All webmasters experience the problem of their emails landing in their users spam folders, including our own! 
So we decided to develop a simple solution to fix this wide-spread annoyance. 
After a long development period, we have produced an effective method of sending emails which complies 
in full with all guidelines and security requirements of email providers such as Google, Yahoo & MSN.
<h3>Markdown</h3>
<ul>
<li>Your emails will no longer be marked as SPAM.</li>
<li>If your emails do not even arrive to Yahoo! or MSN with Xmail they will.</li>
<li>This is the way Google, Yahoo! and MSN best like emails to come to them.</li>
</ul>

Xmail – The Right Way

Replaces wp_mail and sends email the right way so it does not get flagged as SPAM.
