This is going to be short. Sweet. Perhaps a bit life changing if you get piles of emails.
Do you open your inbox each morning to dozens (yes, plural) of emails?
Do you receive marketing emails? Especially some that you wouldn't have a clue where they got your email address?
Do you get continuous flows from LinkedIn for all the varying reasons of connections, conversations, endorsements?
All these are irrelevant to your daily work flow. Yet some you might want to look over, at some time.
