Like Internet forum (message board), email (Electronic mail) has been active from the beginning of Internet until now. As a result, we all rely on email for our work and communication to some extent. Thereinto, the free, powerful and friendly Gmail has always been the leader with the most users in the world. But even so, using it on computers and mobile phones has many inconveniences. For instance: all web browsers should enable JavaScript and Cookie features; sometimes you may inadvertently shut down an email page you are editing inside; and no one likes to use Gmail in the browser on a phone all the time.

The advantage of using an email client is that you don't have to open a web browser and log in to your mailbox every time; supports for new email reminder; allows to send emails to third-party applications (e.g., Evernote, Todoist, etc.), and so forth. Therefore, users who need to send and receive emails frequently always tend to use a desktop email client, rather than any web browser.
