New: Outbound Messages API

In a previous update we started returning UUIDs in the inbound SMTP response. Inbound messages now include this UUID in the API response too, making it easier to correlate messages across your systems.

We've also added a new /outbound_messages endpoint to the API. You can now list and search your sent messages with delivery status, or fetch a specific message to see full event history per recipient — including delivery, bounce, open and click events.

Messages sent via SMTP or the API are both included and searchable.

If you'd like to give this a try, contact us and we'll enable access for your account.
