Messaging systems with improved reliability

Abstract:

Improved messaging applications are described that use a first set of software to test rendering of a message, and if the test is successful the message is allowed to be presented. In one embodiment, a first set of software can attempt to test the renderability of a message and if the test is successful, the message can be stored in a message database. In one embodiment, the first set of software operates in a separate sandbox from a sandbox for a messaging application which displays the message. The first set of software can operate in a first process which is different than a process in which the messaging application runs.
