Questions & answers about email checker

Everything you need to know about how and why checking email addresses.

Email checker is a free, easy to use and simple tool. Just enter the email address and click on "Verify". We will then proceed with several checks to verify the email address and flag it as valid or invalid.
Email checker is a free tool to verify anyone's email address. It validates that the email address is well formed, not from a disposable email service and that the email address is technically well-configured (MX records are present, SMTP mailbox replies successfully). In case we detect something wrong, the email address will be flagged as invalid.

Email checker proceeds with several checks to determine if an email address is valid:

  1. The email address must be well formed (e.g. {firstname.lastname}@{domain}).
  2. It should not be generated by a disposable email service (such as mailinator.com).
  3. The MX records should be present on DNS.
  4. An SMTP server should run for the domain.
  5. A mailbox with that email address should exists on the SMTP server.

Depending on the provided email address, we might apply extra-checks on a per basis.

Email Checker is totally free to use. Mailmeteor makes it available to anyone interested in checking an email address and make sure you won't get a bounce.
