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>

WP Mail Logging is the most popular plugin for logging emails sent from your WordPress site. Simply activate it and it will work immediately, no extra configuration is needed.
<h3>Are your WordPress emails not being sent or delivered?</h3>
Use this plugin to log all outgoing emails from your WordPress site. If there are any errors when sending the email from your site, our email logs will catch that error and display it to you.
This will allow you to debug and fix your email sending issue.
<h3>Did a client not receive your email?</h3>
Our email logs allow you to resend any email that was sent from your site. No more lost emails!
<h3>Do you just want to keep a record of all emails sent from your site?</h3>
By default, WordPress and your web host do not log, store or keep track of emails sent from your website.
This plugin will allow you to do just that. Our email logs will store every email that is sent from your WordPress site.
You can search and view a particular email log, inspect its content or attachments, and even resend that email.
<h3>What email information is logged?</h3>
All emails sent from your WordPress site are logged. And here is the information that is stored:
<ul>
<li>Email Subject</li>
<li>Email Content (HTML or text)</li>
<li>Email Attachments</li>
<li>Email Headers (to, from, reply-to, cc, bcc, …)</li>
<li>Error Message (in case there was an error while attempting to send the email)</li>
<li>IP Address of originating server (can be enabled in the settings)</li>
<li>Date and Time of the email</li>
<li>Receiver (the TO email address)</li>
</ul>
<h3>Why are my logged emails still not delivered to the inbox?</h3>
There are a lot of steps that emails have to make in order to be delivered to the recipient’s inbox.
When your WordPress site sends an email, there’s no guarantee it will be delivered.
This is what the email’s journey looks like:
<ol>
<li>WordPress creates an email</li>
<li>WordPress passes the email to your website host and that email gets logged by our plugin</li>
<li>The host server takes the email and sends it (SMTP or Mail Transfer Agent)</li>
<li>Recipient server receives or blocks the email</li>
<li>If the email is accepted, the spam filter decides if it goes to the inbox or the spam folder</li>
<li>Recipients see the email and might open it.</li>
</ol>
This plugin does not track delivery after step 2.
If you have deliverability issues, we suggest installing the <a href="https://wordpress.org/plugins/wp-mail-smtp/" rel="ugc">WP Mail SMTP</a> plugin.
WP Mail SMTP fixes WordPress email deliverability problems, you can choose between 12 email providers (Gmail, Outlook, SendLayer, Mailgun, …) to resolve your email sending issue and it’s super easy to set up. WP Mail SMTP is trusted by more than 3 million websites.
<h3>Credits</h3>
The plugin was created and launched in 2014 by <a href="https://no3x.de/" rel="nofollow ugc">Christian Zöller</a>.

WP Mail Logging

Great plugin


It's great te be able to see all outgoing emails with the formatting. No wonder why this plug-in is recommended by the Woocommerce support staff!


Super useful!


Very easy to moving from local server to live site


moving from local server to live


Love this plugin!  Acts as a great debugging tool when outgoing SMTP is not working (seen often on VPS hosted instances without something like WP SMTP configured).  


Great debugging tool!


Nothing really more to write. I've been using the plugin for quite some time and haven't experienced any unexpected behavior.


Works seamlessly right after activation

Works well


Very useful seeing what should have gone out and figure out if there's something wrong with my mail server.


Helps keep my sanity


Sending email from WP can be problematic when the provider has a poor mailing service. This plugin is perfect to monitor the email activity, find possible problems, resend emails.



I'm using it simple and very complex sites. It's particularly useful to track emails sent by plugins (ecommerce, form managers and so on): most of the time, when there are problems, they can be solved looking at the log.



IMHO every site should have it.


A must have


Love this plugin. Save me from huge lose. 


Little but huge impact. Very helpfull

Log, view, and resend all emails sent from your WordPress site. Great for resolving email sending issues or keeping a copy for auditing.
