How email verification works
There are several layers to the verification process.
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.
More than just verification - thorough cleansing!
This is what makes our service truly unique. We not only
do the email address verification process, we do so much
We can repair your data to fix common typos e.g. where
billyd@hotmaik.com becomes billyd@hotmail.com and run
the repaired address through the next layer of checks.
We report back to you the results of each layer of the
verification process, showing which email addresses have
You can define custom rules to remove certain types of
email address e.g. all addresses containing “support@” or
“info@” etc. or all addresses for a certain domain e.g.
“gmail.com”. The possibilities are almost endless!
We will also remove duplicates from your list (de-dupe)
to ensure you do not email the same contact more than once.
There is 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. Go on - try it now, click the button below to get
