Mightycause vs.
Sponsor A Purpose
Discover why nonprofits choose Sponsor A Purpose
A Mightycause alternative where the CRM is not the upsell
Mightycause advertises a zero cost feature suite at $0 per month. The fundraising pages are genuinely free, but the donor CRM is not: their own support centre says Contacts only appears if you have the necessary subscription plan, and automated emails, text-to-give, offline donation import and every integration sit in the same paid tier. On top of that, each gift carries a 7.9% + $0.30 transaction fee. Sponsor A Purpose charges 0% platform fees, passes through Stripe at 2.2% + $0.30, and puts the CRM on the free tier. If you are looking at Mightycause alternatives, check what the free plan includes before you compare anything else. Theirs does not include the donor database.

Cost and what you get free
Both platforms are free to start, so the question is what free actually covers. Mightycause takes 7.9% + $0.30 out of every gift, and their own support centre says the Contacts CRM only appears if you are on a paid subscription plan.

Donor CRM
Mightycause Contacts handles records, filters and segments well once you are paying for it. What it does not carry is households, tasks and follow-up reminders, or the giving metrics and stewardship prompts that tell you who to ask next.

Giving and payments
Checkout is close to matched: recurring giving, Apple Pay, ACH and automated receipts on both sides. The gaps run in both directions. Google Pay, DAF giving and employer matching gifts are ours; peer-to-peer and event ticketing are theirs.

Communication and automation
Their automated emails are single-toggle and fire based on how someone interacted with a Mightycause page, which is triggered email rather than a multi-step journey. Text-to-give is theirs outright, on unlimited keywords.
| Feature | Sponsor A Purpose | Mightycause |
|---|---|---|
| Automated emails | Sponsor A Purpose: yes | Mightycause: yes |
| Prebuilt donor journeys | Sponsor A Purpose: yes | Mightycause: no |
| Text-to-give | Sponsor A Purpose: no | Mightycause: yes |
Grants
Mightycause does no grant seeking. Their Matching Grants feature is a match campaign, where a sponsor pledges to match gifts to create urgency, which is a different thing from finding and winning funders.
| Feature | Sponsor A Purpose | Mightycause |
|---|---|---|
| Grant discovery on IRS 990 data | Sponsor A Purpose: yes | Mightycause: no |
| AI grant writing | Sponsor A Purpose: yes | Mightycause: no |
| Grant deadline and pipeline tracking | Sponsor A Purpose: yes | Mightycause: no |
| Post-award spend tracking | Sponsor A Purpose: yes | Mightycause: no |
Volunteers
Both platforms list volunteer opportunities. Only one schedules shifts and tracks hours, and volunteer management is a $29 a month add-on for us rather than a subscription tier.
| Feature | Sponsor A Purpose | Mightycause |
|---|---|---|
| Volunteer opportunity listings | Sponsor A Purpose: yes | Mightycause: yes |
| Volunteer scheduling and shifts | Sponsor A Purpose: yes | Mightycause: no |
| Volunteer hour tracking | Sponsor A Purpose: yes | Mightycause: no |
Services and support
Mightycause support is genuinely well reviewed, with named project managers on giving day campaigns, and that is not in dispute. The difference is the work around the software: website design, hosting, managed Google Ads and consulting, which we sell as paid services.
| Feature | Sponsor A Purpose | Mightycause |
|---|---|---|
| Appointment scheduling | Sponsor A Purpose: yes | Mightycause: no |
| Website design and hosting (service) | Sponsor A Purpose: yes | Mightycause: no |
| Growth consulting (service) | Sponsor A Purpose: yes | Mightycause: no |
| Managed Google Ads for nonprofits (service) | Sponsor A Purpose: yes | Mightycause: no |
| Nonprofit-only focus | Sponsor A Purpose: yes | Mightycause: yes |
