Throughout the day, I receive countless emails from various e-commerce sites who are trying to get me to spend money I don't have. Normally, I dismiss the notification on my smartphone, but when I open the Gmail app, I find all those unread messages waiting to be dealt with. Fortunately, Gmail has a way to quickly get rid of all those emails with one swipe.
The Gmail app on both Android and iOS has a powerful search engine that helps you find any email with a few keywords. Even more impressive is Gmail's ability to remember previous search queries for future reference. However, this list of past searches can become extensively long and needs to be reset from time to time.
For many of us, getting to inbox zero is the highlight of our day. But if you used your email address to sign up for various sites and services, your inbox is probably cluttered with all sorts of spam, news letters, and unimportant emails. Thankfully, Gmail has a feature that can solve this by using machine learning.
