Interactive Email for Nonprofit Fundraising & Donations

A donation ask that routes through an outside page loses people at the click. A Product block takes the gift directly through your own connected Stripe account, an RSVP handles headcount for a gala or fundraising event, and a Countdown keeps a matching-gift or year-end deadline visibly ticking down in every open.

Double your impact before midnight

A donation ask that routes through an outside page loses people at the click. A Product block takes the gift directly through your own connected Stripe account, an RSVP handles headcount for a gala or fundraising event, and a Countdown keeps a matching-gift deadline visibly ticking in every open.

Every extra click between "I want to help" and "I gave" costs conversions. Keeping the ask, the urgency, and the payment all inside one email removes as many of those clicks as an inbox reasonably can.

Take the gift without leaving the email

A Product block handles the donation itself — set one or more suggested amounts (a $25/$50/$100 ladder, say) and checkout runs through your own connected Stripe account. MailInApp never holds the funds or sees card details; it just renders the button and confirms the payment via Stripe's own webhook.

Make urgency visible, not just stated

A Countdown block regenerates fresh on every open, computed from whatever deadline you set — a matching-gift window, a year-end giving cutoff — so it stays accurate no matter when a donor actually opens the email. A static "ends soon" line goes stale the moment it's written; the countdown never does.

Fill the gala in the same email

If there's an event attached to the campaign, an RSVP block takes headcount with a capacity cap and automatic waitlisting once the venue's full — the same tap-to-respond flow whether it's a formal gala or a casual fundraising mixer.

Say thank you automatically

A successful payment can trigger an automatic lifecycle thank-you email, and Stripe itself issues the payment receipt — donors get confirmation without you having to send it by hand for every gift.

Getting started

Add a Product block per suggested donation amount, a Countdown for any matching-gift deadline, and an RSVP if there's a related event. Checkout runs on your own connected Stripe account — see Responses & webhooks for how donation and RSVP activity show up on your dashboard.

A typical build-and-send sequence

  1. 1

    Build the appeal

    Add a Product block for the donation amount, a Countdown for a matching-gift or deadline window, and an RSVP if there's a related event to fill.

  2. 2

    Take the gift in the email

    Checkout runs on your own connected Stripe account — MailInApp never holds the funds or sees card details, and a receipt goes out automatically.

  3. 3

    Track the campaign as it runs

    The countdown keeps counting down accurately on every open; the Responses dashboard tracks donations and RSVPs together as they come in.

  4. 4

    Follow up with a thank-you

    Every paid donation can trigger a lifecycle thank-you email automatically, and a low-inventory or sold-out gala RSVP is handled the same way a ticketed event would be.

Frequently asked questions

Does MailInApp hold or process the donation funds?

No — checkout runs on your own connected Stripe account (Stripe Connect). MailInApp never holds funds or sees card details; it just renders the donation button and confirms the payment via Stripe's own webhook.

Can I offer a few suggested donation amounts?

Set up a Product block per suggested amount (e.g. $25 / $50 / $100), each with its own price, so a donor picks the one that fits rather than typing in a custom figure.

Can I show a live countdown to a matching-gift deadline?

Yes — the Countdown block regenerates fresh on every open, computed from the deadline you set, so it stays accurate no matter when a donor opens the email, right up to when the matching window closes.

Can I combine a donation ask with a gala RSVP in the same email?

Yes — add both a Product block for the donation and an RSVP block for the event; RSVP handles capacity and waitlisting for the gala independently of the donation itself.

Do donors get an automatic thank-you and receipt?

Yes — a payment confirmation triggers an automatic lifecycle email, and Stripe itself issues the payment receipt; you can also follow up manually via support tickets for a personal thank-you note.
