How to think about donor acquisition questions, updated for 2027

What to take away

The question that decides the budget

Most acquisition reviews start in the wrong place. They ask which channel is cheapest per gift. The useful question is which channel produces donors who are still giving in year two.

Write it as one line: cost per retained donor equals total spend divided by the number of donors who gave a second gift within 12 months. Substitute your own figures. The channel with the lowest cost per gift often loses on this measure, because a small one-time gift from a sweepstakes entry rarely repeats.

Five questions to settle before the next appeal:

Track two numbers side by side, net acquired donors and later retention. Net means gifts minus refunds, chargebacks and duplicates. Retention means the share who gave again in the following 12 months.

Consent, fit and mission understanding

Consent questions are where marketing plans meet law, so keep them factual. Under CASL, express consent lasts until withdrawn.

Implied consent runs on a clock set by how you got the address. Commonly cited windows are 24 months from the last donation or transaction, and 6 months from an inquiry. A purchased list carries no implied consent at all.

Business card, contest entry and list purchase each carry a different window. Confirm your own position with the CRA and a qualified Canadian charity lawyer.

For donor data, PIPEDA, BC PIPA and Quebec Law 25 and Bill 96 add their own requirements on collection, use and disclosure. Quebec's Law 25 phased in through 2023 and 2024, and it applies to any charity holding data on Quebec residents.

Four consent questions to answer before a 2027 send:

Donor fit is not a feeling. Ask whether the person gives again, whether they name the mission correctly when a volunteer calls, and whether they can say what the gift funds. A donor who cannot describe the program is a lapsed donor with a delay.

Mission understanding is measurable at the point of the second ask. If a thank-you letter explains the program and the next appeal does not, expect the drop-off to land there.

Where acquisition goes wrong

Three failures recur in nonprofit programs.

Lapsed-donor spam. A team reactivates a cold list without checking consent dates, deliverability collapses, and the sending domain loses reputation for months. Google Postmaster Tools reports complaint rates by domain, and a rate at or above 0.3% puts bulk delivery at risk.

Unverifiable agency pitches. A vendor quotes a cost per donor with no definition of retained, no refund treatment and no source data. Ask for the arithmetic and the cohort window before signing. Two questions settle it: which donors count as retained, and when does the cohort close?

Campaigns that stall at sign-off. Copy waits on legal, the send date passes, and the appeal ships after the giving season it was written for. Giving Tuesday falls on the Tuesday after US Thanksgiving, and December 31 does not move. A legal review that lands in January is a missed year.

A worked example

A program spends $12,000 on a channel and acquires 400 first-time donors. Cost per gift is $30, which looks strong.

Of those 400, 96 give again within 12 months. Cost per retained donor is $125. If the average second gift is $60, the channel is not paying back on its own.

The fix is rarely the channel. It is the follow-up: a thank-you call, a program update at day 30, and a second ask timed to the donor's own giving date. Donor acquisition planning that skips this step is buying names, not donors.

Direct mail acquisition in the US and Canada is commonly cited at roughly $1.00 to $1.50 spent per dollar raised in year one, with payback in later years. Treat that as a typical range, not a target.

Governance and the review date

Give the acquisition decision a named owner, a population, a period and a stop rule. Record what would change the answer, such as a refund rate above your threshold or a retention rate below it.

Two public frameworks help structure the review without deciding it. The NIST AI RMF Playbook sets out voluntary govern, map, measure and manage actions when software touches a workflow. The NIST Privacy Framework starting guide describes a voluntary process for identifying privacy risk and assigning owners. Neither is legal clearance.

For data quality, the GAO data reliability guide ties quality to intended use and asks for documented assessment. When you choose a CRM or email platform, the GOV.UK technology selection guidance covers adaptable choices, data control, security review and ownership cost.

Named systems to weigh: Salesforce Nonprofit Cloud, Blackbaud Raiser's Edge NXT, Little Green Light, Neon CRM and Bloomerang for donor records. Smaller shops also look at DonorPerfect and Givebutter. For email, Mailchimp, Constant Contact and Bonterra's EveryAction carry most mid-size programs.

Salesforce's Power of Us program is commonly cited as giving eligible nonprofits 10 free licenses. Blackbaud's Raiser's Edge NXT is quote-based rather than list-priced. Small-shop CRMs typically list entry plans between $40 and $200 per month as of 2026, priced by contact count and users. Confirm current figures with each vendor.

Common questions

How do we set a cost-per-retained-donor threshold?

Compare the figure against your own multi-year giving data, not a published average. If a donor's projected lifetime giving is below the cost to acquire and steward them, the channel needs a different follow-up or a smaller budget.

The CRA's fundraising guidance offers a program-level guardrail: a cost ratio under 35% of revenue is generally acceptable, and above 70% needs a strong explanation.

What counts as valid consent for an acquisition list?

It depends on how the address was obtained and which law applies. CASL implied consent expires, and PIPEDA, BC PIPA and Quebec Law 25 add conditions. Name the source and date on every record, and confirm the rule with the CRA and a charity lawyer.

How long should an acquisition test run?

Long enough to see second gifts, which usually means 12 months for the cohort. A 90-day test measures response, not retention, and will flatter the wrong channel.

When should a campaign stop?

Set the stop rule before launch. A refund rate above your threshold, a retention rate below it, or a consent gap in the list are all reasons to pause and correct rather than scale.
