Hook to disallow disposable emails

Hi @rick111,

To disallow specific email domains in Subscribe2, you can use the s2_validate_email filter hook. This hook allows you to perform custom validation on an email address before it is accepted into the subscription list.

By using this filter, you can check the email domain against your own array of disallowed domains and return false to block the subscription if a match is found.

While we don’t provide custom code implementation, you can find more information on using WordPress filters in the official developer documentation.

I hope this points you in the right direction!
