Free Email Verifier Extension 作者： E-Tech

Free Email Verifier by EcomTech — verify any email address with one click, right from your browser.

This free email verifier performs real SMTP mailbox checks, MX record validation, and disposable email detection in under a second. No signup, no credit card, no expiring credits.

═══ WHAT IT CHECKS ═══
✓ SMTP mailbox check — connects to the destination mail server to confirm the mailbox exists, not just that the domain accepts mail
✓ Disposable email detection — 150,000+ throwaway domains (Mailinator, Temp-Mail, Guerrilla Mail, 10MinuteMail, and more)
✓ Role-based filter — flags generic addresses (info@, support@, admin@, sales@, contact@)
✓ MX & DNS validation — resolves MX records, falls back to A records, detects tarpitting servers
✓ Catch-all detection — flags servers that accept anything as "risky"
✓ Sub-second results — most checks complete in under 800ms

1. Click the toolbar icon to open the verifier
