    45 days worth of full content history by default to help you troubleshoot (customizable from 7 to 365 days if needed).

    Keep track of bounced emails through the web dashboard, or use web hooks to notify your app of any issues.

On top of all the tracking info, in almost four years with Postmark, I can’t remember a single time an outage impacted our business.
