Email Verifier
Check syntax and domain delivery signals.
Email verification checks that an address is syntactically valid and that its domain publishes working mail records. It cannot confirm a specific mailbox exists — most providers deliberately refuse to answer that, so any tool claiming certainty is guessing.

How Email Verifier works
What it does
Check syntax and domain delivery signals.
What you get
Syntax and mail-routing checks; these do not prove a mailbox exists.
Live data sources
The target is sent to a network provider. Results include their source; timeouts and unavailable data are clearly marked.
What if a check cannot finish?
Confirm your input and try again. A timeout, blocked request, or unavailable provider is not proof that a domain is broken. Internet measurements and third-party services have limits.
Email Verifier — frequently asked questions
Can you tell me if this mailbox really exists?
No, and be sceptical of tools that claim they can. Most mail servers accept all recipients at connection time and bounce later, specifically to defeat address harvesting.
What does a valid result actually mean?
The syntax is correct and the domain is configured to receive mail. It is a filter for typos and dead domains, not a delivery guarantee.
Will this reduce my bounce rate?
It removes malformed addresses and dead domains, which is a real share of bounces. It will not catch a correctly formed address at a live domain that was never a real mailbox.
