Using Test Events
When you initially open the preview tab on the demo Welcome to Courier email, there will be a generic “Welcome Example” event with an empty profile. Any variables you insert into the template will not render until you add your own custom test event or update the JSON of the Welcome Example.
New Test Event
To send a test email or SMS via the Send Tab, you need to include an email and/or phone number in the
profile object of the test event JSON.
