Take 10 minutes to unsubscribe from email lists you no longer need. Scan all the emails you received in the last 30 days and click the opt-out link for any that you don’t feel excited to open. Or consider signing up for the free service Unroll.Me—that I have personally used and loved for YEARS. It stops unwanted emails from hitting your inbox and delivers a daily roll-up of the ones you DO want, so you can review them in less than a minute each morning.
