How to choose email verification software

  1. Real-time vs bulk

    Bulk verification (cleaning a list before campaign): NeverBounce, ZeroBounce, Kickbox. Real-time API (verify on signup): Bouncer, Mailgun, ZeroBounce real-time. Most teams need both. Match tool to integration speed and pricing model.

  2. Audit accuracy

    All vendors claim 95%+ accuracy. Test on a known list (100 emails with 20 known-bad) to verify. Accuracy varies by region and ESP coverage.

  3. Plan for catch-all domains

    Catch-all domains accept every email and can't be verified deterministically. Tools flag them as risky/unknown. Decide your tolerance: skip them (lose volume) or send (risk bounces). Pick policy before campaigning.
