Service Connect - testing an email Output Channel

Hi All,
We’re looking to change our current email relay setup and one of the last things on the list to move is the Service Connect setup
I’ve created an Output channel to use the new relay, but I’ve got no idea (and it’s not obvious) how to go about testing that it actually works correctly
The email output channel is used very rarely as it’s only used when we have an error (so it’s not used often, but when it is used it’s kind of important)
Is there a way to test this new Output channel, that doesn’t involve waiting until the Output channel is used and hoping that it works?

I know very little about SC, so the most idiot proof way to test this would be great :slight_smile:
