New Email Bounce and New Email Open, plus 1 more trigger
Can do
Send an Email and Send Email With Template, plus 1 more action
Works via
Native nodes, Webhooks, Polling, HTTP Request, JavaScript
Customizable with
field mapping, filters, branching, retries, dedupe logic, and custom API or JavaScript steps.
Capabilities
Triggers & Actions
Every event and operation available when connecting Postmark and Webhook — from both apps.
Production readiness
Production workflow controls
Use these controls when a workflow needs to stay stable after launch, not just pass a happy-path test.
01
Retry failed API calls
Automatically retry temporary failures before a run is marked as failed.
02
Handle 429 / rate-limit responses
Pause, back off, and continue the workflow safely when an upstream API throttles requests.
03
Add fallback branches for missing fields
Route incomplete payloads into a safe branch instead of letting the main scenario break.
04
Prevent duplicates with lookup-before-create logic
Check whether a record already exists before creating a new one in the destination system.
05
Use JavaScript to normalize dates, phone numbers, tags, and statuses
Clean and standardize values before mapping them into downstream fields.
06
Store execution logs for debugging
Keep a trace of what happened in every run so production issues are easier to inspect.
07
Route failed runs to email or a database
Notify the team or save failures for follow-up when a run cannot complete successfully.
08
Manually rerun failed executions
Replay a failed run after the issue is fixed without rebuilding the scenario from scratch.
