<li>Does not store credentials in the database</li>
<li>Convention over configuration</li>
<li>Removed any functionality which can be done via AWS Console</li>
<li>Open Source and <a href="https://github.com/bashaus/wp-mail-ses/" rel="nofollow ugc">version controlled via GitHub</a></li>
</ul>

WP Mail SES

Uses Amazon Web Services (AWS) Simple Email Service (SES) to send emails in WordPress.

<p>Use SMTP with authentication to deliver messages from WordPress. Intercepts wp_mail function to allow you to define the server, port, connection security and credentials.</p>
<p>Designed initially as a replacement for the wp_mail function, this plugin uses the core WordPress mail functions and extends only the settings needed to allow connection to third-party mailing systems that require authentication and have sender and recipient restrictions.</p>
<p>Particularly good with Amazon SES where there are tight restrictions for sender lists and in sandbox mode only validated addresses may receive messages.</p>
<p>You can also simply use this to force sender and receivers for any messages from WordPress as well as set the default name in messages originating from your site.</p>
<p>Features:</p>
<ul>
<li>Flexible configuration works with basically any mail service and protocol</li>
<li>Test function will allow you to diagnose specific errors in the email transmission</li>
<li>Able to handle Amazon Sandbox restrictions by overriding the recipient and sending only to an authorized address</li>
<li>Debug mode to capture transmission logs from phpmailer</li>
</ul>


MBC SMTP Flex

Extends wp_mail function to allow you to define the server, port, connection security and credentials.
