  • Not a verifier

    This is not a verifier of email in real time. Don't waste your time if that is what you are looking for.

  • Really Good plugin for contact form 7

    I was very frustrated by getting spam bot emails from my website's contact forms. Then I realized the bots are not using real emails in the contact form. So filtering invalid emails can solve the problem I taught and it really did. Now I only get valid and important emails and messages from my website.
