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.

<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>

Excellent dashboard with lot of informations. I used it to fix the deliverability configuration of my website. After that, I didn't receive any complaint from my users about my emails marked as spam in their inbox.



Really effective!


Great plugin


The plugin is very well made and the code is organized and clean which is truly a plus, an added value in the sea of plugins that often bring down the performance of websites due to the poor quality of the written code.

I highly recommend trying it to all users who have problems with mail delivery from their WordPress site and who have to struggle with this annoying problem every day.

It makes checking email deliverability a breeze


The plugin offers a straightforward and user-friendly experience. Following the simple instructions in the settings page, I successfully added the TXT record to my DNS and my emails were successfully signed. I particularly appreciate the delivery chart and the dashboard, which provide valuable insights on my email deliveries and how to enhance it. These features empower me to ensure a safer and more reliable communication to my customers.


A standout plugin


Unfortunate I do not recieve any email for verifications my account. Tried on different installations and different emails.
