Email all of your volunteers, ones on a particular mailing list or any group of them.
Emails go out personally addressed (e.g. Dear Sasha, Dear Paul)
Volunteers do not see the names of other volunteers on the recipient list but the administrator gets a copy of the email and a list of the volunteers is was sent to.
All replies go to the administrator who sent the message
You can create phone lists and mailing labels just as easily, and if you want, you can omit the volunteers that you have just emailed.
