Discover, trust, install: FAIR 1.0 is here

A lightweight plugin that protects plain email addresses and mailto links from email-harvesting robots, by encoding them into decimal and hexadecimal entities. Has an effect on the posts, pages, comments, excerpts, text widgets and other filtered content. Works without JavaScript — just simple spam protection.

To see whether all your email addresses are properly protected, use the free page scanner tool.

Other content (like phone numbers) can be protected using [encode] shortcode:

[encode]+1 (555) 123-4567[/encode]
[encode link="tel:+15551234567"]+1 (555) 123-4567[/encode]

Premium Features

• Full-page protection that catches all email addresses
• Hardened protection using JavaScript and CSS techniques
• Improved phone number protection
• Built-in plugin support for ACF, Jetpack, WooCommerce and many others
