<p>The plugin adds a mail queue system that can intercept all the emails sent through the <code>wp_mail</code> function, and depending on the predefined rules (number of recipients), sent the email into the queue, with each recipient getting their email. On top of that, the plugin can process all plain text emails and wrap them in the HTML, and send them as HTML, with options to customize the template and various other aspects.</p>
<h4>How the plugin works</h4>
<p>The central part of the plugin, called ‘Mailer,’ controls the process.</p>
<ul>
<li>Intercept every <code>wp_mail</code> call</li>
<li>If needed, wrap email in HTML</li>
<li>Determine the number of recipients</li>
<li>If eligible, add each recipient email into the queue</li>
</ul>
<p>Process of turning plain text into HTML emails, support all emails sent through wp_mail, even if they don’t end in the queue. This can turn all WordPress system emails (registration, password reset…) into HTML emails and you can choose between predefined HTML templates, or register own templates via filter.</p>
<p>Queue works through the CRON, as a background job, and you can configure how many emails to send in a batch, with the timeout setting to prevent PHP timeout breaking the sending process.</p>
<h4>Email Sending</h4>
<p>Emails are sent using PHPMailer built into WordPress. But, the plugin has additional options to control the queue sending process and the wp_mail sending process.</p>
<ul>
<li>Email sending engine based on PHPMailer class</li>
<li>PHPMailer options to use SMTP for sending emails</li>
<li>Customize email From for all emails passed through <code>wp_mail</code></li>
<li>Customize email From, Reply, and Sender for all emails sent through the queue</li>
</ul>
<h4>Email Logging</h4>
<p>The plugin includes an advanced email log.</p>
<ul>
<li>Custom database tables to store logs, made for performance</li>
<li>Store all relevant data for each email, including a list of attachments</li>
<li>Email log panel with filters for logged emails</li>
<li>Preview popup displaying all logged email details</li>
<li>Preview popup shows the full HTML email part preview</li>
<li>Retry sending any failed emails through the queue</li>
</ul>
<h4>Security related features</h4>
<p>The plugin will attempt to strip malicious content from intercepted email, and sanitize the email plain text before generating HTML version, with the option to control the scope of the HTML tags to allow. HTML from subject will be striped. Emails stored in the log will be additionally sanitized, and on display, email content will be again escaped or run through KSES to avoid issues.</p>
<h4>Other plugin features</h4>
<ul>
<li>Options to pause wp_mail and queue operations</li>
<li>Dashboard: an overview of the queue (including the last run) statistics</li>
