 * Hi,
    Is there any PHP function/hook that I can use to implement an extra email
   validation? Basically I would like to add certain rules that prevent some type
   of SPAML emails that I’m getting. So, besides checking if an email is valid, 
   I would also want to check if it complies with some extra rules. And I would 
   like to do this from the theme functions.php file so that I can always keep the
   plugin updated. I don’t want to use the CAPTCHA and I already have the double
   opt-in active. Thanks for a great plugin!

 * [@pirenko](https://wordpress.org/support/users/pirenko/), why don’t you use GoodBye
   Captcha for this?
    The MailChimp for WordPress team recommends to use it for 
   such situations.

 * [@erik](https://wordpress.org/support/users/erik/) – thanks for sharing! I did
   not know about this one. I’ll give it a try and will let you know if I still 
   have trouble. Cheers!
