Mass-notification system and method

At least one non-transitory computer-readable medium comprising instructions that, when executed on a computer system, cause the computer system to disseminate messages from a first tenant to a plurality of recipients, including performing operations to:

• generate a first event data structure that includes a first message and a first set of recipients for the first message;
• place the first event data structure on a first topic channel of a plurality of topic channels;
• generate a second event data structure that includes a second message and a second set of recipients for the second message;
• place the second event data structure on a second topic channel of the plurality of topic channels;
• by a first contact method handler of a set of automated contact method handlers, subscribe to the first topic channel and to the second topic channel;
• and
• by a second contact method handler of the set of contact method handlers, subscribe to the second topic channel;
• read, by the first contact method handler, the first event data structure from the first topic channel, and format a first message for transmission to a first mass-communications service provider to notify a first portion of the first set of recipients by a first mode of communication;
• read, by the first contact method handler, the second event data structure from the second topic channel, and format a second message for transmission to the first mass-communications service provider to notify a second portion of the second set of recipients by the first mode of communication;
• and
• read, by the second contact method handler, the second event data structure from the second topic channel, and format a third message for transmission to a second mass-communications service provider to notify a third portion of the second set of recipients by a second mode of communication that is different from the first mode of communication.

An automated system for disseminating messages from a first tenant to a plurality of recipients, the system comprising:

• a processing system including at least one processor and memory;
• and
• wherein the memory comprises instructions that, when executed, cause the processing system to:
• generate a first event data structure that includes a first message and a first set of recipients for the first message;
• place the first event data structure on a first topic channel of a plurality of topic channels;
• generate a second event data structure that includes a second message and a second set of recipients for the second message;
• place the second event data structure on a second topic channel of the plurality of topic channels;
• cause a first contact method handler of a set of automated contact method handlers to subscribe to the first topic channel and to the second topic channel;
• and
• cause a second contact method handler of the set of contact method handlers to subscribe to the second topic channel;
• cause the first contact method handler is to read the first event data structure from the first topic channel, and format a first message for transmission to a first mass-communications service provider to notify a first portion of the first set of recipients by a first mode of communication;
• cause the first contact method handler to read the second event data structure from the second topic channel, and format a second message for transmission to the first mass-communications service provider to notify a second portion of the second set of recipients by the first mode of communication;
• and
• cause the second contact method handler to read the second event data structure from the second topic channel, and format a third message for transmission to a second mass-communications service provider to notify a third portion of the second set of recipients by a second mode of communication that is different from the first mode of communication.
