Questions about this workflow
Will it verify every email mentioned in conversation?
Tell Notis in the instruction to act only when the message is a verification request, so casual mentions are not treated as tasks.
Can the result go back to Slack?
Choose the channel where Notis reports automation runs; the Findymail action itself verifies the address.
