Hi, I am looking for either an email or web service or app that I could send a text from my iPhone to a group consisting of approx. 20 people. I have looked on the app store and have found apps such as Groupme, but am looking for one with one sender (me) so not everyone can reply within the group. This can be annoying when many people can respond to everyone in the set group - more just to get the word out to many people at once. Is there any app/service or easy way to do this? I realize I can send out text groups but would rather do something more official that's a mass text from a service with number. Thanks for the tips.
