Verified Email
A Verified Email is an email address that has been confirmed to exist and accept mail — typically via SMTP-level verification or by sending a confirmation message and receiving a positive response.
What is Verified Email?
Verified Email is the foundation of clean email lists. Verification methods range from syntactic (does the address match RFC format?) to existence-check (does the domain have valid MX records? does the mailbox respond to SMTP verification?) to engagement (has this address actually responded to mail?). Each level catches more bad addresses than the previous. Modern email-verification tools (NeverBounce, ZeroBounce, Hunter Verifier) automate these checks at scale. The discipline: verify on capture, re-verify on send, suppress verified-failed permanently.
Why it matters
- Foundation of clean email lists — unverified lists have 10-30% deliverability problems.
- Layered verification (syntax + existence + engagement) is stronger than any single check.
- Failed verification should auto-suppress — re-trying bad addresses damages sender reputation.
Use cases
- Capture-time verification. Form submission verifies the email before saving the lead.
- Pre-send verification. Verification before send catches addresses that went bad since capture.
- Periodic list cleaning. Scheduled re-verification removes addresses that have gone stale.
How turgo helps
turgo runs multi-layer email verification at capture and at send — catching bad addresses before they damage deliverability, and auto-suppressing verified-failed addresses.
