The ability to effortlessly and quickly send a voice, video, picture or email to a whole group of people at once is amazing and makes this app worth every penny. I use it weekly to send voice or video messages to all my group members. At first, the mail app rejected all addresses from the group, even though I knew they were all correct and valid. Then I discovered that my list of nearly 200 names was above some arbitrary secret limit. I divided the group in half, and now I send 2 identical messages, each to a subgroup, with no problem. The reaction has been very favorable and i would highly recommend this app to anyone with an iPhone who wants a quick, easy, almost foolproof way of sending messages to any one, or group of ones simultaneously (use BCC), NOT SEQUENTIALLY, from anywhere there is a cellular or data connection.
One request: keep voice memo or video in a queue for easier repeated sending of same message file to individuals or groups, even at separate times after quitting or suspending of app.
