Frequently Asked Questions

What nonprofit teams ask us before they start.

Book a demo

  1. How is this different from the propensity models we already have?

    Those models score big cohorts on past giving. Chorus works at the individual level. We read the draft you’re about to send and what’s in the news today, then decide for each supporter who should get it.

    How the pilot works

  2. How much work is it to set up?

    Usually one 30-minute meeting. You give us read-only access, and we handle the data engineering and record matching. The Study can start any time, even before a platform migration.

  3. Will we need more production capacity?

    No. Start with the sends you already make and let Chorus decide who gets them. If it suggests new variants, they’re drafts your team approves first.

  4. How do you model supporters without their personal data?

    We never ingest or store PII. Chorus works from your messages and each anonymous ID’s engagement and giving history, kept isolated, never pooled, and never used to train anyone else’s models.

  5. Is our list big enough?

    If you have about 150,000 active email or SMS subscribers, yes, and bigger files see more lift. Below about 50,000, good basic practice gets you most of the way.
