Part of Donor acquisition: judging a channel by retained donors, consent and capacity
Comparing donor acquisition tools on the jobs they actually do
Six donor acquisition tools compared on the same task: finding new donors, proving cost per retained donor, and leaving with your data intact.
What to take away
Donor acquisition tools look alike in a demo. Compare them on the jobs you already run: finding new donors, proving cost per retained donor, and leaving with your data intact.
- Run the same task in every donor acquisition tool before you compare price: one import, one segment, one appeal, one export.
- Price the exit, not the subscription. Migration labor is the cost that surprises boards.
- Ask for cost per retained donor at month twelve, not cost per lead at week one.
- Check vendor claims against the FTC advertising substantiation policy standard: objective claims need a reasonable basis before they are published.
- Confirm Canadian receipting and consent rules with the CRA or a charity lawyer, not with a sales deck.
The six donor acquisition tools: Bloomerang, Neon CRM, Little Green Light, Givebutter, Mailchimp and HubSpot
These are the platforms most small and mid-size charities shortlist. Each is a real product, each prices differently, and each wins on a different job. Figures below are typical as of 2026 and move with contact counts, modules and seats.
Bloomerang is donor CRM first. It suits a shop with one or two fundraisers who want retention dashboards and automated thank-you flows without a consultant. Pricing is subscription tiers by contact count, quoted on request; small-shop plans typically run about $100 to $400 a month.
Neon CRM bundles CRM with forms, events and peer-to-peer pages. It suits organizations running walkathons and giving days who would rather not stitch three vendors together. Tiers are published, with entry packages commonly listed near $99 a month billed annually.
Little Green Light is the low-cost donor CRM. It suits all-volunteer or single-staff development offices with tight budgets and simple needs. Flat subscription, no per-contact scaling, commonly around $45 a month for a few thousand constituent records.
Givebutter is free-to-start fundraising with events, auctions and peer-to-peer. It suits campaigns testing a new audience where speed matters more than deep reporting. No subscription; a platform fee on gifts, with a tip-cover option, and card processing typically about 2.9 percent plus 30 cents a gift.
Mailchimp handles email and audience segmentation, not donor records. It suits teams sending appeals and newsletters who keep gifts in a separate system. Free tier up to 500 contacts, then monthly pricing by contact count, commonly from about $13 a month.
HubSpot is the choice when marketing and donor data must sit in one place. It suits larger nonprofits with a marketing hire who will configure workflows. Free tier, then per-seat and contact-tier pricing, with Starter seats commonly around $15 to $20 a month.
For the acquisition program itself, start from donor acquisition and pick the tool that fits the job you already run.

Run one equal task across all six
Equal trial task steps
- Import 2,000-row file with duplicates
- Build segment of lapsed donors who gave twice
- Send one appeal
- Export result with gift dates and consent flags
- Time it and note who could do it
- Ask vendor to price whole thing
Time it. Note who on your team could do it without help. Then ask each vendor to price the whole thing, including the migration.
| What to record | Why it decides the purchase |
|---|---|
| Setup hours by role | Setup is where the subscription price stops being the real price |
| Export format and completeness | If consent flags do not export, your CASL records live in someone else's database |
| Duplicate handling | Two records for one donor means two appeals and one annoyed supporter |
| Support response time observed | Ask during the trial, not after signing |
| Total cost to exit | Export, cleanup, retraining, and the months of reduced output |
| Gift notes and consent dates in the export (test on Bloomerang and Little Green Light) | These are the fields charities lose first in a migration |
| Free-tier export limits (test on Mailchimp, HubSpot and Givebutter) | Confirm export works before you load real donor data |
Price the exit before you price the plan
Ask each vendor for a full export in a documented format, then open it in a spreadsheet yourself. If the export loses gift notes or consent dates, that gap becomes labor on your side.
Total cost is subscription plus setup plus staff hours plus support plus migration out, divided by the number of retained donors you expect in year one. Put your own figures in:
- Annual cost = subscription + setup + (staff hours x loaded hourly rate)
- Cost per retained donor = annual cost / donors still giving at month twelve
A typical example: $100 a month, $1,500 of setup and 40 staff hours at $30 is about $3,900 in year one. Across 120 donors still giving at month twelve, that is roughly $33 per retained donor.
The GOV.UK open standards guidance makes the portability case for public bodies: open formats reduce supplier dependence. Treat it as a prompt, since it governs UK public-service work, not your charity.
Check the vendor's claims, not the demo
The CISA software acquisition fact sheet asks buyers to look at development practice, supply-chain exposure, deployment and vulnerability management. Add those answers to the purchase record as checks, not as approval.
When a vendor says a tool "doubles donor retention," ask for the study, the sample and the date. If there is none, treat the number as a hypothesis you test yourself.
Design the test so the result means something
The NIST experimental design selection guidance starts with the objective and the practical constraints. That is the discipline here: decide what you are measuring before you split the audience.
- Pick one metriccost per retained donor at month twelve
- Split the appeal audience randomly, not by gift size
- Run both arms for the same number of days
- Freeze the copy and the gift array across arms
- Record the tool version, plan and date
- Write the stop rule before you start
Common questions
What if two tools score the same?
Pick the one whose export you can read without help. Portability decides ties, because the second purchase is the one that costs you the migration.
How long should the trial run?
Long enough to see one full appeal cycle and the thank-you follow-up, usually four to six weeks. A two-day demo shows the interface, not the labor.
Which of the six is cheapest to start?
Little Green Light runs a flat fee, commonly about $45 a month. Givebutter charges no subscription and takes a platform fee on gifts instead. Neither one replaces a full CRM with events and marketing built in.
Do we need a lawyer for the consent records?
For Canadian programs, name the authority and get advice: CASL consent, PIPEDA and Quebec Law 25 set rules that vary by province and by how consent was captured. A qualified charity lawyer or the CRA can confirm what your records must show.
