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>

Mail Doctor

Deliver WooCommerce emails with confidence using authenticated SMTP transports, visual diagnostics, and automated retries.

codecasastudios

CodeCasaStudiosLtd

Casa Mail is an end-to-end email platform for WordPress sites. It intercepts every <code>wp_mail()</code> call and delivers it through the Casa Mail gateway operated by CodeCasa Studios on the OnlineStoreNotifications infrastructure (api.onlinestorenotifications.com). On top of reliable transactional delivery it adds a full marketing platform, branded webmail mailboxes, and one-click sender-domain authentication, all driven from the WordPress admin.
If your site doesn’t send mail reliably today, Casa Mail is the simplest way to start. If you’re already paying for an SMTP plugin plus a separate marketing tool plus a separate webmail provider, Casa Mail consolidates the three so you can run customer email, broadcasts, and inbox replies from one place.
<h4>What you get</h4>
Transactional email (every plan, including Free)
<ul>
<li>Every <code>wp_mail()</code> is routed through the Casa Mail gateway with DKIM, SPF, and aligned Return-Path on <code>onlinestorenotifications.com</code> (or your own domain after one-click authentication).</li>
<li>Durable retry outbox: if the gateway is briefly unreachable, the payload is persisted and retried automatically with 30s, 2m, 10m backoff. <code>wp_mail()</code> never blocks, never loses a message, never returns false to the caller.</li>
<li>Per-tenant inbox at <code><your-site>@onlinestorenotifications.com</code>. Replies to your customer emails come back to that inbox; on the Free tier they auto-forward to your contact address. On webmail-enabled plans you can also receive replies on your own domain (e.g. <code><your-inbox>@yourdomain.com</code>).</li>
<li>Paginated send log on the Logs page with up to 30 days of history retained (hard-capped at 2,000 rows per WordPress install). The Dashboard surfaces the most recent activity at a glance.</li>
<li>Optional default-From override so every site email uses one consistent sender.</li>
</ul>
Sender domain authentication (every plan)
<ul>
<li>Add your own domain in the admin and the plugin prints three DNS records (DKIM, SPF, Return-Path).</li>
<li>One-click “Check my domain” verifier. Once verified, customer emails go from <code><your-inbox>@yourdomain.com</code> so Gmail and Outlook show your brand in the From, not “via onlinestorenotifications.com”.</li>
<li>Inline plain-English helpers for Cloudflare, GoDaddy, Namecheap, and Google Domains. Cloudflare grey-cloud guidance for replies is built in.</li>
<li>Free plan can opt out of domain authentication entirely and send from the shared <code><your-inbox>@onlinestorenotifications.com</code> address with DKIM/SPF/Return-Path already configured on the gateway.</li>
</ul>
Marketing Studio (Growth and higher)
<ul>
<li>Contacts: add manually, import from CSV, or one-click sync your WooCommerce customer base.</li>
<li>Segments: saved queries (all contacts, contacts with a specific tag) with a sample-preview before you send.</li>
<li>Campaigns: schedule a broadcast to a segment, watch send progress on a per-campaign report (sent, opens, unique-by-contact open + click rate).</li>
<li>Composer: full block-based visual editor with heading / paragraph / image / button / divider / spacer / two-columns / raw-HTML blocks, per-block and global style settings, Visual / Source HTML / Wrapper / Preview tabs, desktop + mobile preview, 50-step undo/redo, emoji picker, drag-and-drop images into the WordPress media library, per-tenant saved templates.</li>
<li>Personalization tokens: <code>[FIRST_NAME]</code>, <code>[LAST_NAME]</code>, <code>[FULL_NAME]</code>, <code>[EMAIL]</code>, <code>[UNSUBSCRIBE_URL]</code>.</li>
<li>Suppressions: paginated list with bounce / complaint / unsubscribe filters, manual add, CSV export. Bounces and FBL complaints are fanned out from the gateway automatically so you never have to clean a list by hand.</li>
</ul>
Casa Webmail mailboxes (Growth and higher)
<ul>
<li>Self-hosted branded webmail at <code>webmail.onlinestorenotifications.com</code>. Sign in with <code><your-inbox>@onlinestorenotifications.com</code> from any browser and read and reply to customer replies from a clean inbox.</li>
<li>Use your own domain too: point your domain’s MX records at <code>mx.sendemailtoday.io</code> and replies to <code><your-inbox>@yourdomain.com</code> land in the same webmail UI, signed by the platform DKIM.</li>
<li>Real Maildir storage on the Casa Mail backbone. No third-party Gmail forwarding.</li>
</ul>
Billing and plan management
<ul>
<li>One-click upgrade from Free to Starter, Growth, Business, or Agency. Stripe Checkout opens in a new tab; the plugin never sees your card details.</li>
<li>Paid plans are also available straight from the onboarding wizard, so you can start on the right tier from day one.</li>
<li>In-WordPress quota-usage display with an “approaching cap” banner so a busy month doesn’t surprise you mid-send.</li>
<li>Stripe-hosted billing portal for change-card, change-plan, view-invoices, cancel.</li>
</ul>
Built-in trust and safety
<ul>
<li>Sender-domain enforcement so a misconfigured WordPress install can never send under someone else’s domain by accident.</li>
<li>Gateway-side content review on marketing broadcasts: a separate moderation layer scans campaigns and pauses anything that looks like phishing, brand impersonation, or credential harvesting before it reaches your recipients. The gateway operator reviews flagged content and contacts you with the reason. This protects your sender reputation.</li>
</ul>
<h4>Pricing</h4>
<ul>
