This plugin will add a shortcode that can be used to stop spambots from harvesting emails entered into your WordPress editor while creating pages or posts.
To use, just wrap your email address in the [email] shortcode:
[email]you@yourdomain.com[/email]
The result will be a hyperlinked email address that can be clicked on to send email.
The plugin uses WordPress’s built-in antispambot() function which converts email address characters to HTML entities which are not read by spambots, but can be viewed properly in the browser. For more info on the WordPress function read up in the Codex – https://codex.wordpress.org/Function_Reference/antispambot

Spamex provides a shortcode to obfuscate email addresses and phone numbers in HTML. This protects them from scraping bots while staying readable for users.
<h3>Examples:</h3>
<ul>
<li><code>[spamex email="name@domain.tld" key="secret"]</code></li>
<li><code>[spamex phone="+1!123!456"]</code></li>
</ul>
<h3>How it works:</h3>
Email: 
– The <code>key</code> is injected between domain and TLD. 
– Example: <code>name@domain.secret.tld</code> (key is hidden via CSS)
Phone: 
– Format must be: <code>prefix!middle!suffix</code> 
– The <code>middle</code> part is replaced by random digits. 
– Example: <code>+49!123!456</code> → <code>+49123XYZ456</code>
In both cases, the <code></code> part is hidden using CSS and only fools bots.
<h3>Usage</h3>
<h3>Email obfuscation:</h3>
[spamex email=”test@example.com” key=”protect”] 
test@example.protect.com
[spamex phone=”+49!123!456″] 
+49123984456
Use exactly two ! to split number into three parts.
