Sorry for the confusion:
1. i created 2 automation but tested them one at a time
2. the alias to the team's inbox never delivered the message, but still I'm not sure if it's prefect that failed to send the email or the alias that failed to redirect because it's from prefect (although, the alias worked fine when sending a email myself), I tested these both by triggering flow and from the debug option
3. I switched to slack notifications and it worked great, I'll probably stick to this for now
