How to use email checker
What is an email checker?
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 exists on the SMTP server.
Depending on the provided email address, we might apply extra-checks on a per basis.
