MisarMailQuick Answer
The process of validating whether an email address is real, deliverable, and not a spam trap before adding it to your list.
Email verification checks: if the domain has valid MX records, if the mailbox exists (SMTP verification), and if the address matches known spam trap patterns. Verifying your list before import reduces hard bounce rates and protects sender reputation. Best practice: verify all new imported lists and re-verify inactive contacts older than 12 months. MisarMail includes built-in email verification for all contact imports, with per-contact verification via the Lead Finder.
A permanent email delivery failure due to an invalid, non-existent, or blocked email address.
