Failed Email Alerts

About this Plugin

Listens on the wp_mail_failed action to detect every email delivery failure. Failures are logged to a custom database table with time, recipient, subject, and error message. Alerts are dispatched via a configurable fallback channel — WordPress admin notice, direct PHP mail(), or a Slack/Discord-compatible webhook — with a cooldown to prevent alert floods.
