This is Charitology’s proposed workflow, not a tested intervention or a claim that this method is best. Adapt it to your mission, audience and capacity. The sources below offer context and further reading; they have not validated this playbook.
Goal and fit
Make a clear request to a defined postal audience and measure confirmed responses over a stated window. Decide whether you are renewing a relationship, reconnecting or seeking new supporters before choosing a list.
Consider a small mailing when postal communication suits the audience and someone can maintain addresses, preferences and replies. Existing donor, lapsed-donor and prospect lists represent different relationships and should not share an assumed response forecast.
Count the full costs
- Include writing, design, accessible formats, printing, envelopes, postage, address maintenance and supplier charges.
- Add returned-mail handling, payment processing, reconciliation and staff time. Document how shared creative and setup costs are allocated.
Before you start
- Check the source and permitted use of addresses, current do-not-contact requests and any list-sharing arrangements before selecting recipients.
- Define active, lapsed and prospect groups using explicit dates and history. Keep the groups distinct in both the budget and reporting.
- Approve the exact printed proof, recipient selection, response route, quantities and maximum spend before the print run.
A proposed workflow
- Write one understandable funding request with truthful use-of-funds information and a contact route for questions or preference changes.
- Test readability, the reply envelope or form and any web destination. Offer a route that does not require a smartphone.
- Check a small address sample through the approved process, then provide only necessary information to the mailing supplier.
- Retain the final proof, campaign reference, mailed quantity and actual invoice. Record undeliverable returns separately when known.
- Reconcile incoming gifts across postal and online routes without counting the same gift twice. Keep uncertain attribution visible.
What to measure
- Report confirmed responses per mailed piece with the response window and known delivery uncertainty; this is not an email delivered-message denominator.
- Show gross receipts, cash costs and staff time for each audience group, with refunds and duplicate records handled consistently.
- M+R’s active, lapsed and prospect results are descriptive cohorts. Different reported returns do not isolate the effect of the letter or channel.
Keep the uncertainty visible
Try a bounded experiment
Hypothesis: a clearer reply instruction will reduce avoidable confusion. If the list and budget support it, randomize one change within the same eligible audience, keep timing comparable and define the outcome in advance. Otherwise use a small descriptive pilot and inspect actual questions and returns.
Write the decision rule, spending limit and review date before you begin. Keep negative and inconclusive results. An improvement in fundraising is a separate question from an improvement in the outcomes of the work funded.
Follow through
- Record address corrections and communication preferences before preparing the next list.
- Thank donors through an appropriate channel and reconcile any outstanding payments or questions.
- Review results after the full window, including costs and unwanted mail, before authorizing a repeat.
Watch for
- Mailing more pieces to a poorly maintained list can increase cost without increasing useful contact.
- A web gift after a mailing is not automatically caused by the mailing, especially during overlapping campaigns.
- A favorable gross return can hide acquisition costs, staff burden and later donor losses.

Editorial draft Randomized field experiment
A match offer in a mailed appeal
Past donors to one U.S. civil liberties nonprofit.
Comparison. Recipients were assigned a mailed appeal with a matching offer or an appeal without the offer. The match group includes the different match ratios tested.
Observation window. One month after the direct mail appeal.
| Group | Donors | Gave again |
|---|---|---|
| Assigned a match offer | 33,396 | 2.2% |
| Assigned no match offer | 16,687 | 1.8% |
More recipients gave when offered a match. Donor gifts averaged $0.97 per letter with a match offer and $0.81 without one, excluding matching funds.
Costs. Unknown
Limit. This was one appeal to people who had already given. New donors, online appeals and different match terms need their own evidence.
Share a de-identified result. The form opens a public GitHub issue. Include only aggregate results you have permission to publish, with the comparison and limits. Disappointing and inconclusive results are welcome.
Sources and their limits
These are starting points for your own review. Benchmarks describe particular cohorts; practice guidance and provider experiments answer different questions. No named-charity rating or universal return forecast is supplied.
M+R Benchmarks 2026: direct mail
Describes direct-mail fundraising separately for active donors, lapsed donors and prospects.
Limit. Reported audience results are descriptive, with different starting relationships and costs. They do not prove that changing channels will produce the same return locally.
M+R Benchmarks 2026: glossary
Defines benchmark measures and denominators, including delivered messages, click-through rates, fundraising response and donor categories.
Limit. A shared label does not guarantee that a provider export uses the same definition. Check the numerator, denominator, time window and exclusions before comparing.
AFP: the Donor Bill of Rights
Sets out professional expectations concerning donor information, intended use, acknowledgment, confidentiality and questions.
Limit. These are professional principles, not an effect study or a substitute for applicable law. Read the original; this hub does not reproduce the declaration.
National Council of Nonprofits: gift acknowledgments
Discusses prompt thanks, donor recognition preferences and the distinction between appreciation and formal gift documentation.
Limit. This hub does not generate tax receipts or state legal requirements. Use current official rules and qualified review for your jurisdiction and the particular gift.
