I used to be able to sort by sender or subject. Then I would select all and scan through to deselect some that I wanted to keep (like the most recent, or those that included info on orders, etc). Then I could delete all of the ones still selected at once. It was a way to get rid of large amounts very quickly. I haven’t been able to do that for a while and now have 50,000+ emails built up. Please bring back this functionality. I have considered upgrading, but won’t unless this is fixed.
