# Postmark

> Use Postmark in Workflow Machine for transactional email workflows and reliable outbound message delivery.

## What Postmark is good for

Postmark is useful when a workflow needs to send transactional email as part of a larger process.

Typical use cases include:

* acknowledgment emails
* follow-up notifications
* templated operational messages
* system-generated outbound updates

## Common workflow patterns

Postmark is a strong fit for:

* support confirmation workflows
* transactional status updates
* templated email delivery
* workflow-generated customer communications

## Triggers and actions

Postmark workflows usually focus on sending email or sending email from templates. Check the step picker for the exact Postmark steps available in your workspace.

## Connection requirements

Before using Postmark:

* create a Postmark connection
* confirm the correct sending account or server context is connected
* verify the workflow should use that outbound email setup

## Troubleshooting tips

If a Postmark step fails, check:

* whether the connection is valid
* whether the template or recipient data is correctly mapped
* whether the workflow is sending the expected fields and content
