Personally I won't do that as LLM's way of judging an unimportant email vs my judgement is different - we are still working on evolving that but again email is so different for different people that it will need a lot of learning.
But you can say remove all the emails which have unsubscribe text and it will do that in the batch of 20-100 (based on the app's rate limit at that time)
