SES for WordPress
<h3></h3>
Introduction
This plugin provides support for AWS’s Simple Email Service for your WP site. It supports arbitrary custom headers and handles image embedding for you. It sends HTML messages with an automatically-generated plain-text counterpart.
By default, it overrides the native wp_mail function, so all you need to do is configure your AWS Keys and sender in Settings > SES4WP Options.
Components
<ol>
<li>PEAR Mime_mail to create the message</li>
<li>Jevon Wright’s <a href="http://journals.jevon.org/users/jevon-phd/entry/19818" rel="nofollow ugc">html2text</a> for the plain-text part</li>
<li>AWS SDK v1.5</li>
</ol>
Embedding images
Before your call to wp_mail(), call <code>ses4wp_embed_image</code> with an image handle and the path to your image. It will return a content_id for you to use in your src attribute.
Paths should be given relative to your webserver root. So for instance, to embed <code>wp-content/themes/twentyeleven/images/wordpress.png</code>, you would omit the slash at the beginning.
eg
<pre><code>$content_id = ses4wp_embed_image( 'my_image', 'wp-content/path/to/image.jpg' );
$mail_body = "This is an image. <img src='cid:$content_id' />";
wp_mail( 'bob@example.com', 'My Subject', $mail_body );
</code></pre>
The image will be attached to the email and delivered inline.

SES for WordPress

Use Amazon SES to send emails with embedded images and arbitrary headers.

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.
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.
Particularly good with Amazon SES where there are tight restrictions for sender lists and in sandbox mode only validated addresses may receive messages.
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.
Features:
<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.
