About
Add-on for Gravity Forms to create a Blacklisting of specific emails or domains for the Email input field to throw a validation error or mark as spam.
What It Does
Gravity Forms Email Blacklist is an add-on for Gravity Forms that lets site administrators block submissions containing specific email addresses or entire email domains on form email fields. Blocked entries can be flagged as spam or rejected outright with a validation error. It is a focused, single-purpose tool aimed at filtering unwanted signups and form spam at the email layer.
Who It's For
This plugin is best suited for site owners who already rely on Gravity Forms for lead capture, event registration, course enrolment, or membership applications and want to keep junk or competitor email addresses out of their list. It works well for small to medium operations where a curated blacklist of recurring offenders is enough to keep form noise down.
Who Should Skip It
Anyone not using Gravity Forms should skip this plugin since it has no functionality without that parent plugin. Sites facing high-volume bot submissions should also look at a broader anti-spam solution rather than relying solely on email filtering.
The Bottom Line
Gravity Forms Email Blacklist does one thing, and recent update activity suggests it does it reliably for the 10,000 sites currently running it. With a 78.31 overall quality score and no public support history, it is a sensible pick for Gravity Forms users with a clear blacklist strategy, but those needing heavier spam defences should consider Gravity Forms Zero Spam or Maspik instead.
