In order to trigger when emails are opened, this must be paired with a separate Zap using the **Send Outbound Email** action, with the **Enable Read Receipts?** field set to `True`.

To test with a live email, send an email to yourself using your **Send Outbound Email** action (with read receipts enabled) and open it, then test this trigger immediately for samples. If you don't need to test with live data, click Skip Test to use static test data.
