Sending a message to users in a group

In the joomla contact manager I have defined group contacts E.G "Kindergarten Teachers"
I would like to allow users to open a contact form and send a message which reaches each teacher on that list.

I have created Email alias for the teachers which provides this functionality Via my ISP mail system. Can I do the same thing through Community builder without using the group address on the ISP?

Desired USER experience
Open contact -> Kindergarten Teachers -> Message form -> compose message -> press send button -> each user in the Kindergarten Teachers group is sent an email.

This functionality would reduce our Admin burden and simplify group mailing.

Thanks In advance.

CB has no mass mailing feature like that for frontend. Best I can suggest is maybe try using UddeIM as I believe it has a mass PM feature.
