Hi Jezweb,
I have not used gravity forms but it should work.
Ask the following question to the Gravity Forms support.
Does your plugin use the is_email() function to validate email addresses ?
If they say yes then this plugin will work with gravity forms.
I checked with gravity forms support, under 10min for a reply which was impressive.
Gravity Forms does not use is_email() but it does perform validation on emails entered in the Email field.
If they do not use the is_email() function then this plugin will not work with it.
However if you already have a gravity forms license you can install this plugin and check it yourself using any of the following email addresses
user@example.com
ab@gmail.com
x.y.z@yahoo.com
