Hi
Yes this is possible without any problem.
Of course the recipients would need to opt-in for this service. You can only send messages to connected users.
If a user is not yet connected to your Rogerthat service, you will need to invite him. There are 2 possibilities
* User is not yet a Rogerthat user. He will receive an email
* User is a Rogerthat user. He will receive a Rogerthat message containing an invitation to connect to your Rogerthat service
