Hi all, I am wanting to add email validation to my Gravity Forms to prevent users from submitting an email address having an ESP domain (gmail, yahoo, msn, etc.) or a bogus domain (test, email, etc.).
I found a code snippet to add a list of these domains myself, but it seems like using an add-on/service would be a more comprehensive approach. Any suggestions?
Thanks in advance
How about this free snippet from Gravity Wiz:

Chris always has the best recommendations. 
We’ve since turned that snippet into a full-featured plugin. It specifically checks if emails are real and provides the option of checking for (and blocking) email providers like Gmail and Yahoo, or bogus domains.
