Email verification is the process of validating that an email address is real, deliverable, and safe to contact before sending outreach. For B2B cold email, unverified addresses produce bounces that damage sender reputation — one of the fastest ways to get an outbound domain permanently flagged as spam.
Email verification is the multi-layer technical process of confirming that a B2B contact email address is deliverable, belongs to an individual (not a role inbox), passes MX record checks, and has not previously generated bounces or spam reports.

Hunter.io and ZeroBounce each have different data sources and validation methods. An email that passes Hunter.io might fail ZeroBounce's SMTP check, or vice versa. Requiring both creates a higher confidence signal — the dual-pass approach eliminates the false negatives that cause bounces.
Failed emails are marked with a failure reason (invalid domain, catch-all, role-based, globally suppressed) and excluded from the outreach queue. If you imported them via CSV, you can review the failure reasons in the prospect list. AI-discovered prospects are only inserted if they pass full verification.
