Email Verifier
Validate an address: syntax, domain MX, role/disposable, live mailbox probe.
Frequently asked questions
How does email verification work?
It checks the address syntax, confirms the domain has MX (mail) records, flags role and disposable addresses, and can optionally probe the mail server with an SMTP RCPT command to see if the mailbox is accepted.
Why is the SMTP probe sometimes inconclusive?
Many mail servers deliberately accept all recipients (catch-all) or greylist unknown senders to prevent exactly this kind of probing. An inconclusive result does not mean the address is invalid.
What is a role address?
A role address such as info@, support@ or admin@ belongs to a function rather than a person. They are valid but often unsuitable for marketing lists.
Does this send an actual email?
No. The optional probe only opens an SMTP conversation up to the RCPT step and then disconnects — no message is ever delivered.
