Frustrated X2 – Mass Text Message Review

I purchased this app 2 times! I send M-F a bible scripture/encouraging WORD to over 1000 people. People have been waiting for their daily encouragement, which I'm not able to send. When the names show up green it works but not always. If my group shows up blue it will say a recipient must be removed because of iMessage. I've tried everything... NOT WORKING! Can anyone recommend another app to send Mass Text? Thanks
