Frequently Asked Questions
What is a good email bounce rate?
+
For B2B outreach, keep your bounce rate under 2%. Anything above 5% puts your sender reputation at serious risk. Email verification before sending is the most effective way to stay below this threshold.
What's the difference between email verification and validation?
+
Email verification checks if a mailbox exists and can receive mail (via SMTP handshake), while validation checks format and syntax (e.g., is it a properly formed email address). Verification is more thorough but requires a network check; validation can be done instantly on the client side.
How often should I verify my email list?
+
Verify before every major campaign. For ongoing sequences, quarterly verification is sufficient. B2B email data decays at roughly 30% per year due to job changes, so lists older than 3 months should always be re-verified.
