# An email was sent directly

Guide: [Inbox API](https://docs.emelia.io/docs/inbox-api.md)

Webhook event `draft.sent`: Emelia sends an HTTP POST request to your URL.

Fired by direct sends only: `POST /drafts/send` and the direct send of the inbox app. Not fired when a saved draft is sent from the app, nor for scheduled sends, auto-replies or auto-forwards.

Registration: webhook subscriptions cannot be created with an API key, and Emelia has no screen for them yet: contact support.
