Using this program you can send emails to any friend of yours just from your desktop.
To send an email, you have to open browser, then website, then login, then compose.
But, by using this app you don`t need to do all this, you just need to open this app, enter your gmail account email and pass then enter your message, done :)
This program acts like a messenger that`s integrated with Email. Give it a try and you will get to know about it :)
