<p>API Mailer for AWS SES replaces <code>wp_mail()</code> with a direct Amazon SES API integration (SendRawEmail). There is no SMTP layer or PHPMailer handoff in the critical path, reducing overhead and improving reliability.</p>
<p>The plugin focuses on correctness, performance, and operational clarity:<br />
– Direct AWS SigV4 signed requests to SES<br />
– Minimal overhead in the <code>wp_mail()</code> hook<br />
– Optional background queue with Action Scheduler or wp_cron fallback<br />
– Optional logging via WooCommerce logger or PHP error_log<br />
– Clean, PSR-4 structured codebase</p>
<h3>Key Features</h3>
<ol>
<li>Direct SES API (SendRawEmail) integration — no SMTP required.</li>
<li>Background sending queue with Action Scheduler or wp_cron fallback.</li>
<li>Tiny-args queueing with job IDs to keep cron payloads small and private.</li>
<li>Configurable rate limiting per second to stay under SES send rate.</li>
<li>From/Reply-To handling with optional forced From and custom X-* headers.</li>
<li>Test tab to send a test email and a Status tab to fetch SES GetSendQuota.</li>
<li>Logging via WooCommerce logger or PHP error_log, disabled by default.</li>
<li>Credentials from wp-config (constants) or saved settings.</li>
<li>Lightweight, minimal I/O, no Composer dependency.</li>
<li>Uninstall cleanup toggle to remove settings and queued jobs on deletion.</li>
</ol>
<h3>Why It’s High Performance</h3>
<ul>
<li>Avoids SMTP for the send path; uses PHPMailer only for MIME construction, then sends via SES API directly.</li>
<li>Background queue returns control to the request immediately when enabled.</li>
<li>Job payloads are stored server-side and referenced by a small <code>job_id</code> to avoid large serialized cron arguments.</li>
<li>Logging is optional and disabled by default to keep I/O low.</li>
</ul>
<h3>Configuration</h3>
<h3>Credentials in wp-config (recommended)</h3>
<p>Define the following constants above “That’s all, stop editing!” in <code>wp-config.php</code>, then enable “Read AWS credentials from wp-config” in the plugin settings.</p>
<pre><code>define('SES_MAILER_ACCESS_KEY', 'YOUR_ACCESS_KEY_ID');
define('SES_MAILER_SECRET_KEY', 'YOUR_SECRET_ACCESS_KEY');
define('SES_MAILER_REGION', 'us-east-1');
</code></pre>
<p>When this mode is enabled, the Access Key, Secret, and Region fields are cleared, disabled, and ignored.</p>
<h3>Background Sending</h3>
<ul>
<li>When enabled, emails are queued and sent out of band by Action Scheduler if available, or by wp_cron as a fallback.</li>
<li>The plugin stores the full email payload in an option keyed by <code>ses_mailer_job_{uuid}</code> (autoload = no) and schedules a tiny cron/action with only <code>job_id</code>.</li>
<li>Retries: up to 3 total attempts with exponential backoff (60s, then 120s).</li>
<li>For consistent cron execution on low-traffic sites, configure a real system cron to call <code>wp-cron.php</code> regularly.</li>
</ul>
<h3>Rate Limiting</h3>
<ul>
<li>A per-email pause is applied based on the configured send rate to avoid exceeding SES limits.</li>
</ul>
<h3>Logging</h3>
<ul>
<li>When enabled, log entries route to WooCommerce Status <span aria-hidden="true" class="wp-exclude-emoji">→</span> Logs (source: api-mailer-for-aws-ses) if WooCommerce is active, or to the PHP error log otherwise.</li>
<li>Logging is disabled by default. Uncheck “Disable logging” in settings to enable.</li>
</ul>
<h3>External Services</h3>
<ul>
<li>This plugin connects to Amazon Simple Email Service (AWS SES) at <code>https://email.{region}.amazonaws.com</code> to send email and to fetch sending quotas.</li>
<li>Data sent on each email: recipients, subject, message body, headers, attachments, and your AWS access key ID (signed via AWS SigV4); required to deliver the email.</li>
<li>Data sent when checking quotas: your AWS access key ID and a signed request; no recipient data is sent.</li>
<li>Service terms: https://aws.amazon.com/service-terms/ — Privacy: https://aws.amazon.com/privacy/</li>
</ul>
