Year-end fundraising emails: a December appeal plan for nonprofits

Year-end fundraising emails: what a December appeal plan looks like

A year-end fundraising email plan is a short, dated series of appeals sent between early December and 31 December, built around one goal, one story and one deadline: 31 December. A large share of yearly donations arrives in December, and the last days of the year are among the busiest for online giving. This guide gives you the calendar, the 31 December send times, a simple tax reminder to put in your emails, the segments to split your list into, and subject lines you can adapt.

GivingTuesday (1 December 2026) is a separate one-day campaign with its own logic. This plan starts after it and assumes you have already thanked your GivingTuesday donors.

Key takeaways

• A large share of yearly donations arrives in December, and the last days of the year are among the busiest for online giving.
• Plan 6 to 9 emails from 8 December to 31 December, with up to three sends on the last day.
• Gifts may be tax-deductible depending on the country: remind donors of the 31 December deadline and point them to their tax adviser or the official tax authority's website.
• Never send the same appeal to everyone. Monthly donors, recent donors and lapsed donors each need a different email, or none.
• Suppress anyone who gives, in real time. Asking a donor who gave an hour ago is the fastest way to lose them.

How much of a nonprofit's annual giving comes in December?

A large share of yearly donations arrives in December, although the exact proportion varies by organisation, cause and channel. Online giving tends to be especially concentrated at the end of the year, because last-minute donors usually give online.

Two practical conclusions. First, one weak December email series can cost a significant part of the year's online income. Second, 31 December is not just another day: the last days of the year are among the busiest for online giving, so plan your strongest sends for them.

What should your appeal say about tax?

Donations may be tax-deductible depending on the country: remind donors of the year-end deadline (31 December) and tell them to check with their tax adviser or the official tax authority's website. In your emails, include the 31 December deadline and a link to your receipt or FAQ page rather than quoting rates.

How many year-end fundraising emails should you send?

Most nonprofits should plan six to nine emails between 8 December and 31 December, with the frequency rising in the last week. Not every supporter opens every email, and the people who give on 31 December are often the same people who ignored your first two messages. The calendar below is built for 2026, when 31 December falls on a Thursday.

If you run a smaller organisation with a list under a few thousand contacts, keep emails 1, 2, 6, 7 and the 31 December sends. Cut the rest before you cut the last three days.

What should you send on 31 December?

Send up to three short emails on 31 December, each one shorter than the last, and remove anyone who has given since the previous send. On the last day, people are not reading long stories; they are acting on a reminder they already intended to follow.

1. 08:00 local time — "Last day". Three to five sentences: the deadline, the goal, how far you are from it, one button. Repeat the tax reminder in one sentence.
2. 14:00 — "Hours left". Sent only to people who have not given in December. Lead with the gap ("We're $3,200 short"). A countdown timer to midnight works well here.
3. 20:00 to 21:00 — "Final call". Plain, almost personal: from the director's name, two or three lines, one link. Send it early enough that a donor can still find their card before midnight.

Three rules make the last day work:

• Suppress donors in real time. Sync your donation form with your email list, or tag every new donor before each send. A donor who receives "Final call" twenty minutes after giving feels unseen.
• Respect time zones. If you have donors in several countries, schedule the sends by local time, so "hours left" is still true when it arrives.
• Test the donation page the day before. Load it on a phone, make a real small gift, and check that the receipt arrives. On 31 December a broken page costs a day's revenue that you cannot recover in January.

If supporters have consented to SMS, one text at around 18:00 complements the emails; keep it to one link and send it only to people who have not given.

December lists are large and many contacts are quiet the rest of the year. Mailpro™ is priced by sends, not contacts, so lapsed donors and old supporters do not inflate your bill: see Mailpro pricing.

How should you segment donors for a year-end appeal?

Split your list by giving history before you write a single email, because the right message for a monthly donor is the wrong one for a lapsed donor. With email segmentation you can build these groups once and reuse them for every send in the series.

How do you win back lapsed donors in December?

Remind lapsed donors of what they already did before asking for anything new. A line such as "In 2024 your $50 paid for two nights of shelter" works better than any new story, because it is about them. Keep the ask at or slightly below their last gift, and stop after two or three emails: a lapsed donor who ignores your whole December series should move into a quieter re-engagement track in the new year, not receive nine appeals. If part of the segment has not opened anything for a year or more, apply a sunset policy before December rather than during it, because a sudden spike of unopened emails hurts the deliverability of the whole campaign.

How do you ask monthly donors for an upgrade?

