<h4>Why use SMTP?</h4>
<p>This plugin will prevent your emails from going into the junk/spam folder of the recipients.<br />
Email sent by WordPress use PHP mail() function, and often the email go in the spam folder or get completely rejected by popular email providers.<br />
SMTP (Simple Mail Transfer Protocol) is the industry standard for sending emails.<br />
This plugin helps you use proper authentication which increases email deliverability.</p>
<h4>Why use this SMTP plugin?</h4>
<p>There are many WP plugins for SMTP, but this one aim to be simple by using lightweight code (single file less than 4KB), without storing anything on database, but doing configuration only via wp-config.php. Also there is not complete override of wp_mail() function like other plugins, but it’s used only hook for add additional functionality; this allow easy upgrade to future version of WP.</p>
