Systems and methods for transmitting a communication based on a device leaving or entering an area

Location information associated with a computing device may be received by a server. For example, the location information may indicate the current physical location of the computing device. The server may compare the current location of the computing device with a set of locations associated with the computing device. The comparison may result in a determination that the computing device has entered or left a location area. In response to such a determination, a communication may be transmitted to a user of the computing device. For example, an email may be transmitted to the user. The email may include information describing that the computing device has entered or left the location area.
