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 <a href="https://encoder.till.im/scanner?utm_source=wp-plugin&utm_medium=readme" rel="nofollow ugc">page scanner</a> tool.
Other content (like phone numbers) can be protected using <code>[encode]</code> shortcode:
<pre><code>[encode]+1 (555) 123-4567[/encode]
[encode link="tel:+15551234567"]+1 (555) 123-4567[/encode]
</code></pre>
<h4>Premium Features</h4>

Email Address Encoder


This might work with page or post content, but does not with widgets. I can't recommend using this and suggest to use the plugin "Email Encoder" by Jannis Thuemming instead, since that does the job out of the box.
