  2. Pro Features

Restrict to Domain

Whitelist a domain to send the form from.

Heads Up! This is a PRO feature. You must have an active membership to use this feature.

You can restrict the form from sending only through a whitelisted domain. This will potentially reduce spam attacks. So even if someone else got the access key, they cannot send emails to you. Only emails from your website are counted.

To enable this feature, Please contact support.
