External Services
This plugin can optionally connect to external webhook services to send notifications when emails are sent or fail. This feature is disabled by default and must be explicitly configured by the site administrator.
Webhook Notifications (optional, user-configured)
When you enable webhook notifications in Settings > Webhooks, the plugin sends HTTP POST requests to the webhook URL(s) you provide. The data sent includes: email subject, recipient, status (sent/failed), error message (if failed), and timestamp.
Supported services:
Slack — Terms of Service | Privacy Policy
Discord — Terms of Service | Privacy Policy
Microsoft Teams — Terms of Service | Privacy Policy
Generic Webhook — Any custom URL you configure. You are responsible for ensuring compliance with the receiving service’s terms.
No data is sent to any external service unless you explicitly configure a webhook URL and enable it. No analytics, telemetry, tracking, or other external calls are made by this plugin.

Frequently asked questions.
Does this plugin modify my emails?
No. The plugin only observes and logs emails as they are sent. It does not modify any email content or headers unless you use the forwarding feature.
Will this slow down my site?
No. The logging operation is lightweight and occurs within the normal wp_mail flow. Log queries are optimized with database indexes.
Does this plugin make external connections?
Only if you configure webhook notifications. In that case, the plugin sends HTTP requests to the webhook URLs you specify (Slack, Discord, Teams, or custom URLs). No analytics, telemetry, or other external calls are made.
Can I use this on a multisite network?
Yes. The plugin supports network activation and creates separate log tables for each site.
What happens to my logs if I delete the plugin?
By default, all data is preserved. If you want data removed on deletion, enable the “Remove all data when plugin is deleted” option in Settings > General.
Is the REST API secure?
Yes. All REST API endpoints require the manage_sendlog capability and WordPress authentication (nonce or Application Passwords).
What is the Trash feature?
Just like WordPress posts, deleted logs first move to Trash. You can restore them or permanently delete from the Trash view. Use “Empty Trash” to permanently remove all trashed entries at once.
Can I control which emails trigger webhooks?
Yes. Each webhook can be set to trigger on “All Emails” or “Failed Only”. You can also enable/disable sending notifications for forwarded emails per webhook.
