This free email verification tool lets you verify if an email address is valid, properly formatted and really exists.
This tool works as SMTP Server: MX-Records are extracted from a DNS Server.
Then the tool connects to SMTP servers and simulates the sending of a message.
For some domains you can't verify whether the address is good or not, because their mail servers don't cooperate.
The answer is NO. We respect your privacy, and do our best to protect data used by this tool.
