Using email aliases to test automated workflows

Testing an automated workflow can be a great way to ensure success when sending out emails to your customers. However, if you use the same email address each time when testing a flow, you may not be able to accurately test how the flow behaves when triggered. This is especially true if the flow's re-entry condition is set to "Never".

To avoid this, we advise using a different email address each time you test a flow. This will ensure that the flow is correctly triggered and that emails are sent when you test it.
