Postmark
· #342 most-usedSend transactional email that reliably reaches the inbox
Postmark is a transactional email delivery service built for speed and inbox reliability — optimized to get triggered emails (receipts, alerts, onboarding sequences, invoices) into the primary inbox, not the promotions tab. Connect it to Actionist and your agents can send individual and template-based emails, react to bounce and inbound events within about a minute, retrieve delivery status and message content for compliance records, and monitor deliverability health across sending domains — all without anyone logging into the Postmark dashboard.
Eliminates manual work. Agents eliminate manual bounce scrubbing, inbound email routing, delivery confirmation retrieval, and dashboard monitoring — tasks that typically happen after every campaign and require navigating multiple tools.
What your Postmark agent runs on autopilot
A week of scheduled jobs your Actionist agent will execute on your behalf.
Postmark × every other app you use
End-to-end automations that span multiple apps — each one a real business outcome.
Customer reply to email becomes a routed support ticket in seconds
When a customer replies to a Postmark-delivered email, the agent parses the inbound message, creates a ticket in Notion with the full reply context, posts a routing summary to the #support Slack channel, and sends the customer an automatic acknowledgment via Postmark's Send Email With Template — all within about a minute of the email arriving.
Time saved for your team — every week, on autopilot

What your agent runs for you

How to plug Postmark into Actionist
Pick the connection method that suits your environment.
Connect Actionist to Postmark using a Server API Token. Each Postmark server has its own token, so if you send from multiple domains on separate servers, create one Actionist connection per server.
Log in to Postmark and go to the server you want Actionist to use. Navigate to API Tokens in the left sidebar.
Click Generate New Token, give it a descriptive name (e.g. 'Actionist'), and copy the token. Treat it like a password — it has full access to send from this server.
Paste the token into the Server API Token field in Actionist and click Test connection. Actionist makes a lightweight API call to confirm the token is valid.
