How Email Verification Works
The first layer is to perform “syntax” checks; these are essentially tests to ensure that each email address conforms to internationally set email standards (RFC). This checks for correct formatting and that invalid characters are not present in the email addresses.
The second layer is to perform domain name lookups to establish that the domain part of the email address (i.e. the part after the @) actually exists.
The third layer is to check that the domain has been configured to accept emails (MX lookup).
The final layer is to check that the user exists (i.e. the part before the @). We don’t actually send an email to the address, we just initiate a connection to the mail server, retrieve the response and abort the process before an email is actually sent.
No other service that can do this level of email list cleaning.
And unlike other providers, our process is completely automated which enables us to keep the cost very low.