<li>Free: 10,000 transactional emails per month, full quota from day one (no daily ramp), 500/day soft cap. Custom-domain authentication included. No credit card required.</li>
<li>Starter (GBP 9/month): 25,000 emails per month, 2,500/day cap. Custom-domain authentication.</li>
<li>Growth (GBP 29/month): 100,000 emails per month, Marketing Studio (contacts, segments, campaigns, visual editor, suppressions), 1 branded Casa Webmail mailbox.</li>
<li>Business (GBP 79/month): 500,000 emails per month, Marketing Studio, 5 mailboxes.</li>
<li>Agency (GBP 199/month): 2,000,000 emails per month, Marketing Studio, 25 mailboxes.</li>
</ul>
Upgrades and downgrades are entirely self-serve from Settings -> Casa Mail -> Billing. Cancellation is one click from the Stripe-hosted portal; you keep service through the end of your billing cycle.
<h4>How it works (transactional path)</h4>
<ul>
<li><code>pre_wp_mail</code> is hooked at priority 1. Each call is converted to a JSON payload and POSTed to the gateway.</li>
<li>If the gateway accepts on the first POST, <code>wp_mail()</code> returns true and the message is durably enqueued upstream.</li>
<li>If the gateway is unreachable on the first POST, the payload is written to a durable outbox table (<code><prefix>casamail_outbox</code>) and a cron tick retries with 30s, 2m, 10m backoff.</li>
<li>A separate transmit log table (<code><prefix>casamail_sends</code>) records every attempt for visibility on the plugin dashboard. Rows older than 30 days are pruned automatically.</li>
</ul>
<h4>Onboarding</h4>
After activation, an in-WordPress wizard collects:
<ol>
<li>Site name, site URL, contact email address.</li>
<li>A 6-digit code emailed by the gateway to confirm the address.</li>
<li>The handle to use for your inbox (defaults to a friendly version of your site URL, e.g. <code>acmestore</code>).</li>
<li>Plan selection. Five tiers shown side-by-side (Free, Starter, Growth, Business, Agency); pick Free to get started immediately, or pick a paid tier to launch Stripe Checkout in a new tab. Either way your tenant is already provisioned so you can keep onboarding while you complete payment.</li>
<li>Where customer emails should come from: the shared Casa Mail address, or your own authenticated domain (with one-click DNS verification).</li>
</ol>
The whole onboarding is one screen with five short steps. No SMTP keys to copy, no DNS console to leave WordPress for.
<h4>Trademark note</h4>
This plugin is not affiliated with or endorsed by WooCommerce, Automattic, or any third party. The WooCommerce name appears only as a compatibility note (when WooCommerce is detected, the plugin’s admin menu attaches under it for convenience; otherwise it lands under Settings).
<h3>External services</h3>
This plugin transmits data to a third-party SMTP gateway. WordPress.org policy requires this be disclosed.
<h4>Endpoints contacted</h4>
The plugin makes HTTPS requests to:
<ul>
<li><code>https://api.onlinestorenotifications.com/v1/onboard/request</code> – during onboarding, to send your verification email.</li>
<li><code>https://api.onlinestorenotifications.com/v1/onboard/verify</code> – during onboarding, to confirm the code and provision an account.</li>
<li><code>https://api.onlinestorenotifications.com/v1/send</code> – for every <code>wp_mail()</code> call once the plugin is onboarded.</li>
<li><code>https://api.onlinestorenotifications.com/v1/email/domain</code> (GET / add / verify) – when the site administrator interacts with the Sender Domain page.</li>
<li><code>https://api.onlinestorenotifications.com/v1/billing/*</code> – checkout, billing portal, plan status. Only invoked when the site administrator interacts with the Billing page or picks a paid tier during onboarding.</li>
</ul>
The gateway is operated by CodeCasa Studios under the Casa Mail brand and runs on the OnlineStoreNotifications infrastructure. Casa Mail and OnlineStoreNotifications are sister brands of the same company; the API hostname reflects the shared backbone rather than a third-party dependency.
<h4>Data sent</h4>
During onboarding (one-time, before any send): site administrator email address, site name, site URL.
For each <code>wp_mail()</code> call once onboarded: sender email address, sender name, recipient email address(es), subject, message body, message headers (after stripping <code>From</code>/<code>To</code>/<code>Subject</code>/<code>Date</code>/<code>Message-ID</code>/<code>MIME-Version</code>/<code>Content-Type</code>/<code>Content-Transfer-Encoding</code>).
<h4>Terms and privacy</h4>
<ul>
<li>Terms of service: https://sendemailtoday.io/terms.html</li>
<li>Privacy policy: https://sendemailtoday.io/privacy.html</li>
</ul>
<h3>Privacy</h3>
When activated, this plugin transmits email content (recipient, sender, subject, body, headers) to a third-party SMTP gateway for delivery. This is the plugin’s only purpose. The data lifecycle is described above under “External services” and on the linked privacy policy.
The plugin also writes a <code>wp_add_privacy_policy_content()</code> block describing what is transmitted; this lets site administrators include the disclosure in the WordPress-managed privacy policy page (Settings -> Privacy).
Account deletion: a “Request account deletion” button on the plugin’s Settings page emails the gateway operator. Upon confirmation, the tenant record, API key(s), domain-authentication records, and recent sending history are removed from the gateway side. The plugin uninstall additionally removes the plugin’s WordPress-side options + tables.

Casa Mail

A complete email platform for WordPress: transactional SMTP, marketing campaigns, branded mailboxes, and DKIM-aligned sending from your own domain.
