Email deliverability checker
Run the deeper check: address syntax, domain health, mail routing, disposable risk, role-account risk, mailbox response and catch-all behavior when the receiving server allows it.
No email is sent. Some providers intentionally block SMTP verification, so mailbox and catch-all signals can be unknown.

Deliverability is not a binary fact
A valid-looking address can still bounce, and an SMTP server can accept a probe without guaranteeing future delivery. EmailValidly keeps each signal separate so you can see what was proven and what remains uncertain.
Why catch-all domains are risky
Catch-all mail servers accept messages for many or all addresses at a domain. That makes a specific mailbox harder to verify. We flag this separately rather than treating every accepted SMTP response as proof of a real inbox.
