Trace Mail Log
This module provides detailed logging and tracking for all outgoing emails from your Drupal site. It captures the full SMTP conversation, allowing you to verify delivery and troubleshoot issues by viewing email statuses, server responses, and historical data in a dashboard. Integrations are available for Webform submissions, and enterprise-ready features like configurable retention and granular permissions are included.
Trace Mail Log provides complete visibility into your Drupal site's outgoing emails. It works with Symfony Mailer, Mail System, or Drupal core mail to capture every email event, storing the full SMTP conversation so you can verify delivery and troubleshoot issues.
Unlike simple mail catchers, this module doesn't just intercept emails—it logs them as they flow through your actual mail transport, capturing real mail server responses.
