Mass Messaging in BuddyPress, is pretty much the opposite of the alternative Mass Messaging plugin – Mass Messaging for BuddyPress by Alkaweb. What I mean by this is this; whatever Alkawebs plugin does in the back-end, Mass Messaging in BuddyPress does from the front-end. Both of these plugins allow site admin to send mass messages to all, or groups of users in BuddyPress. What Mass Messaging in BuddyPress does extra, is to provide the ability to allow that privilege to other user types, and also it has the ability to track if the message has been read.
