I need to have a web sms platform that will allow customers to send large numbers of sms text messages to different opted in groups of people through the web.
There are a number of paid services that offer the functionality I'm looking for such as [url removed, login to view] and [url removed, login to view] but I'm wanting to have program made that will run on my server and wont require me to pay per message sent using short codes.
The specific functions I need are:
The ability to white lable the program
The ability to have multiple groups of mobile numbers
The ability to import mobile numbers into each different group from a csv or excel file
The ability for people to add themselves to different groups by sending a text message with a keyword to a phone number we can provide them (Just like when you see company's say "Text Signup to 213144"
The ability to send text messages to each group through a web based user interface
Mobile coupon creation
Automated Billing/Credit card processing
Ability to optin from web page or fb or twitter\
I want this platform to be expandable to be able to include future marketing solutions like email etc.
