Labels. Letters do not appear in the folder, and are divided into categories that users can add and modify. The effectiveness of this mechanism is somewhat higher than the more traditional to the folders, as implemented by the possibility of combining different combinations of labels. There are “standard” icons, such as inbox (Inbox), or chats (chat). The possibility has not explicitly represented in the interface – to work with the combined marks the user must use a special syntax of the field “Search” (for example, to see all the history of the conversation with the labels friends, you need to type in search in: chats in: friends)
Archiving. With a large volume of e-mail boxes do not need to delete another message for the release of volume, enough to remove from them the label inbox (Inbox) to send them to the archive.
Autosave. When editing messages per minute is performed automatically save a draft letter, to prevent data loss in case of power off or other malfunctions.
Development of a list of contacts. For each interlocutor can be defined picture, address and phone numbers. Also implemented the substitution of addresses from the list that appears when typing in the line “someone” by username or email address dialed even partially.
Support for RSS. Because it can read the letter with the help of other RSS-client, for example, from personalized pages of search sites, msn.com, yahoo.com and most google.com, program Microsoft Deskbar. This makes it possible to check mail without connecting to the web interface.
Built-in spell checker. Automatically detects the language of communication, and offers alternative spelling words wrong.
Built-in chat. Messages can be delivered not only through the mail protocols, but also through the protocol Jabber, allowing users to exchange instant messages using a web interface mailbox program Google Talk, or any others that support Jabber.
E-mail to own domain. Ability to use when working with Gmail’s own domain name, and the creation of a large number of mailboxes, each of which can take advantage of Gmail. In this case for domains registered with the help of partners is not Google, would require special setup domain accounts. This feature is part of a service provided by Google – Google Apps.
Working in offline mode. Allows you to use your mailbox, even when not connected to the Internet. Offline access to Gmail using technology provided by Google Gears, which maintains the application on the user’s hard drive. In offline mode, users can read incoming messages, as well as write letters, which will automatically be sent immediately after the resumption of Internet connection.
