How to use our email checker?
What is an email validator?
How does an email verifier work?
Email checker proceeds with several checks to determine if an email address is valid:
- The email address must be well formed (e.g. {firstname.lastname}@{domain}).
- It should not be generated by a disposable email service (such as
mailinator.com
). - The MX records should be present on DNS.
- An SMTP server should run for the domain.
- A mailbox with that email address should exist on the SMTP server.
Depending on the provided email address, we might apply extra-checks on a per basis.
