rather than having their ticket details passed over.

Would this fit your local marketing plans? I can send the site layout and arrange a call to discuss the tasting experience and what we'd report afterwards.

Thanks,

[Your name], Partnerships Manager | [business] | [contact details]

Ask how much stock the sponsor can supply and what happens if it runs out. Don't sell unlimited sampling or imply every visitor will try the product. An agreed operating window and distribution count are easier to deliver and explain than an unsupported claim about total audience engagement.

7. Sponsorship letter for a networking or professional mixer

For a smaller professional event, the quality of the interaction may matter more than mass exposure. Protect the attendee experience. A recruiter taking part in useful introductions is different from a sponsor turning the whole evening into unsolicited sales pitches.

Subject: Partnership for [Tech After Hours], [date]

Hi [name],

We're hosting the next [Tech After Hours] at [venue] on [date] for [specific professional audience]. We currently have [paid bookings], and the event capacity is [capacity]. [Verified detail about the audience] looks relevant to your team's work in [area].

We're offering a [named partnership] at [price], including [defined presence] and [specific promotional inclusion]. We'd like to shape the activity around conversations attendees choose to have, such as an optional [advice session or introduction format].

We can report attendance and participation in the agreed activity. Introductions would depend on attendee interest, and the sponsorship wouldn't include a full attendee contact list. We'd confirm your team's role and the host's introduction before the event.

Is this the sort of local professional partnership you're considering? If so, I can send the format and arrange a short discussion about fit.

Cheers,

[Your name], Event Producer | [business] | [contact details]

Be specific about sponsor guest tickets. They use capacity and can replace paid sales. Agree the allocation, booking deadline and any release of unused places before treating hospitality as a cost-free addition to the offer.

8. Sponsorship letter for a virtual or hybrid event

Separate registrations, live attendees, unique viewers and video views. Those figures measure different behaviour. A hybrid event also has different opportunities in the room and online, so a sponsor needs to know which parts its package covers.

Subject: [FutureWork Live] content partnership for [topic]

Hi [name],

[FutureWork Live] takes place on [date], with [in-person format] at [venue] and [online format]. The programme addresses [specific audience problem], which connects with your work on [verified relevant topic].

We're proposing a [named session or content] partnership at [price]. It includes [defined live placement], [agreed recording rights] and [specific promotional inclusion]. Our previous edition recorded [verified live attendance measure] and [separately defined replay measure] during [reporting period].

For this edition, we'd agree a report covering [available measures], with registrations and attendance reported separately. We'd also confirm how any optional sponsor signup works, how long the recording remains available and what happens if the live stream is interrupted.

Would this fit your content or event partnership budget? I can share the programme, reporting definitions and a proposed production schedule before a call.

Best,

[Your name], [role] | [business] | [contact details]

Confirm recording permissions for speakers and materials before selling reuse rights. A sponsor's ability to share a clip on its own channels shouldn't depend on permissions you haven't obtained. Settle that before promising a content package in the letter.

Price the offer before you negotiate

A sponsorship letter can produce a deal that sounds successful while making little financial contribution. Work out what the package costs you to deliver before adding benefits or agreeing to a discount.

Consider this hypothetical example, with all amounts in USD. A sponsor pays $6,000. The extra build and staffing cost $1,400, printing costs $250, and payment plus administration costs are budgeted at $350. That leaves $4,000 before tax, shared event overhead and any other costs. The $6,000 is the sponsorship revenue; the $4,000 is what remains after those specified direct costs. Neither figure proves that the whole event is profitable.

Now suppose the sponsor asks for extra filming and editing that costs $1,200, without increasing its payment. The remaining amount falls to $2,800. You might still accept if the arrangement has a clear business reason, but you should make that choice with the cost visible. "We'll add a recap video" is a financial decision even when it appears in a friendly email.

In-kind support needs the same discipline. If a sponsor provides $3,000 of products at its stated retail value, that doesn't mean you've saved $3,000. If the products replace a $700 purchase you actually planned to make, the avoided cost is $700 before accounting for any handling or delivery expense. If you weren't going to buy them, record the practical benefit without treating the retail value as cash income.

Keep unsigned opportunities separate from committed revenue in your event budget. A positive reply isn't payment, and an approved package may still have conditions. Check when cash will arrive against your supplier deadlines. Sponsorship can help fund production, but a payment due after the event won't cover this month's deposit.

If the sponsor's budget is lower than your proposed price, change the scope before cutting the fee. You could reduce the operating hours, remove an expensive production item or offer a smaller guest allocation. Explain what changes and recalculate the cost. A smaller package that still solves the sponsor's problem can be a better deal for both sides.

Sometimes the answer should be no. If the sponsor requires exclusivity you can't grant, attendee data you can't supply or production work your team can't manage, a discount won't resolve it. Explain the constraint and offer a workable alternative if one exists. Your event still has to meet its commitments to paying attendees and other partners after the sponsorship is signed.

Turn the letter into a package your team can deliver

Once a sponsor shows interest, write down the details behind each benefit. "Social promotion" might mean one post or an entire campaign. "Exclusive partner" might mean one product category, one activation area or every event you run. Leave those phrases undefined and both parties can believe they've agreed to different deals.

