Many small organizations, churches and youth groups cannot afford the high priced group messaging services that many companies offer. Telefio Messaging offers a free group messaging service for small youth groups and churches.
Telefio is really nice because it has all the features that you need to notify your subscribers/members and the really cool thing about it is that it’s totally free. You can see how it works at http://telefio.com/how_it_works. I would recommend it to youth leaders, church leaders, small groups, ministry groups, worship groups or just anyone that needs a cheap (or free) group messaging service to keep in touch with his or her group.
