A user requests a password reset that never arrives. You have no idea — everything looks fine in the admin. WordPress has no native email log. When an email doesn’t arrive, there’s no trace of what happened, why it failed, or even whether it was sent at all. **GrL’Ca MailGuard fixes that.** It hooks directly into `wp_mail()` and records every single outgoing email — recipient, subject, status, SMTP response, and full error details. Zero configuration needed to start logging. ### 🔍 Complete Email Audit Trail Every email your site sends is recorded with: * Recipient address and subject line * Delivery status (sent or failed) * Exact SMTP server response * Full error message on failure * Automatic email type detection (WooCommerce orders, password resets, new user registrations, and 20+ more) ### 🔄 One-Click Resend Found a failed email in the log? Resend it directly from the log table with a single click. No copy-pasting, no manual re-triggers. The original recipient, subject, and content are used automatically. ### 🔧 SMTP Configuration Configure your outgoing mail server with quick-select presets for the most popular providers: * Gmail / Google Workspace * Microsoft 365 / Outlook * SendGrid * Mailgun * Brevo (formerly Sendinblue) * Amazon SES * Any custom SMTP server A built-in test button sends a verification email and shows the exact server response so you know immediately whether your configuration works. ### 📊 Dashboard Widget At-a-glance delivery stats right on your WordPress dashboard — sent count, failed count, and delivery rate for the last 7 days. Plus a full activity chart with 7, 14, and 30-day ranges. ### 🏷️ Automatic Email Type Detection MailGuard automatically classifies every email so you can filter the log by type: ``` wc_new_order · `wc_completed_order` · `wc_cancelled_order` · `wc_refunded_order` · `password_reset` · `new_user` · `comment_notification` · and more. ``` Extend with the `grlca_mg_detect_email_type` filter to add your own types. ### ⚡ Zero Configuration to Start Activate the plugin. That’s it. MailGuard immediately begins logging every email. No API keys, no external accounts, no setup wizard required for the core functionality. ### 🚀 Free vs Pro Feature Free [Pro](https://grlca.com/mailguard/) Unlimited email log ✅ ✅ One-click resend ✅ ✅ SMTP configuration + presets ✅ ✅ Email type detection ✅ ✅ Dashboard widget + chart ✅ ✅ Email alerts on failure ❌ ✅ Slack notifications ❌ ✅ Webhook (Make, Zapier, n8n) ❌ ✅ Open + click tracking ❌ ✅ Daily digest emails ❌ ✅ CSV export ❌ ✅ SMTP diagnostics ❌ ✅ Multisite Network Admin ❌ ✅ Agency plan White-label branding ❌ ✅ Agency plan Price Free forever [From €49 one-time](https://grlca.com/mailguard/) 👉 [Learn more about MailGuard Pro ](https://grlca.com/mailguard/) ### 🤝 Compatible With Everything * WooCommerce (all versions) — order emails, invoices, refunds * All SMTP plugins (WP Mail SMTP, FluentSMTP, Easy WP SMTP…) * WordPress Multisite * Any plugin that uses `wp_mail()` * Custom code that calls `wp_mail()` directly ### 🛡️ Privacy MailGuard stores email metadata (recipient, subject, status, error) in your own WordPress database. No data is sent to external servers. Email body storage is opt- in and disabled by default. ### External services This plugin optionally connects to a user-configured SMTP server to send outgoing emails. No SMTP connection is made unless the user explicitly enables and configures SMTP under MailGuard SMTP Setup. When SMTP is enabled, the plugin sends email content (recipient, subject, message body) to the configured SMTP server each time WordPress sends an email via wp_mail(). The plugin includes quick-select presets for the following third-party SMTP providers: * **Gmail / Google Workspace** (smtp.gmail.com) — [Terms of Service](https://policies.google.com/terms), [Privacy Policy](https://policies.google.com/privacy) * **Microsoft 365 / Outlook** (smtp.office365.com) — [Terms of Service](https://www.microsoft.com/en-us/servicesagreement), [Privacy Policy](https://privacy.microsoft.com/en-us/privacystatement) * **SendGrid** (smtp.sendgrid.net) — [Terms of Service](https://www.twilio.com/en-us/legal/tos), [Privacy Policy](https://www.twilio.com/en-us/legal/privacy) * **Mailgun** (smtp.mailgun.org) — [Terms of Service](https://www.mailgun.com/legal/terms/), [Privacy Policy](https://www.mailgun.com/legal/privacy-policy/) * **Brevo / Sendinblue** (smtp-relay.brevo.com) — [Terms of Service](https://www.brevo.com/legal/termsofuse/), [Privacy Policy](https://www.brevo.com/legal/privacypolicy/) * **Amazon SES** (email-smtp.*.amazonaws.com) — [Terms of Service](https://aws.amazon.com/service-terms/), [Privacy Policy](https://aws.amazon.com/privacy/) Users may also enter any custom SMTP server of their choice. The plugin does not send any data to external servers unless the user explicitly configures and enables SMTP. All email log data is stored locally in the WordPress database. ## Instalación **From the WordPress plugin directory:** 1. Go to **Plugins Add New** in your WordPress admin 2.

The moment you activate the plugin it starts intercepting every `wp_mail()` call. No configuration needed. ### Do I need to set up SMTP? No. MailGuard logs all emails regardless of whether you configure SMTP. However, for reliable email delivery we strongly recommend using an SMTP service (Gmail, SendGrid, Mailgun, etc.) — WordPress’s default PHP mail is often blocked by spam filters. ### Is the email log limited? No. The free version includes a fully unlimited email log. All sent and failed emails are recorded with no entry cap. Log retention is configurable under MailGuard Settings. Upgrade to [MailGuard Pro](https://grlca.com/mailguard/) for email/Slack/webhook failure alerts, open and click tracking, CSV export, and more. ### Will it slow down my site? No. The log write happens after `wp_mail()` returns, is a single indexed INSERT into a dedicated table, and has no impact on page load times. ### Does it work with WooCommerce? Yes. All WooCommerce transactional emails are automatically detected and tagged with their type (`wc_new_order`, `wc_completed_order`, etc.) so you can filter the log by order email type. ### Does it work with page builders, form plugins, etc.? Yes. Any plugin that sends email via WordPress’s `wp_mail()` function is automatically covered — Contact Form 7, WPForms, Gravity Forms, Elementor forms, and so on. ### Can I extend the email type detection? Yes. Use the `grlca_mg_detect_email_type` filter to add custom type detection logic for your own plugins. ### Is there a Pro version? Yes. [MailGuard Pro](https://grlca.com/mailguard/) adds email/Slack/webhook failure alerts, open and click tracking, daily digest reports, SMTP diagnostics, CSV export, and a Multisite Network Admin dashboard. One-time payment, no subscription. ### Does it store email content? Not by default. Only the recipient, subject, status, and error are stored. You can optionally enable full email body storage under **MailGuard Settings**, but note this may store sensitive content. ### Where is my data stored? All data is stored in your WordPress database in the `{prefix}grlca_mailguard_log` table. Nothing is sent to external servers. ### How do I delete all plugin data? Deleting the plugin from **Plugins Installed Plugins Delete** will remove all data: the log table, all options, and any scheduled events. ## Reseñas No hay reseñas para este plugin. ## Colaboradores y desarrolladores «GrL'Ca MailGuard» es un software de código abierto.
