Hypothesis
This experiment tested whether shifting the GiftAssist prompt from functional fee language to mission-focused language—and replacing “Add” with “Help”—encouraged more donors to cover fees without reducing donation completion.
Duration
7 days
Timing
July 21–28, 2026
Audience
Nonprofits using eligible Standard Donation Forms with GiftAssist enabled and the default, non-customized fee-coverage prompt.
Group split
Supporters were split evenly: half saw the current default copy, and half saw the mission-focused version. Every other form element stayed the same.
What this means for you
Keep your current fee-coverage copy with confidence. 'Add' and 'Help' performed the same, so Bloomerang's sticking with 'Add' as the default.
Key results
The mission-focused version produced a 62.42% fee-coverage rate, compared with 61.36% for the current copy. Conversion was nearly identical. Both measures increased slightly, but neither difference was statistically meaningful.
Segment insights
The test included organizations using eligible Standard Donation Forms—including text-to-donate—with GiftAssist enabled and the standard default prompt.
Conclusion
The tested wording didn’t produce a clear lift in fee coverage or conversion, so the current copy remains the default.
