I'm looking for a way to monitor a gmail inbox and alert if a specific email is not received by end of day. the account is not user-owned (its a business email dedicated to this purpose) So I need a way to make this work without being "logged in" with a stored token(authorization can be granted the first time. or once every couple of months if needed).
I've checked out Pub/Sub but not sure if its relevant for my use-case or if its a bit of an overkill since I need only this one specific thing
