Is there a reason why many of my sites (customers) need to re-verify the form email address in order for the contact form to stay active and functional? I have had many complaints from my customers that there form on the site stops working and indicates an error message (see attached image capture).
This is very annoying and many of my customers have complained that they must have lost many prospects towards there business because of this issue.
Why do we need to re-verify the email address so often??
