How’s email verification different from email validation?
Email validation is a process that checks if an email address is valid. It happens when a “ping” is sent from one server to another. A pingback from the latter informs us the email address we are validating exists, is being used and accepts incoming messages. The validation happens between servers, meaning you don’t have to send an actual email. What email validation doesn’t tell us is whether there’s an actual person behind the first part of the email address: it only checks the domain part — the one that comes after @.
That’s where email verification comes in. Unlike validation, it’s not a single step (a digital ping to the server) but rather a series of steps. And unlike validation, verification allows you to make sure that an actual living person is on the other side — not a bot, a spammer or a disposable account (i.e. created for a single use).
