- An email from the server bounced (a bad address, a full inbox), within seconds.

What each client fills in
- Slack: Channel
- For example #leads or C0123456789
- Postmark: Message stream
- The stream the emails go out on: “outbound” unless the server has others.
The accounts it needs
Each is the client’s own, stored encrypted and never copied between clients. Until one is added the client’s checklist shows it, and nothing runs.
Postmark → the client’s server → API Tokens → copy the Server API token. The From address must be a confirmed sender signature or on a verified domain.
In the client’s Slack: api.slack.com/apps → Create New App → OAuth & Permissions → add the chat:write scope (and channels:history, plus groups:history for a private channel, for the message trigger) → Install to Workspace → copy the Bot User OAuth Token. Invite the app to the channel.
After you install it
It lands switched off. The client’s checklist holds exactly this:
- Connect the client’s Postmark, for “An email bounces”
- Connect the client’s Slack, for “Post a message”
- Fill in Postmark: Message stream (The stream the emails go out on: “outbound” unless the server has others)
- Fill in Slack: Channel (For example #leads or C0123456789)
