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.
<h4>Feature Highlights</h4>
<ul>
<li>Deliverability with guardrails – 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>One-click diagnostics – Send live tests with TLS/auth badges, latency metrics, DNS posture (SPF/DKIM/DMARC), and actionable warnings the moment something drifts.</li>
<li>Reliable retries & queue control – Automatic exponential backoff, manual retry orchestration, Action Scheduler integration, and a “run queue now” control for urgent flushes.</li>
<li>Deep visibility – Searchable logs with <code>.eml</code> downloads, header/body inspection, filterable status views, and CSV exports for audits.</li>
<li>Email template workflow – Version history, diff previews, modal device switcher, and send-test flows for the WooCommerce template editor.</li>
<li>Automation surface – 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>Privacy-first options – Hash or redact recipients, tune retention windows, and honour GDPR requests through the bundled exporters/erasers.</li>
<li>Operational alerts – Instant Slack/email failure alerts plus weekly digests summarising throughput, latency, retries, and queue health.</li>
</ul>
<h3>External Services</h3>
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.
Data Sent: 
* Sender and Recipient names and email addresses. 
* Email subject, body content (HTML/Text), and headers. 
* Timestamps and potentially the originating IP address.
When Payload is Sent: 
* Immediately whenever an email is triggered by WordPress, WooCommerce, or another plugin, if that specific provider is currently set as your active transport.
Purpose: 
* To reliably deliver transactional emails to user inboxes using the provider’s infrastructure.

</ul>
<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 WooCommerce → Mail Doctor → Settings.</li>
<li>Send a test email from the Status tab and verify DNS/auth posture.</li>
<li>Visit Logs 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>
Documentation: https://wpdoctorpro.com/docs/mail-doctor/welcome-to-mail-doctor – guides, setup, troubleshooting, and support.
<h4>Privacy controls</h4>
Mail Doctor ships with built-in privacy tooling under Settings → Logging & Privacy:
<ul>
<li>Mask recipient emails: Hashes addresses before storing them in logs.</li>
<li>Redact headers and bodies: Keeps metadata only so sensitive content is not persisted.</li>
<li>Retention windows: Separate sliders for sent, failed, and payload data; shorten for stricter compliance.</li>
<li>GDPR exporter/eraser: WordPress privacy tools are wired to export or anonymise recipient rows on request.</li>
<li>Role-based access: 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 Settings → Retry & Queue and use Run queue now; 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>
<li>Support/Contact: See the Documentation section for guides and support links. When requesting help, include your WP/Woo versions, provider, and a recent log ID from Mail Doctor → Logs.</li>
</ul>

Provider: Google LLC
