Sending E-Mail to validate User Sign-up

In on of our last tutorials we covered how to verify that a user’s email address is formatted correctly as well as verify that it goes to a valid domain name. That is great, but still not a great way to make sure a user actually owns or uses that e-mail address. This tutorial will walk you through one method of sending the user an e-mail upon signing up that gives them a link to activate their account.
