How to stop forms from being sent to the wrong email

How many orders can be lost if a visitor enters their email address incorrectly?
And how many re-registrations can be made if the user enters an email that doesn't exist?

To avoid this, we added the 'Show email existence alert when filling in the field' option to the Anti-Spam plugin for WordPress. This option will show a visitor in real-time if they made a typo in their email address or if it does not exist. 

The option is available in the Data Processing section of Advanced Settings and enabled by default. It works with the registration form, comments, and Woocommerce order form.

How it works

When a user submits a form (such as a comment or registration form) on your website, CleanTalk's system instantly checks the validity of the provided email address. If the email address is found to be non-existent or invalid, the user will see an immediate alert. 

How it looks

An email is existent.

An email is non-existent.
