Organize Your Labels
Using labels is a great way to organize your emails, but as the number of labels grow, they too may need organizing! Lucikly, Google makes this easy to do in Gmail.
Navigate to the Settings section (found withing the gear icon) and select Labels. This will show you all the default labels plus the ones you’ve created over the years. If you wish to keep certain labels to archive your mail but don’t want them cluttering up your inbox, click on Hide and they’ll disappear from view.
You can also select which ones are viewable in IMAP. One in particular you may want to hid from view is All Mail, especially if you’re setting up a new IMAP account in Thunderbird or Outlook for an email address that’s been collecting email for several years.
