I can’t believe this feature does not exist yet, but in Yahoo mail you can’t delete all the mail messages you have in a folder (in my case 28,000!). You have to delete 200 at a time ugh.
Yahoo Mail group:
1. Can you make it so I can see like 500 or 1000 email per page?
2. Can you add “Delete All Messages In Folder” option?
Please please.
