Hello there guys, I have been using Group SMS pro and Mass Text Personalizer, the problem with Group SMS pro is that I still have to pick all my contact one by one and then send out the text to all at once hence why I got the Mass Text Personalizer app which allow me to group my contacts alphabetically and this way I can send mass text to all group or individually group at once but the problem I am having with this one is that it always tell me that a large number of SMS is being sent, click ok to continue or cancel to stop and whenever I click ok, I will get the message that message could not be sent to recipients and none one will get the message. This is the same problem I go through whenever I use the app, sometimes, the app will send out text successfully to group A but after that no email will be sent again to any other groups without getting the same message again and again. Please can anyone recommend a better app or tell what I am doing wrong with the Mass Text personalizer as I wish to continue using it if I can find a solution the problem or get a better mass text apps recommendation.. Thanks very much in advance
