Double opt-in

This feature is enabled by default and is used to verify your customers by sending them a confirmation email. Verifying email addresses can help you combat fraud attempts and fake email addresses. 

Double opt-in is not available in every template (e.g. Redeem a Code). If you can't see it in your template settings, choose a different template instead (e.g. Collect Subscribers).

You will find the double opt-in feature in the Settings of your landing page.

Only unique emails

If the user tries to sign up using an email address that has already been registered, he/she will receive an error notification that can be customised in Pages tab.
