Clean up your inbox by unsubscribing from lame lists
Most of us are still subscribed to email newsletters that we haven't actually opened since 2011. Now's the perfect time to cut yourself free from the dead weight clogging up your inbox. Thankfully, the site Unroll.Me makes it incredibly easy to unsubscribe en masse. Just sign up via the affected email address, follow the prompts, and remove your name from any and all lists you no longer want to be on.
Furthermore, if you're curious what random sites, accounts, apps, or services you've randomly signed up for over the years using your Gmail address, deseat.me will do a thorough search, and help you disable any and all you no longer want to have your info.
