• Answer:

  ☛You can mark all your mails as read by following these steps listed below▼ →Click Options, ‘Mail Options’ at the top right of your Yahoo Mail page. →Click on ‘General Preferences’. →Go to the "Message Results per page section. →Click the Blue down arrow and select 200 (maximum). →Go to the bottom of the page and click ‘Save’. ☛Go back to your In-Box page and scroll down to the bottom of the first page.
