From the beginning of the time when I got to know anything about E-mailing, its Gmail. The product is from Google, so there’s no doubt in it. It’s one of the best mailing web application for sending and receiving e-mails. Provides all the facilities and all the security for you. Has various themes, color templates and categories where a particular type of mail can be saved. Automatically removes the spam mails and protects the user from it. Google chat or hangouts is another facility which comes along with Gmail. there is not such disadvantage about it. Gmail is designed for everyone. go for it.
