<p>Mail Doctor replaces WordPress’ default <code>wp_mail</code> stack with authenticated SMTP or provider APIs plus the operational tooling fast-moving stores need. It is written for merchants, agencies, and reliability teams that want hard proof their receipts, fulfillment notices, and alerts land every time.</p>
<h4>Feature Highlights</h4>
<ul>
<li><strong>Deliverability with guardrails</strong> – Route WooCommerce or all site email through your preferred SMTP/API provider, lock the From identity, and fail over gracefully when third-party endpoints go dark.</li>
<li><strong>One-click diagnostics</strong> – Send live tests with TLS/auth badges, latency metrics, DNS posture (SPF/DKIM/DMARC), and actionable warnings the moment something drifts.</li>
<li><strong>Reliable retries & queue control</strong> – Automatic exponential backoff, manual retry orchestration, Action Scheduler integration, and a “run queue now” control for urgent flushes.</li>
<li><strong>Deep visibility</strong> – Searchable logs with <code>.eml</code> downloads, header/body inspection, filterable status views, and CSV exports for audits.</li>
<li><strong>Email template workflow</strong> – Version history, diff previews, modal device switcher, and send-test flows for the WooCommerce template editor.</li>
<li><strong>Automation surface</strong> – REST API endpoints and WP-CLI commands mirror UI actions so you can script smoke tests, tail logs, or trigger retries in CI/CD pipelines.</li>
<li><strong>Privacy-first options</strong> – Hash or redact recipients, tune retention windows, and honour GDPR requests through the bundled exporters/erasers.</li>
<li><strong>Operational alerts</strong> – Instant Slack/email failure alerts plus weekly digests summarising throughput, latency, retries, and queue health.</li>
</ul>
<h3>External Services</h3>
<p>This plugin acts as a connector between your WordPress site and third-party email providers. When you configure an external service (SMTP or API), this plugin transmits email data to that provider for delivery.</p>
<p><strong>Data Sent:</strong><br />
*   Sender and Recipient names and email addresses.<br />
*   Email subject, body content (HTML/Text), and headers.<br />
*   Timestamps and potentially the originating IP address.</p>
<p><strong>When Payload is Sent:</strong><br />
*   Immediately whenever an email is triggered by WordPress, WooCommerce, or another plugin, <em>if</em> that specific provider is currently set as your active transport.</p>
<p><strong>Purpose:</strong><br />
*   To reliably deliver transactional emails to user inboxes using the provider’s infrastructure.</p>

<h4>Quick Start</h4>
<ol>
<li>Review the documentation link in the Documentation section for the full tour and terminology.</li>
<li>Configure SMTP/API credentials on <strong>WooCommerce <span aria-hidden="true" class="wp-exclude-emoji">→</span> Mail Doctor <span aria-hidden="true" class="wp-exclude-emoji">→</span> Settings</strong>.</li>
<li>Send a test email from the <strong>Status</strong> tab and verify DNS/auth posture.</li>
<li>Visit <strong>Logs</strong> to confirm entries are stored and retries are scheduled as expected.</li>
<li>Enable alerts and weekly digests so the team knows when to act.</li>
</ol>
<h4>Documentation</h4>
<p>Documentation: https://wpdoctorpro.com/docs/mail-doctor/welcome-to-mail-doctor – guides, setup, troubleshooting, and support.</p>
<h4>Privacy controls</h4>
<p>Mail Doctor ships with built-in privacy tooling under <strong>Settings <span aria-hidden="true" class="wp-exclude-emoji">→</span> Logging & Privacy</strong>:</p>
<ul>
<li><strong>Mask recipient emails:</strong> Hashes addresses before storing them in logs.</li>
<li><strong>Redact headers and bodies:</strong> Keeps metadata only so sensitive content is not persisted.</li>
<li><strong>Retention windows:</strong> Separate sliders for sent, failed, and payload data; shorten for stricter compliance.</li>
<li><strong>GDPR exporter/eraser:</strong> WordPress privacy tools are wired to export or anonymise recipient rows on request.</li>
<li><strong>Role-based access:</strong> Admin UI and AJAX endpoints are gated by <code>manage_woocommerce</code>/<code>manage_options</code>.</li>
</ul>
<h4>Troubleshooting</h4>
<ul>
<li>Red notices on the Status tab usually indicate DNS or authentication drift—re-run the onboarding checks and confirm credentials with your provider.</li>
<li>If the queue stalls, visit <strong>Settings <span aria-hidden="true" class="wp-exclude-emoji">→</span> Retry & Queue</strong> and use <strong>Run queue now</strong>; check your cron runner or Action Scheduler if jobs remain pending.</li>
<li>Use the <code>.eml</code> download from each log entry when escalating to your SMTP provider—they can analyse the exact payload and SMTP transcript.</li>
<li>For privacy incidents, toggle Privacy Mode and shorten retention while you investigate; the GDPR exporter/eraser handles customer requests.</li>
</ul>
<h3>Support & Packaging</h3>
<ul>
<li>Requirements: WordPress 6.0+, WooCommerce (latest), PHP 8.1–8.3 with cURL/JSON; OpenSSL recommended for encrypted secret storage.</li>
<li>Included in download: <code>mail-doctor/</code> plugin folder, <code>Documentation/</code> offline HTML docs, <code>readme.txt</code>, <code>changelog.txt</code>, and <code>LICENSE</code>.</li>

<p>🚨 Are your WordPress emails going to spam?</p>
<p>Without proper email authentication, services like Gmail, Outlook, and Yahoo may block or mark your emails as spam. This results in lost notifications, password resets, and order emails.</p>
<p>SignEmail SMTP helps you send reliable WordPress emails using professional SMTP servers, with optional DKIM authentication support.</p>
