What is the Email Verifier?
A tool that checks any email address for the problems that cause bounces: malformed syntax, a domain with no mail server, and a mailbox that does not exist. It probes the mail server live, without sending anything.
No sign-up, no API key. Paste an address and get a verdict in seconds.
What We Check on Every Email
Each address runs through three live checks: format, mail server, and mailbox. Every result shows you exactly why it was scored the way it was.
Every verification returns:
- Syntax (RFC 5322 format check)
- MX records (does the domain accept email)
- SMTP mailbox probe (does the inbox actually respond)
- Risk level (low, medium, or high verdict)
- Response time (speed of the live check)
Why Verify Before You Send?
-
Reach real inboxes
Skip addresses with no mailbox so your message lands in front of a real person.
-
Protect sender reputation
Bounced emails hurt your domain reputation. Clean lists keep deliverability high.
-
Save outreach budget
Cold email tools charge per send. Verify first so you only pay for addresses that exist.
-
Catch dead domains
Spot domains with no mail server before they bounce your campaign.