Ask monthly donors for a small, specific increase, and never for a one-off December gift on top of their monthly gift. A good upgrade email thanks them first, shows what their monthly gift did this year, and offers one concrete step: "Would you add $3 a month? That's one more child's school meals every term." Show the yearly total too, since $3 a month is $36 a year. Give a one-click "keep my gift as it is" option as well; a monthly donor who feels pressured is a cancellation risk, and recurring donors are your most valuable supporters.

The same logic works in reverse in the January thank-you: invite December one-time donors to become monthly donors while their gift is still fresh.

Which year-end fundraising email subject lines work?

Short, specific subject lines work best: under about 50 characters, one idea, and a number or deadline where the stage of the series allows it. Match the subject line to the email's job rather than repeating "Donate now" nine times. More on the craft in our guide to writing effective subject lines.

• Launch: "Maya slept outside last winter" · "Our goal for December: 40 families"
• Proof: "What $30 did this year" · "1,200 meals, and what comes next"
• Matching gift: "Your gift is doubled until 31 December" · "A donor will match your gift"
• Monthly upgrade: "Could you add $3 a month?" · "Thank you for every month this year"
• Tribute gift: "A gift for someone who has everything" · "Still looking for a present?"
• Progress: "We're at 72%" · "$6,000 to go"
• Tax deadline: "Your gift may be tax-deductible" · "Last chance for a 2026 tax receipt"
• 31 December: "Last day" · "A few hours left" · "Before midnight"
• Lapsed donors: "We've missed you this year" · "Remember the shelter you helped?"

Test one variable per email (number vs. no number, question vs. statement) on a small share of the list a few days ahead, then send the winner to the rest. On 31 December there is no time to test; reuse what won earlier in the month.

What should a year-end appeal email contain?

A year-end appeal email needs one story, one number, one ask and one button, and nothing that competes with them. A checklist for each email in the series:

• A named person or a concrete situation, not "the people we serve".
• A goal and a deadline: the amount, and 31 December.
• Suggested amounts tied to outcomes ($25, $50, $100) and pre-filled on the donation page.
• One call to action, repeated as a button and a text link, pointing to a donation page with no navigation away from the form.
• A tax reminder in one sentence: the gift may be tax-deductible, with a link to your receipt or FAQ page.
• A P.S. that restates the ask; many readers scan straight to it.
• Plain, readable design: a single column, large text, and an image only if it carries the story.

Here is a 31 December final-call email you can adapt:

Subject: Before midnight

Anna, in a few hours 2026 closes, and so does our appeal. We're $2,400 from keeping the shelter open every night until March.

A gift of $50 covers two nights of a safe bed. Given before midnight, it may also be tax-deductible for 2026.

[Give before midnight]

Thank you for everything you've made possible this year.
Claire, director

P.S. If you've already given today, thank you, and please ignore this email.

What are the most common year-end appeal mistakes?

• Asking people who just gave. Fix it with real-time suppression or a tag added by your donation form.
• Treating monthly donors like everyone else. One-off appeals to recurring donors cause cancellations.
• Waking a dormant list on 30 December. Sending to thousands of contacts who have not opened in two years raises bounces and complaints at the worst possible moment. Clean the list in November.
• Getting the tax claim wrong. Rules differ by country and by organisation, so keep to a general reminder and point donors to the official tax authority's website instead of quoting rates.
• Late receipts. Donors who need a receipt for their tax return should get it in the first week of January, not in March.
• Stopping on 31 December. The thank-you email is the first email of next year's appeal.

Frequently asked questions

When should I start my year-end fundraising emails?

Start the appeal itself in the second week of December, a few days after GivingTuesday, and prepare segments, the donation page and the tax wording in November. Starting the appeal earlier tends to blur into GivingTuesday and holiday promotions.

Is three emails on 31 December too many?

Not if each email is short and anyone who gives is removed before the next send. The last days of the year are among the busiest for online giving, so 31 December is the day where an extra reminder pays most.

What time should I send the last email on 31 December?

Between 20:00 and 21:00 in the donor's local time. Later sends compete with New Year's Eve plans and leave too little time to complete a gift before midnight.

Should I mention tax benefits in a year-end appeal?

Yes, in one sentence, in the emails from 27 December on: say the gift may be tax-deductible depending on the country, remind donors of the 31 December deadline and point them to their tax adviser or the official tax authority's website. Lead with the impact, not the tax saving.

How is the year-end appeal different from GivingTuesday?

GivingTuesday is a single-day campaign on 1 December 2026 built on collective momentum; the year-end appeal is a month-long series built on your own goal and the 31 December deadline. Run them as two campaigns, and do not send year-end appeals to people who gave on GivingTuesday.
