Donor Messaging FAQ

Can I test email fundraising appeals?

Yes! Paste your full email copy including subject line. Test different emotional appeals, asks, and urgency levels.

How do political breakdowns help fundraising?

Different causes appeal differently across political lines. See how Democrats, Republicans, and Independents each react to your messaging.

Is this better than donor list A/B testing?

It's complementary. Use SimAudience for fast pre-send optimization, then validate with real donor A/B tests. This way you don't waste half your list on a weak message.

Can I test year-end giving appeals?

Absolutely. Test urgency messaging, matching gift appeals, impact stories—any fundraising approach.

Is my appeal content kept private?

Yes. Your content is only used for testing and deleted after 30 days. We never share your messaging.

Can I test social media fundraising posts?

Yes! Use the platform dropdown to select Facebook, Instagram, or any other platform where you fundraise.

Important: SimAudience uses simulated audience modeled on demographic data. This is a synthetic simulation, not a survey of real donors. Results should be used for directional guidance only.
