Description
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]

FAQ
-
What does this plugin do?
-
This plugin searches for email addresses using WordPress filters like
the_content
,widget_text
and others. Found email addresses are encoded using decimal and hexadecimal HTML entities, which obfuscates the email addresses to protect it from being read by most email-harvesting robots.Alternatively, you can use the
[encode]
shortcode:[encode]+1 (555) 123-4567[/encode]
-
How can I make sure the plugin works?
-
You can use the “Page Scanner” found under Settings -> Email Encoder to see whether all your email addresses are protected. Alternatively, you can manually look at the “page source” of your site.
Please note: Chrome’s Developer Tools, Safari’s Web Inspector and others automatically decode decimal and hexadecimal entities. You need to look at the “plain HTML source code”.
-
How can I filter other parts of my site?
-
This guide will help you encode all email addresses that aren’t caught.
