Message Tester

A simulated donor panel reacts to your appeal before it goes out.

A youth program could learn its appeal read as guilt-heavy and soften it before sending.

How it works

Three calm steps

  1. 01

    Tell it about your work

    Share your appeal, subject lines, and who you're writing to. It learns your programs, your voice, and your numbers once, then keeps them close.

  2. 02

    Ask for what you need

    Ask for reactions from a simulated panel of donors. Plain words are fine; no prompts to master.

  3. 03

    Review, then share

    What landed, what confused people, and one suggested rewrite. Nothing goes out until you've read it and made it yours.

Panel read · Year-end appealIllustrative sample

First-time donors: moved by the story, unsure of the ask

Longtime donors: want to see last year's results

Line that lost people: "Every dollar counts"

Suggested: name what $50 does, in one sentence
