An email (short for electronic email) is a digital message sent from one person to one or more recipients. Emails are usually transmitted across the internet or other types of computer networks to transmitt information. In the Splinter Cell series, emails collected from data sticks are typically stored in the data section of the player's OPSAT.
Emails are used by individuals to send messages to other people, usually for private or personal reasons. In the Tom Clancy's Splinter Cell series, they can hold valuable information and can give special intel regarding the existing level, or providing background information on the story. They can also hold miscellaneous information that may not have anything to do with the mission at hand. In the early games, namely Splinter Cell and Splinter Cell: Pandora Tomorrow, players were able to collect data sticks that contained emails. Once collected from a computer, the player was able to view these emails in their OPSAT. In later games, like Splinter Cell: Chaos Theory and Splinter Cell: Double Agent, the player simply accesses computers and downloads the emails automatically to their OPSAT once they read them from the computer.
- After Splinter Cell: Double Agent, player-readable emails were removed from the games and haven't appeared in a readable format for the player to view.
