email productivity

Email is arguably the most popular form of communication to date, especially with almost everyone adopting a remote work setup. In fact, the number of private and business emails sent per day worldwide in 2021 alone has hit 319.6 billion, and this is expected to rise further to 376.4 billion per day by 2025. Email usage penetration in the U.S. is at 90.3%, with a whopping 76% of U.S. workers still checking emails beyond work hours and the average person sending and receiving 121 emails per day.


What all these numbers tell us is that there is no escaping email. Fortunately, there are apps that make handling the ever-growing barrage of messages much easier. We've listed some of the best email productivity tools to help you find the best fit for your usage style.

Lightkey is an AI-powered software that not only suggests corrections for your spelling and grammar as you type, but it can also predict the next 12 words ahead, including punctuations.

If you spend lots of time composing emails or even typing out documents, Lightkey can help speed up the process by helping to reduce your thinking time. There's also less need to lift your fingers off the keyboard and hit the backspace button as its spelling correction feature works while you're typing.


This user-friendly email productivity software makes a practical addition to anybody who does any type of writing. With its seamless integration with your preferred email app, you can start boosting your productivity and actually spend less time on your inbox.

Boomerang is a great email productivity tool for helping you reach inbox zero.

Zoning out of your emails for a while is a practical email productivity tip, but willing yourself to do it might be challenging. If you really want to do it definitively, the software lets you snooze the arrival of new emails too.

3. Superhuman
