Donor Acquisition: How to Find First-Time Donors Who Stay

A youth soccer nonprofit holds its first spring 5K and brings in 210 new donors, mostly friends and coworkers of the runners. The board celebrates. Twelve months later, the treasurer notices that only 32 of them have given again. The 5K wasn't a failure, but the plan stopped at the finish line.

Donor acquisition is the work of turning people who have never given to you into first-time donors, at a cost you can recover as they keep giving. A good acquisition plan answers four questions before any campaign starts: who you're trying to reach, through which channels, what you'll ask them to give to, and what happens in the 90 days after their first gift.

This guide covers how many new donors you actually need, where to find them, how to design a first-gift offer, how to calculate acquisition cost, how to onboard first-time donors, and how to test your way to better results. Every example uses US dollars and fictional organizations.

Why Acquisition and Retention Belong in One Plan

New donors replace the ones you lose. That makes your retention rate the starting point for any acquisition goal.

According to the Fundraising Effectiveness Project, total charitable dollars grew by an estimated 5.0% in 2025 while the number of donors fell by 3.6%, and overall donor retention was 43.3%. In other words, across the organizations in that data set, more than half of donors didn't give again the following year. Those donors have to be replaced just to stand still.

You can calculate your own target in one line:

New donors needed = (current donors × (1 − retention rate)) + growth target

A neighborhood arts center has 800 donors and 45% retention. It keeps 360 and loses 440. To grow by 5%, to 840 donors, it needs 480 new donors next year. If it raised retention to 55%, it would need only 400. Every point of retention you gain lowers the acquisition bill.

That's why this guide spends as much time on the first 90 days as on finding donors. For the long-term relationship after that, see our guide to donor stewardship.

Start With People Who Already Know You

The cheapest new donors are usually people who already have a relationship with your organization but have never made a gift. Most organizations have more of them than they realize.

Build these groups as saved segments in your database so you can reach them again without rebuilding the list each time. In campai, tags and filters on contact records can be saved as segments, and the communication tools let you send newsletters to those segments and schedule them in advance.

Treat these people with the same care as donors: they already trust you. Before the first ask, make sure they've heard what you've accomplished, not just what you need.

Choose Your Acquisition Channels

No single channel works for every organization. Pick two or three that match your audience, budget and staff time, and run them well.

Each of these has its own guide: peer-to-peer fundraising, direct mail fundraising, donation pages, Google Ad Grants and Giving Tuesday ideas.

If you solicit donors in other states, check whether those states require charitable solicitation registration. Many do, and the rules vary, so ask your state attorney general's charities office or a qualified adviser before a multistate campaign.

Design a First-Gift Offer People Can Say Yes To

People rarely give their first gift to an organization. They give to a specific, tangible result that feels within reach. A strong first-gift offer has four parts:

1. A concrete outcome. "$40 provides a week of after-school meals for one child" is easier to picture than "support our programs." Make sure the numbers are true and that you can show where the money goes.
2. A suggested amount. Offer two or three amounts based on what first-time donors actually gave last year, with the middle one preselected.
3. A reason to act now. A matching gift, a season, an event date or a funding gap with a deadline.
4. An easy path. A short donation form, mobile friendly, with an option to make it monthly.

A sample first-gift appeal, written for a fictional youth music program:

Can you give a student their first instrument this fall?

Thirty-two students start our free strings program in September. Twelve still need violins. A gift of $75 rents a student's violin for the whole school year, and a local family foundation will match every gift through September 15.

[Give $75] [Give $150] [Choose your amount]

You'll receive a receipt right away and a photo of the first rehearsal in October.

Be careful with thank-you gifts. A tote or mug can work, but anything beyond small, logo-bearing items changes how much of the gift may be deductible and adds paperwork. Our guide to donation receipts explains the IRS limits on insubstantial benefits.

Calculate What Acquisition Really Costs

Acquisition almost always costs more per dollar raised than asking existing donors. That's fine, as long as you know the numbers and the donors stay.

Cost per new donor = campaign cost ÷ number of new donors
First-year return = first-gift revenue ÷ campaign cost
Cost per retained donor = campaign cost ÷ new donors who give again within 12 months

Worked Example: Three Campaigns Compared

The youth soccer nonprofit ran three acquisition efforts last year. These are fictional planning figures, not benchmarks.

