I want to offer a service to users so that I can disseminate messages which will be "fanned out" (sent to multiple users at the same time.
Ideally the features would include:
- offers an api to integrate in my development environment
- offers a web application to use within a browser
- offers mobile apps for Android, ios great but not a must
- need to be able to fan out messages to multiple users at the same time, one way traffic from my end to the users is sufficient
- users should not know about each other, hence a group chat is not desirable.
- the message content is text based but images would be of additional value to potentially disseminate charts in the future
- it should be easy for me to add new users to my messaging service.
- as there could me dozens of hundreds of messages per day email is not a viable alternative.
The purpose of this service is to disseminate messages to potential future clients.
Initially I prefer an open source or free service as this is a startup and is not run on a commercial basis yet.
