Sorting your inbox is one of those necessary evils and while the default iOS Mail app doesn’t have a ton of options for doing so, it does have a few clever perks. OS X Daily points out that one of those the slightly hidden away attachments mailbox.
As the name suggests, the Attachments mailbox shows you all the emails you’ve received that include attachments. It sounds simple, but it’s a surprisingly useful box to set up to quickly find what you’re looking for. To set it up, simply open up Mail, tap the Mailboxes button, then Edit. Here, you’ll see an option to enable “Attachments.” Enable it, and you’ll always have quick access to any email you’ve received with attachments. If you’ve never messed around with this menu, it’s worth looking at some of the other sorting options in case there’s anything else that’s useful to you.
