WP Offload SES Lite


WP SES is now WP Offload SES Lite. WP Offload SES Lite sends all outgoing WordPress emails through Amazon Simple Email Service (SES) instead of the local wp_mail() function.

This ensures high email deliverability, email traffic statistics and a powerful managed infrastructure.

With WP Offload SES Lite, you can:

  • Effortlessly configure your site to send all email via Amazon SES with our step-by-step setup wizard
  • Configure the default email address and name that WordPress uses for notifications
  • Send verification requests for new domains and email addresses
  • Send a test email to make sure everything is working before enabling site-wide email sending
  • View a list of all emails sent from your site
  • View statistics on your Amazon SES send rate
  • Set up a custom “Reply To” and “Return Path” address
  • Configure multisite subsites to use different email settings, or enforce the same settings for your whole network
  • Integrate with your favorite form and newsletter plugins, including Ninja Forms, Contact Form 7, Gravity Forms, Email Subscribers & Newsletters, and more

Where can I get support for the plugin?

If you upgrade to WP Offload SES, we will gladly provide you with email support. We take pride in delivering exceptional customer support. We do not provide email support for the free version.

What are the minimum requirements?
  • Latest version of WordPress or the one previous
  • PHP 5.5+ compiled with the cURL extension
  • MySQL 5.5+
  • Apache 2+ or Nginx 1.4+
  • Amazon Web Services account
Does this plugin auto-retry email delivery failures?

While you can see a list of all emails sent from your site with this plugin, WP Offload SES Lite does not auto-retry failures (nor does Amazon SES). If you’d like a plugin that will auto-retry for you, upgrade to WP Offload SES.

Can you help me about… (an Amazon concern)

Please direct your specific Amazon questions to Amazon support.

How does this work on WordPress Multisite?

You can configure the entire network to use the same settings by configuring the plugin via the Network Admin settings screen. If a subsite should have different settings, you can override some or all of the network settings by going to the WP Offload SES Lite settings page for that subsite.

You can also use the WPOSES_SETTINGS constant to define settings that will be applied to all subsites and can’t be overridden via the UI:

define( 'WPOSES_SETTINGS', serialize( array(
    // Send site emails via Amazon SES.
    'send-via-ses'          => true,
    // Enable open tracking.
    'enable-open-tracking'  => true,
    // Enable click tracking.
    'enable-click-tracking' => true,
    // Amazon SES region (e.g. 'us-east-1' - leave blank for default region).
    'region'                => 'us-east-1',
    // Changes the default email address used by WordPress
    'default-email'         => 'your-email@example.com',
    // Changes the default email name used by WordPress.
    'default-email-name'    => 'Your Name Here',
    // Sets the "Reply-To" header for all outgoing emails.
    'reply-to'              => 'your-email@example.com',
    // Sets the "Return-Path" header used by Amazon SES.
    'return-path'           => 'your-email@example.com',
    // Amount of days to keep email logs (e.g. 30, 60, 90, 180, 365, 730)
    'log-duration'          => '30',
) ) );

See our documentation on this for more information.

Do you have a hook that is fired when an email is sent?

Yes, the wposes_mail_sent hook could be used to log emails, or post email info to an API or database:

function myMailSentHook( $to, $subject, $message, $headers, $attachments ) {
    // Your code here.
add_action( 'wposes_mail_sent', 'myMailSentHook', 10, 5 );
Can I create a translation for your plugin?

Yes, please do! It’s easy.

  1. Visit translate.wordpress.org
  2. Choose your locale
  3. Click on Plugins
  4. Search for WP Offload SES Lite
  5. Click on WP Offload SES Lite
  6. Translate!
Will WP Offload SES Lite work with other plugins that send email?

Yes, WP Offload SES should be compatible with any plugin that uses the standard wp_mail() function for sending email. If you’ve found a plugin that isn’t using that function for sending mail, you may want to reach out to the plugin developer and see if that can be changed.

Why aren’t my AWS access keys working?

Please double check the credentials match up with the credentials you received when creating your IAM user, and that your IAM user has the AmazonSESFullAccess permission.



Thank you for this super convenient plugin. Highly professional Step by Step Guide for free. Awesome for outsourcing Mailing to SES.
I posted this error in the support forum and with no answer after a few days I moved on. https://wordpress.org/support/topic/error-512-signaturedoesnotmatch/#post-10579859 SES is working for AWS WorkMail and other uses. This plug-in was the only problem. WP-SES has potential. Hope they figure this out.
