# Double Opt-In

## In this article, you will learn how to enable and edit the Double Opt-In mechanism on the Apifon platform.

Double Opt-In is an additionalconfirmation step that helps you reduce the chance of spam or misspelled destinations (mobiles, emails) on your list.

When the Double Opt-In is enabled, after a subscriber clicks Submit on a [Signup form](https://apifon.sharepoint.com/:f:/r/sites/RevenueTeam/Shared%20Documents/%F0%9F%93%9A%20Useful%20Info?csf=1&web=1&e=QZBwjR), they will receive a message (SMS and/or Email) **to verify their data and confirm their wish to subscribe** to your list.

 Each subscriber that has not completed the extra confirmation step is displayed on your list as **Unconfirmed** and will not be able to receive any communication from you.
