When to Send a Sponsorship Renewal Letter

Renewal starts at the event, not after it. Collect the results each sponsor cares about while the show is running, send the thank you, send the recap, and then ask. A renewal letter that arrives before the recap asks the sponsor to commit without evidence; one that arrives months later competes with every other event that asked first.

Sponsor renewal timeline (example timing)
When	What to send	Purpose
Within a week of the event	Thank you letter	Close this year warmly, no ask
2 to 4 weeks after	Recap report	Show what the sponsorship delivered
With or just after the recap	Renewal letter with first refusal	Ask for next year with a deadline
1 week after the letter	Follow-up email, then a call	Answer questions, offer the upgrade
At the first-refusal deadline	Last-call email	Release the package if there is no reply
Next sales cycle	Win-back letter to lapsed sponsors	Reopen the conversation

Sponsor renewal timeline (example timing)

Use the sponsor thank you letter for the first message and the sponsorship recap report for the second, so the renewal letter can point to results the sponsor has already seen.

Letter 1: Early Renewal With Results

Subject: [EVENT NAME] [NEXT YEAR]: your [PACKAGE NAME] sponsorship, first refusal until [DATE]

Dear [FIRST NAME],

Thank you again for sponsoring [EVENT NAME] as our [PACKAGE NAME] sponsor. Your support made [SPECIFIC MOMENT, e.g. the opening keynote / the networking lounge] possible.

Here is what your sponsorship delivered this year:
- [RESULT 1, e.g. NUMBER attendees in the room for the session you sponsored]
- [RESULT 2, e.g. NUMBER leads scanned at your booth]
- [RESULT 3, e.g. NUMBER views of your sponsor listing in the event app]
The full recap is attached.

[EVENT NAME] returns [DATES] at [VENUE]. As a returning sponsor, you have first refusal on the [PACKAGE NAME] package [and booth NUMBER] until [DATE], at [PRICE / the same price as this year].

To confirm, reply to this email or sign here: [AGREEMENT LINK]. If you'd like to change anything about the package, I'd be glad to talk it through: [CALENDAR LINK OR PHONE].

With thanks,
[YOUR NAME]
[TITLE], [EVENT NAME]
[EMAIL] | [PHONE]

Letter 2: Upgrade Offer

Subject: More [GOAL, e.g. qualified meetings] at [EVENT NAME] [NEXT YEAR]

Hi [FIRST NAME],

When we spoke after the event, you mentioned that [SPONSOR GOAL, e.g. you wanted more time with decision makers]. I've put together an option for next year with that in mind.

This year ([CURRENT PACKAGE], $[PRICE]):
- [CURRENT BENEFIT]
- [CURRENT BENEFIT]

Next year ([UPGRADE PACKAGE], $[PRICE]):
- Everything in [CURRENT PACKAGE]
- [NEW BENEFIT, e.g. a hosted roundtable with NUMBER invited attendees]
- [NEW BENEFIT, e.g. a corner booth near the main entrance]

Based on this year's [RESULT, e.g. NUMBER booth visits], [ONE SENTENCE ON WHY THE UPGRADE FITS].

Your current package is also held for you until [DATE] if you'd rather keep things as they are. Could we take 15 minutes this week to choose? [CALENDAR LINK]

Best,
[YOUR NAME]

Letter 3: Lapsed Sponsor Win-Back

Subject: [EVENT NAME] has changed since [LAST YEAR THEY SPONSORED]

Hi [FIRST NAME],

It's been [TIME] since [COMPANY] sponsored [EVENT NAME], and a few things have changed that I think are relevant to you:
- [CHANGE 1, e.g. attendance grew to NUMBER, with more JOB TITLES]
- [CHANGE 2, e.g. a new track or show floor area focused on TOPIC]
- [CHANGE 3, e.g. a response to feedback they gave]

When you last sponsored, you told us [FEEDBACK OR REASON FOR LEAVING]. This year we [WHAT YOU CHANGED].

If a full package isn't the right starting point, [SMALLER OPTION, e.g. a session sponsorship or an exhibit booth with a logo listing] is a lower-commitment way to see the new audience.

Would you be open to a short call in the next two weeks? [CALENDAR LINK]

Best regards,
[YOUR NAME]

Recap Data and Renewal Tips

Use only figures you can back up. If a number is an estimate, say so. Pick the two or three results closest to what the sponsor told you they wanted, rather than every metric you have.

Recap data to include, by sponsor goal
Sponsor goal	Results to quote	Where it comes from
Brand visibility	Logo placements, sponsor listing views in the app, email and social mentions	Event app analytics, email platform
Leads	Booth scans or leads captured, meetings held	Lead retrieval exports, the sponsor's own count
Thought leadership	Session attendance and ratings	Session check-ins, session ratings
Hospitality and relationships	Attendance at the sponsored reception or lounge	Check-in counts, staff estimate
Community or CSR	Attendees, volunteers or funds raised for the cause	Your registration and fundraising records

Recap data to include, by sponsor goal

Send the letter from the person the sponsor dealt with during the event
Name a deadline for first refusal and hold to it
Offer the same package first, then the upgrade; never only the upgrade
Mention a price change openly, with the reason, rather than in the agreement
Attach the recap or link to it; don't make the sponsor ask
Follow up by phone a week after the email

If next year's price is changing, the guide on how to price sponsorship packages explains how to set tiers from what each benefit costs and delivers. Sponsorship management software keeps packages, inventory and sponsor payments in one place, so you know which packages are renewed and which are open to sell.

How Map D Helps

Back Every Renewal Letter With Real Results

Map D doesn't write the letter, but it gives you the numbers to put in it and somewhere for the sponsor to buy again. Sponsorships are items you sell alongside booths, sponsors appear on your Homebase, floor plan and mobile app, and sponsor analytics show which sponsors attendees viewed. You can build the floor plan for one event free; publishing, sharing the map and selling booths and sponsorships need a paid plan (from $1,500 per event).

FAQ

Questions Organizers Ask

When should you send a sponsorship renewal letter?

Many organizers send it two to six weeks after the event, once the recap report is ready and before sponsors set next year's budgets. If you know a sponsor plans budgets on a set cycle, time the letter a month or two before that date.

What should a sponsorship renewal letter include?

Thank the sponsor, give two or three specific results such as attendance, booth visits, leads or impressions, name the package and price you are offering for next year, state a deadline for first refusal, and include a clear next step such as a reply, a call or a link to the agreement.

How do you ask a sponsor to upgrade?

Offer the same package with something added, such as better placement or a new benefit, or present a higher tier with the results that justify it. Tie the upgrade to a goal the sponsor told you about, and keep the current package available so the choice isn't upgrade or leave.

How do you win back a sponsor who didn't renew?

Open with what has changed since they last sponsored, such as audience growth or a new format, acknowledge any problem they raised, and offer a smaller first step or a trial benefit. Keep it short and ask for a call rather than a signature.

What if a sponsor doesn't reply to the renewal letter?

Follow up once by email after a week, then call. If there is still no answer by your first-refusal deadline, send a last-call message saying the package will be offered to other sponsors on a set date, and then do it.

Is a renewal letter different from a sponsor thank you letter?

A thank you letter closes this year and is sent soon after the event. A renewal letter looks ahead and asks for next year's commitment. You can combine them, but separate letters let the thank you stand on its own and give the renewal its own results and deadline.
