With thousands of unread email in Gmail, it was time to clean house. But just how do you select more than one screen worth of email at a time in Gmail?

As a product from Google, I should have known better – you use search. Yup, in the Gmail search bar, you do something like this:

older_than:1y

After the search is done, you can select all those emails using that checkbox above the email tabs then mass delete them.
