One of the most important factors in e-mail list creation is double opt-in. A confirmation link is sent to the e-mail address entered by the user who wants to become a member of your site. The person who clicks on the confirmation link becomes a member of your site, thus their e-mail address gets confirmed.

The Double Opt-in process, which is one of the most important ways to perform the e-mail consent process, is the name of the e-mail sent to the users who want to subscribe to your business in order to verify their identity. The recipient will be added to your business’s e-mail list by clicking on the link in the e-mail.
