Overview
The Email Blacklist Add-on for Gravity Forms was built to help block submissions from users with generic or competitors email addresses. Prevent the user from processing the form and stop non-qualified leads from being collected.
This plugin allows site admins to create a list of domains that if used in an email field on a Gravity Form it will cause a validation error and block the submission. A default email blacklist and validation message can be created to use across all email fields. These default settings can be overridden on a per email field basis.
Global settings can be added on ‘Forms’ > ‘Settings’ > ‘Email Blacklist’. To add settings to an individual email field, select the field and navigate to the ‘Advanced Settings’ tab.

It works!
by @anansi.pro·1 year ago
GF 2.8.18 , WP 6.5.5, PHP 8.2.23. WPE hosting.
It even works wih 3.5 thousand rules in a single string for blacklist of disposable email domains.
PHP 8

Uncaught TypeError: explode(): Argument #2 ($string) must be of type string, array given in (original path removed for privacy reason)/plugins/gravity-forms-email-blacklist/includes/class-gfemailblacklist.php:259
I guess it’s because of PHP 8. This shouldn’t happen at all, please fix it.

Great Addon, outstanding support!
by redactuk·2 years ago
This Addon for Gravity forms does exactly as advertised.
On top of that, when I had an issue recently the support response via these forums was outstanding. Probably the best I’ve ever received via this site. Well done guys!
Need support for blocking domain names with wildcards, not just TLDs
by ericscoles·2 years ago
Still evaluating, but one key deficit is that wildcard support doesn’t seem to extend to domains, only to TLDs. Why that matters: We routinely get hammered by exploit probes using example.* domains, which blow past reCAPTCHA without slowing down. (Presumably they use example.* on the assumption it will be allowed to pass through filters.) It’s a massive inconvenience for the people receiving our forms. (Yes, I realize this would also block submissions from vuln scanning suites.)
Great plugin. Easy to setup. No more spam!
by Matt Rock·3 years ago
The ability to use wildcards is a super feature. No more spam from the .ru domain! Thanks so much for this.
