Send an email in Postmark when an issue changes status in Linear

What each client fills in

Postmark: From

For example Northside Plumbing <hello@northside.example>

Who it goes to (Postmark)

The address that gets it: yours, or the client’s team.

Linear: Team ID

Webhooks can be made only with an admin’s API key.

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.

• 

  In the client’s Linear: Settings → Security & access → Personal API keys → New API key. The triggers make webhooks, which needs a workspace admin’s key.

• 

  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.

After you install it

It lands switched off. The client’s checklist holds exactly this:

1. Connect the client’s Linear, for “An issue changes status”
2. Connect the client’s Postmark, for “Send an email”
3. Fill in Linear: Team ID (Webhooks can be made only with an admin’s API key)
4. Fill in Postmark: From (For example Northside Plumbing <hello@northside.example>)
5. Fill in Who it goes to (Postmark) (The address that gets it: yours, or the client’s team)
