Only the email address. That's right, unlike other providers we don't ask you to provide the users: first name, last name, location and Ip address. 


You can include as much data as you like in your list and we will amend our results in the end columns after your data. 


But our general advice is to just include a unique identifier number and the email addresses in your file. 


Example: 


Unique identifier number
Email address
001[email protected]
002[email protected]
003[email protected]


We will then add your verification results, on to your file which will look like the example below.
