Send an email in SendGrid when an email bounces in Postmark

What each client fills in

SendGrid: From address

For example hello@northside.example

Who it goes to (SendGrid)

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

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.

• 

  SendGrid → Settings → API Keys → Create API Key with Mail Send access; for the triggers, also the Event Webhook settings permission (user.webhooks.event.settings.read and user.webhooks.event.settings.update), or Full Access. The From address must be a verified sender.

After you install it

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

1. Connect the client’s Postmark, for “An email bounces”
2. Connect the client’s SendGrid, for “Send an email”
3. Fill in Postmark: Message stream (The stream the emails go out on: “outbound” unless the server has others)
4. Fill in SendGrid: From address (For example hello@northside.example)
5. Fill in Who it goes to (SendGrid) (The address that gets it: yours, or the client’s team)
