Transactional email send + 6 deliverability triggers from Postmark

Postmark is the transactional-email service developers pick when deliverability is the absolute priority and they're willing to pay slightly more for that focus. Six triggers cover the deliverability events that matter, more than any other email connector in this catalog: Email Delivered (the receiving server accepted), Email Bounced, Email Opened, Link Clicked, Spam Complaint (a recipient marked it as spam, critical signal for list hygiene), Subscription Changed (subscriber added or removed a list subscription). Three actions: Send Email (custom HTML/text), Send Template Email (using a Postmark template), Get Delivery Stats (open rate, click rate, bounce rate over a date range). The integration uses a Postmark API token (Server-level for one server, Account-level for cross-server operations). Postmark's separation between transactional and broadcast sending streams means workflows can route the right kind of email to the right stream automatically, order receipts via the transactional stream, marketing nudges via the broadcast stream.

Before you build

Three things worth knowing.

Filter at the trigger

Tiny Command counts a run the moment a trigger fires. Filtering early means only matching events spend your usage budget.

Authorize once, reuse anywhere

Connect Postmark once and every workflow on your account can use its triggers and actions. You don't have to re-auth per workflow.

No JSON to read

Every Postmark field shows up in the visual picker for downstream nodes. The raw payload is there for power users, optional for everyone else.

FAQ

Questions about the Postmark integration.

If we missed yours, ping support. We usually reply within an hour.

How do I connect Postmark to Tiny Command?

Open the Tiny Command workflow builder, drop in a Postmark node, and click Connect. Authorize Postmark once and any workflow on your account can use its triggers and actions. Most teams finish the connection in under two minutes.

What Postmark triggers does Tiny Command support?

Tiny Command supports 6 real-time Postmark triggers, including "Postmark Email Bounced", "Postmark Email Delivered", "Postmark Email Opened". Each trigger fires within seconds of the event happening in Postmark.

What Postmark actions can I run from a workflow?

3 Postmark actions are available out of the box, covering email operations like "Postmark Get Delivery Stats". Every action accepts dynamic inputs from upstream nodes, whether that's a search result, an AI output, or a form field.

Is the Postmark integration real-time?

Yes. Postmark Email Bounced and every other Postmark trigger uses webhooks or push subscriptions, so workflows fire within seconds of the event in Postmark rather than on a polling schedule.

Do I need to write code to use Postmark with Tiny Command?

No. Every Postmark trigger and action is fully configurable from the visual workflow builder. For edge cases that aren't covered, drop in a custom HTTP node and call any Postmark API endpoint directly.

How much does the Postmark integration cost?

There's a free tier you can start on without a credit card. Higher run volumes and team features come with paid plans. The Postmark integration itself has no per-app surcharge.
