Obfuscate your email address by using a simple shortcode. Because the obfuscation is purely done in CSS, the email address remains readable for screen reader software.
Usage
Email address only:
<pre><code>[css-email-obfuscator]you@example.com[/css-email-obfuscator]
</code></pre>
Clickable email address:
<pre><code>[css-email-obfuscator mailto="yes"]you@example.com[/css-email-obfuscator]
</code></pre>
Clickable email address with custom link text:
<pre><code>[css-email-obfuscator mailto="yes" email="you@example.com"]Contact me[/css-email-obfuscator]
</code></pre>

[email-obfuscate email=”bob@example.com” link_title=”Email Bob!”]
*Setting custom link title attribute”

Usage from a template or plugin
Below is a snippet that you can use in any template or plugin to apply the same obfuscation to an email as using the shortcode:
if(function_exists(‘eos_obfuscate’)) 
{ 
 echo eos_obfuscate(array(’email’ => $email, ‘link_title’ => ‘Email Bob!’)); 
} 
else 
{ 
 echo $email; 
}
If the plugin is not enabled, the email address will just pass through and output in cleartext.
