Email Validator
Validate an email live
Syntax, MX, disposable, SMTP response — the same pipeline used before sending.
Try a real mailbox first, then a fake one to see SMTP rejection.
Email Validation
Validate an email live
Real-time SMTP probing catches invalid, disposable, and risky addresses — so every send lands where it should.
- SMTP-level verification, not just format checks
- Detects disposable, catch-all, and bounced addresses
- Bulk CSV validation to clean lists before import
