Creates an email link from the shortcode [emailme] that spam bots don’t find. 
By default it uses your wp admin email but you can specify as parameters either: 
 – ‘name’ (for the first portion of the email before the @ symbo) 
 – ‘addr’ for the full email 
 – ‘display’ for what the link should actually display in between the <a> tags.</a>
If your wp-admin panel email (check your General Setting panel) 
is: info@freedomonlineservices.net then 
Examples: [emailme] => info@freedomonlineservices.net 
 [emailme name=’dave’] => dave@freedomonlineservices.net 
 [emailme addr=’someoneelse@somewhereelse.fake’] => someoneelse@somewhereelse.fake 
 [emailme display=”info at freedomonlineservices dot net”] => info at freedomonlineservices dot net (but linked to the actual email!) 
Note you can also set the ‘display’ option to an image tag if you use single quotes.

This plugin provides an unobtrusive yet efficient protection against email harvesters / spambots. Here is a <a href="https://pixeline.be/blog/email-protector-demo-4258.html" rel="nofollow ugc">demo</a>.
Post/page authors may write email addresses in their article in the usual format (“john@doe.com”) without exposing them to spam email harvesters. The plugin takes care of the obfuscation, implementing a graceful degradation technique focusing on usability so as to protect your email addresses from harvesters while keeping them usable to your human visitors.
The plugin replaces any email address found in posts, pages, comments and excerpts, and replace them by a bit of html markup that should deceive most email harvesters: <code>john(replace the parenthesis by @)doe.com</code>. 
If javascript is available, it will display a clickable link and display the original email to the human user. Maximum usability, maximum protection.
Please <a href="https://wordpress.org/extend/plugins/pixelines-email-protector/" rel="ugc">rate the plugin</a> if you like it.
<h3>Usage</h3>
Write your email addresses inside your posts and pages as usual. When the plugin is activated, it will replace them by a human-readable html string that explains how to deduce the email address, and if javascript is available (99.9% of the time), the original email address will be displayed as a clickable mailto: link. For example: 
 Hello john@doe.com. How are you today? 
will become 
 John( replace these parenthesis by @ )doe.com.
Additionally, you can specify what the mailto: link should look like by sticking a parenthesis inside of which you put the visible link text, like this:
<pre><code>Hello john@doe.com(John Doe). How are you today?
</code></pre>
will become 
 John( replace these parenthesis by @ )doe.com.
<h4>inside a theme</h4>
If you need to protect emails inside your Theme’s files (like the footer.php for example), you can use the function safe_email() like this:
<pre><code> echo safe_email('you@domain.com'); <h3>Contribute</h3>
</code></pre>
