Example workflow: Send a welcome email when a contact is created
Section titled “Example workflow: Send a welcome email when a contact is created”Here's a simple workflow you can build with the Resend nodes:
- Resend Trigger: listens for
contact.createdevents. - Resend (Email > Send): sends a welcome email to the new contact using data from the trigger.
The Trigger-Action pattern works for any event. For example, you can notify your team on Slack when an email bounces, or log delivery events to a spreadsheet.
