Why Should I Use an Email Client?

Ask yourself how much time you spend opening, reading, and replying to emails every day. Most likely a lot more than you’d like. One reason why most people spend too much time managing emails is that we simply receive too many of them. The average office worker, for example, receives around 120 emails per day, according to recent statistics, and the number is growing year by year.

A good email client for Mac helps you reduce the time you spend on email management with features like keyboard shortcuts, filtering, snooze, and others. If you can save just 30 seconds per email by using the Mac default email client, you should be able to spend an hour less on email management every day.

And if you can also reduce the number of emails you receive by using an inbox cleaner with automation functionality, such as Clean Email, you might not have to spend any significant amount of time on email management at all.
