First of all, thanks very much for the help. Genuinely good thinking and it took me a while to get to that point last night.
Here's the problem: each time the webhook activates, that's an operation, so it might activate the webhook 100 times for one call. The problem is not that it won't send a properly formatted email at the end. It's that it wouldn't continuously active the webhook when its running with one single assistant, but when connected to squads, it continuously jams data through that Make is having to receive. Once Make receives the data, that's an operation. So to run 10 calls, it might take 1,000 operations where it should take 20 or 30.
