How to Increase Gift Aid Claims: The Two-Email Sequence That Recovers Missed 25%

Last updated: 13 May 2026 · By Zain, Founder of Build Better · 6 min read

Gift Aid recovery is the process of getting UK taxpayer donors who skipped the Gift Aid opt-in to confirm their status after the fact, so your charity can claim the additional 25% from HMRC on donations they've already made.

Quick answer: To turn Gift Aid "No" donors into "Yes" donors, send a two-email sequence to every UK taxpayer who didn't tick Gift Aid on their donation. Email one (sent 24 hours after the donation) tells them how much extra you can claim and gives them one button to confirm. Email two (sent exactly two days later) is a short reminder with the same call to action. Charities using this sequence typically recover 20–30% of missed Gift Aid, adding tens of thousands of pounds a year with no additional fundraising effort.

20–30% of "No" donors

If your charity is collecting Gift Aid from less than 60% of eligible donors, you're leaving thousands of pounds on the table every month. That money is sitting there, already approved by HMRC, waiting for a tick in a box that never happened.

The frustrating part is that most "No" donors aren't actually opposed to Gift Aid. They don't fully understand how it works. They skipped past it on the donation page. No one's ever asked them properly. And every month that passes is another 25% of free income you'll never recover.

We've worked with charities that took their Gift Aid opt-in rate from 40% to over 80% with a single follow-up email. No new technology. No additional ad spend. Just one well-crafted message sent at the right time.

Why this is worth your attention this week

Every time a UK taxpayer donates without ticking Gift Aid, you lose 25%. At no cost to them.

That's £25 for every £100. £2,500 for every £10,000. £25,000 for every £100,000. It's not marginal. For any UK charity with a meaningful donor base, this is one of the largest sums of money you're failing to claim, every single year.

And the structural problem is simple: most donation pages bury the Gift Aid opt-in below the donate button. Donors are emotional in that moment. They click, they pay, they move on. The opt-in gets skipped. Not maliciously, just because their attention has already shifted to "is the payment going through."

Most charities then write Gift Aid follow-ups that sound like tax paperwork. "In accordance with HMRC regulations, we are pleased to inform you that you may be eligible…" Nobody opens that email. Nobody acts on it.

So we're going to fix both the structure and the language.

The two-email sequence that recovers Gift Aid

This is the entire workflow. Two emails. Sent automatically. Total setup time: one afternoon. Total ongoing cost: zero.

Step 1: Pull your non-Gift Aid donors

Export your donor list and filter for any donation tagged "Gift Aid = No" where the donor has indicated they're UK-based. These are your low-hanging fruit. They've already donated to you. The hardest part of the relationship is done. Now you're just asking them to flick a switch on income you've already received.

If your CRM can segment by recency, prioritise donors who gave in the last 90 days. The fresher the donation, the higher the opt-in rate on the follow-up.

Step 2: Send the "You forgot something" email

The email needs to do three things clearly, in this order. Tell the donor what they did. Tell them exactly how much extra you can claim. Make the action a single click.

Subject: You forgot something on your donation

Hi [Name],

I noticed you didn't tick Gift Aid on your last donation of £[donation_amount].

Most people don't notice this. It's a small box that's easy to miss.

If you click the button below to confirm you're a UK taxpayer, we can claim an extra £[donation_amount × 0.25] from the government at no cost to you.

Just press the button and we'll do the rest.

[Yes, I'm a UK taxpayer. Claim Gift Aid]

Thank you again for giving so generously.

[Your Name] [Your Charity Name]

That's the whole email. No mission statement at the top. No paragraph about your work. No newsletter content. The donor doesn't need to be re-sold on the charity. They already gave. They need to understand what they missed and how to fix it in one click.

Personalisation matters here. Use the actual donation amount. Use the actual extra figure. A donor who gave £40 should see "we can claim £10 extra." Not a generic explainer about percentages. Specificity converts.

Step 3: Send a reminder exactly two days later

This is the step that doubles your recovery rate, and the step most charities skip because it feels pushy. It isn't. Day one after a donation might feel like a nudge. Day two feels like a helpful correction. You're making sure they didn't miss it.

The reminder uses the same message and the same call to action. Same button. Don't redesign it. Don't soften it further. Donors who didn't open the first email open the second. Donors who opened the first but got distracted come back to it.

Subject: Just checking. Should we claim Gift Aid on your donation?

Hi [Name],

Just following up in case you missed this. We can still claim that extra 25% if you confirm below.

[Confirm Gift Aid]

That's it. Two lines and a button.

What this typically recovers

A well-executed two-email sequence usually converts 20–30% of "No" donors to "Yes." On a charity claiming £200,000 a year in Gift Aid, that's potentially another £40,000–£60,000 in recovered income. Compounding annually. With no additional fundraising effort.

This isn't a marketing campaign. It's an administrative fix that happens to involve email. The math is straightforward, the donor experience is positive (you're handing them free impact, not asking for more money), and the work is done once.

If you only do one thing in your fundraising operations this quarter, do this. The cost is one afternoon. The return shows up in your next Gift Aid claim.

Frequently asked questions

What is Gift Aid and how does it work for UK charities?

Gift Aid is a UK government scheme that lets registered charities claim an extra 25p for every £1 donated by a UK taxpayer, at no cost to the donor. To claim it, the donor must confirm they're a UK taxpayer and have paid enough income or capital gains tax in the year to cover the amount being claimed. Charities then submit claims to HMRC, usually monthly or quarterly, and receive the additional payment directly.

How much extra income can my charity claim through Gift Aid?

For every £100 donated by an eligible UK taxpayer, your charity can claim an additional £25 from HMRC. On £10,000 of donations, that's £2,500. On £100,000, it's £25,000. The Higher Rate Relief on top of standard Gift Aid means donors paying higher-rate tax can claim further relief themselves, which often motivates them to give again.

Why do so many donors skip the Gift Aid opt-in?

Most donors don't actively reject Gift Aid. They miss it. The opt-in usually appears below the donate button on the donation page, after the donor has already committed emotionally and is focused on completing payment. They click pay and move on. The skip rate is structural, not ideological. Which is why a clean follow-up email recovers such a high percentage.

What's the best subject line for a Gift Aid follow-up email?

"You forgot something on your donation" consistently outperforms more formal subject lines. It's personal, low-pressure, and creates curiosity without sounding like a marketing email or tax paperwork. The follow-up reminder works well with "Just checking — should we claim Gift Aid on your donation?" Both subject lines avoid HMRC language and treat the donor like an adult who simply missed a checkbox.

When should I send a Gift Aid recovery email?

Send the first email roughly 24 hours after the donation. The donor's attention has settled, but the donation is still fresh in their memory. Send the second email exactly two days after the first. Donors who didn't open the original tend to open the reminder. Donors who opened but got distracted come back to it. Beyond five days post-donation, recovery rates drop sharply.

Is it pushy to send a reminder email for Gift Aid?

No. A reminder framed as a helpful correction ("just checking in case you missed this") is interpreted as service, not pressure. You're not asking the donor for more money. You're telling them about free income they're entitled to enable. Charities that send the reminder typically recover 50–100% more Gift Aid than charities that send only the first email.

How much Gift Aid can I realistically recover with this sequence?

Well-executed two-email sequences typically convert 20–30% of "No" donors to "Yes." If your charity currently has a 50% Gift Aid opt-in rate and you have £200,000 a year in eligible donations, recovering 25% of the missed half means roughly £6,250 in additional Gift Aid claimed per year. Compounding as your donor base grows.
