A WordPress plugin for blocking certain emails from registering.
Updated August 16, 2025 (version 1.4.6) | How to install or update safely
WP (Wilcosky) Email Blocker is a WordPress plugin designed to prevent users or bots from registering on your website using specific email domains or full email addresses.
Here’s how it works
After installing and activating, go to Settings -> Email Blocker. Check off the predefined list setting, and instantly, 100 known spammy email domains will be blocked from registering. Then you can add more if you’d like. It will log failed attempts, and you can limit the log to the latest 100 blocked emails so that you don’t waste too much space.
Combine this plugin with a good security plugin, and you’ll suddenly be a website security pro.
