Incoming mail messages for a user may be ranked, modified, and/or summarized based on a number of factors, including characteristics of the user computing devices used for accessing email and the user's current context. User context may include location, whether the user is currently driving, how much time the user has to read email messages, etc. Features of incoming email messages are analyzed, including length, attachments, sender, etc. User-related activity and characteristics of the user's computing devices are determined and analyzed to determine a user context, for instance, the user's location, mode of movement, time slot available for the user to read email messages, upcoming events on the user's calendar, etc. The email messages are then ranked according to the user context and/or user computing device characteristics. At least a portion of the email messages are provided for presentation via a user computing device based on the ranking.
