When you think of email validation you might think about sending out a mass email and counting the bounces. However,we do not ever send out an actual email to the contacts in a database. The first step in validation all happens via SMTP testing, MX records, and domain check electronically. It is like a server to server handshake. When that happens we get responses defined in certain codes. These codes indicate if the email address exists, if it will accept it, etc. In simple words, it translates to a hard bounce or soft bounce. We take that information and use it to create a status report, allowing us to visualize the data.
