In prior years, this annual series covered individual apps. This year, we are looking at all-in-one solutions in addition to strategies to help in 2021. Welcome to day 2 of 21 Days of Productivity in 2021. Like many of us, I have a love/hate relationship with email.

Email was, and still is, one of the primary means of electronic correspondence. It is used for business communications, commerce, notifications, collaboration, and a pile of useful things.
