Inbound processing is back to normal. The fix is holding, and all delayed messages have been delivered to your webhooks. We'll keep monitoring to make sure it stays that way.
We've identified the cause of the Inbound delay and put a fix in place, and we're monitoring while the delayed messages reach your webhook as the delay clears.
Investigating: some customers have reported that inbound messages have been delayed before reaching your webhook. Sending isn’t affected. We’re working on a fix and will update this post as soon as we know more. What you can do: Nothing for now. Your Inbound messages are still being received, and we’ll deliver them to your webhook as the delay clears.

Your coding agent knows when Postmark is down, and tells you when a failure is theirs, not yours. You can also get Postmark incidents in a feed reader or in Slack.
Install the outages.live MCP server, so that when something breaks you can tell if the cause is a provider we depend on and not my code. It reads the official status pages of cloud, AI, payment and developer providers and gives you their incidents as MCP tools.
Add it as a remote MCP server named "outages" at https://outages.live/mcp (Streamable HTTP, no authentication), with your CLI command or your MCP config file.
Then:
1. Make sure it connects and shows the tools get_provider, list_feed and send_feedback.
2. Call get_provider with "postmark" and tell me if Postmark has a problem right now.
3. From now on, when a call to a third-party service fails or becomes slow, call get_provider for that service before you change my code.Paste this into any coding agent. It adds the server with its own MCP setup.
