If you have a program that sends an email with fixed content to a fixed email address, whenever you run that program that email address will receive an email.

If you have a program that sends an email with fixed content to a fixed email address, whenever you run that program that email address will receive an email. Is the email an output, or a side-effect?

It is an output or, in FP terms, a side effect. But you're discussing semantics here while it's obvious side effects mean different things in different contexts so the conversation won't get very productive.

Sending an email absolutely involves IO.
