That’s not how you use it, in the auto command name in your delay action type Send Email and set the delay to 1 for 1 second
Then remove the test email action and save that rule
Now create a new auto command executed rule
Add constraint for auto command equal Send Email
Then add your test email action
That should work, if not set the delay number higher in the other rule as it may take longer than 1 second to complete process before then sending the email command
