On the Frontend: I want people to be able to enter their first name and their cell phone number and automatically receive my messages (auto-responders) for free.
They can also text a certain word and it will automatically add them to my mailing list and send them the autoresponder.
On the Backend: I want to be able to upload a large list of cell phone numbers (all over the world, not just United States).
I also want to be able to upload large documents such as novels or books and it automatically sends them one page at a time, or one chapter at a time until they ask for more or it can send it once a day. I'd love for these to be able to be sent out for free.