Judged on the first year alone, the mailing looks like a loss. Twelve months later, the picture changes:

What the board learned:

• The 5K brings volume but low loyalty. The fix isn't to drop it, but to add a follow-up plan specifically for runners' supporters.
• Warm email is the most efficient channel, but it's limited by the size of the list. Growing the subscriber list is itself an acquisition strategy.
• The mailing may pay off over time, if its donors keep renewing at a higher rate. The board decided to test it once more with a better-targeted list before deciding.

To decide how much you can afford per new donor, compare cost per new donor with the long-term value of the donors you acquire. Our guide to donor lifetime value shows how to calculate that value by cohort and turn it into a spending limit.

Onboard New Donors in the First 90 Days

The period right after a first gift decides whether a donor becomes a supporter or a one-time transaction. Plan it before the campaign launches.

The thank-you letter matters more than most organizations think. Our guide to donation thank-you letters has templates you can adapt.

Capture the Right Data at the First Gift

Your future analysis depends on what you record now. For every new donor, capture:

• the source, such as campaign, event or referral, in a consistent code,
• how they heard about you, if you ask on the form,
• communication preferences and consent, including any request not to be mailed,
• a link to an existing record, if they were already a member, volunteer or attendee.

A donor who's entered twice, once from an event import and once from an online gift, will look like two people, one of whom has lapsed. Our guide to donor data hygiene covers how to prevent that.

Test, Learn and Improve

Acquisition gets cheaper when you test systematically instead of changing everything at once.

What to Test

• Ask amounts: $35, $50, $75 versus $50, $100, $150
• Offer: a specific item ("a violin for a year") versus a general fund
• Subject lines and envelope teasers
• Form length: fewer required fields versus more data
• Monthly option: preselected versus available but not selected
• Channel mix: shifting a share of the budget between channels

How to Run a Fair Test

1. Change one thing at a time.
2. Split the audience randomly, not by region or alphabet.
3. Decide in advance what result counts as a win, such as more new donors, a higher average gift or better 12-month retention.
4. Wait for enough responses. If each version has only a handful of gifts, the difference is probably noise. Repeat the test before changing your whole program.
5. Write down the result, even when nothing wins.

A simple test log keeps the learning from disappearing when volunteers or staff change:

Measure Acquisition Quality, Not Just Volume

A campaign that brings in 500 donors who never give again isn't better than one that brings in 100 who stay for years. Track these numbers for every source:

Review them once a year with your board, alongside your other nonprofit KPIs.

Frequently Asked Questions

What is a good donor acquisition cost?

There's no universal figure. A good cost is one you can recover through the giving of the donors who stay. Compare cost per retained donor with the long-term value of your donors, by channel, rather than looking at first-year results alone.

How many new donors do we need each year?

Multiply your current donor count by your attrition rate (one minus retention), then add your growth target. An organization with 800 donors and 45% retention needs about 440 new donors just to stay the same size.

Is it cheaper to keep a donor than to find a new one?

In direct costs, usually yes. Keeping a donor costs a thank-you, a few updates and a well-timed ask; finding a new one costs a campaign. Run the numbers with your own data to see the gap.

What's the best acquisition channel for a small nonprofit?

Start with your warm audiences: members, volunteers, event attendees and newsletter subscribers who haven't given. Add one outward-facing channel, such as a peer-to-peer campaign or Giving Tuesday, once your onboarding sequence is ready.

Should we buy email lists to find donors?

We recommend against it. People on a purchased list didn't ask to hear from you, and complaints and unsubscribes can hurt the delivery of all your email. Grow your list through events, sign-up forms and partnerships instead.

Next Steps

1. Calculate how many new donors you need next year using your actual retention rate.
2. Build saved segments of members, volunteers and attendees who have never given.
3. Choose two or three channels and write a first-gift offer for each.
4. Plan the 90-day onboarding sequence before the first campaign launches, with an owner for every touchpoint.
5. Set up a source code system and a test log, then review cost per retained donor after 12 months.
