Email Address Encoder

外掛說明

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

  3. Use the “Page Scanner” under Settings -> Email Encoder to test if your email addresses are protected.

常見問題集

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.

I've used this plugin for several years on many websites.

Free version only walks through post content, doesn't touch widgets. This one does https://wordpress.org/plugins/email-encoder-bundle/ and also this js solution seems more proof than replacing characters with unicode symbols
