SMS Delay Group SMS & Multiple Schedule
When sending a sms to a large group it would be good idea allow a option to add a delay of between 15 seconds to 2 minutes as some mobile networks have issues when sending large no of sms in a short space of time.
Secondly it would be great idea to be able to schedule a message multiple times at the point of message creation.
I hope this feedback helps your team. I really love you app. Keep up the fantastic work :)
