With this feature, you can control what email domains can be sent test emails from within Knak.
In Admin > Settings > Editor, you will be able to edit the list of allowed Test Email Domains. Add multiple domains by adding a comma and a space between each domain.
When sending a test email, it will show the user the allowed email domains:
Any email address with an unacceptable domain will not be allowed to be sent a test email.
