So this give very little info on how the bulk email deletion works.

For instance at last look I had north of 40k emails from ebay. I can't just delete them all as I want to keep anything that is related to either an order I placed or an item I sold. I have went back 15+ years before to find part numbers before.

But I have no interest in the 38000+ marketing emails from them. (I kinda wanna keep getting them but don't want them a week after I get them.

And if I recall correctly the emails have often come from the same accounts so I can't even filter by that.