For each commitment, specify the deliverable, quantity, location or channel, deadline and responsible person. Record what the sponsor must supply and the approval dates. If a logo is due before print production, state the consequence of a late file before it happens. Don't let your production team discover a custom promise after the agreement is signed.

Separate the sponsorship fee from the sponsor's activation costs. A booth space may be included while furniture, transport, electricity or specialist labour are charged separately. If you're supplying those services, include them in your costing. If someone else supplies them, explain who the sponsor needs to contact and when.

Agree how you'll handle cancellations, changes in format, delayed assets and undelivered benefits in the written agreement. A replacement benefit should solve the sponsor's actual problem. Offering another social mention doesn't automatically replace a cancelled demonstration that was the reason it bought the package.

When the offer is ready, avoid recreating the same pricing and availability in every email. With Loopyah's event sponsorship pages, you can put priced packages, included benefits and quantities on a private page and send the link to selected brands. Packages can use direct purchase or an application requiring your approval. Sponsors can also ask about a custom deal.

That helps with the purchase and administration, but your team still needs to cost the offer, choose suitable partners and deliver the commitments. Keep the agreed scope consistent wherever the sponsor sees it. If you negotiate a custom change, update the arrangement before asking for payment.

Follow up with information that helps the decision

A useful follow-up answers a likely question or makes the next step easier. "Just checking in" repeated several times rarely adds anything. Decide a sensible follow-up plan around the sponsor's decision date and your production deadlines, then stop if the recipient declines or asks you not to contact them.

For an unanswered first approach, you could write: "I'm following up on the [event] tasting opportunity. The proposed location is [specific site detail], and we would provide [confirmed service]. Is this relevant to your local marketing plans, or is there someone else I should contact?" You've added information and allowed an easy answer.

After a call, summarise what you heard before sending a larger proposal. "You mentioned that product trial matters more than stage branding. I've revised the offer around [activity], with [responsibility] supplied by your team and [responsibility] supplied by ours. Does that reflect the plan you want priced?" This can prevent a long proposal built around the wrong objective.

If a real deadline is approaching, explain what it controls. A print deadline is a reason to confirm artwork. A site-layout deadline is a reason to settle the activation footprint. Don't invent scarcity or say another brand is ready to sign unless that is true.

Commercial outreach also needs a compliant sending process. In the US, the FTC's CAN-SPAM guide for businesses covers commercial email, including business-to-business messages. It addresses accurate sender information and subject lines, advertising identification, a valid postal address and opt-out handling. Check the requirements for your actual sending situation and recipient market before launching outreach.

Agree responsible lead collection before offering access

An attendee buying a ticket hasn't automatically agreed to become every sponsor's marketing contact. Decide what data, if any, the sponsor needs and whether you can provide it lawfully for the intended use. Aggregate attendance information may answer the sponsor's question without identifying anyone.

Where people can choose to hear from a sponsor, make the choice understandable at the collection point. Explain which company will receive their details and why. Keep sponsor marketing choices separate from essential event communications. A vague reference to "partners" can leave attendees unclear about what they're agreeing to.

The UK's ICO explains the need for transparency, an appropriate lawful basis and attention to electronic marketing rules when sharing information for direct marketing. Consent, where relied on, must be valid and specific. The right process depends on the jurisdiction, audience and proposed use; a template sentence alone doesn't settle it.

Discuss this before the sponsor purchases. Agree who collects the information, who receives it, what notices people see, how choices are recorded and who handles requests afterwards. Don't promise a full attendee export and leave your team to discover later that the package can't be delivered as sold.

Report what happened and use it to discuss renewal

Set the reporting plan while the opportunity is still being agreed. If nobody is assigned to record sample distribution or photograph placements, the evidence may be gone by the time you write the report. Choose measures your team can collect reliably without disrupting the event.

Show the agreed commitment beside the delivered result. For a sponsored session, that could include the scheduled time, actual attendance measure, approved content and available engagement information. For sampling, it could include operating hours, units distributed and any limitations in counting. Explain missed commitments and proposed remedies directly.

Keep outputs and business outcomes separate. A delivered email, a booth conversation and a completed sponsor signup are different results. If the sponsor later shares attributable sales, explain the attribution method and period rather than presenting every subsequent purchase as caused by the event. Nielsen's explanation of its sponsorship measurement approach distinguishes exposure, fan information, brand impact and sales impact. That distinction helps you avoid claiming more than your evidence supports.

Arrange a debrief around what the sponsor wanted to learn. Ask which interactions were useful, whether the operational arrangements worked and what would need to change for the next edition. Your own review should include delivery costs and staff time, so a happy sponsor doesn't conceal an arrangement that's too expensive for you to repeat.

Before you send your letter

Choose the template closest to the opportunity, then replace every sample detail. Check the audience evidence, cost the proposed benefits and confirm who can approve the deal. Read the letter once for accuracy and once as the person being asked to spend the money.

Your offer should be understandable without a call, even if a call is the next step. The sponsor should know what the event is, why the audience is relevant, what you're proposing and what information you can provide next. If one of those answers is still vague, resolve it before adding another benefit.

For context on why measurement should be discussed early, the Forrester analysis considers the challenge in large-scale sports sponsorship. Your own proposal still needs evidence about your event and an offer you can afford to fulfil.
