Thanks, now I have to understand exactely what the product is, and what I would have to pay to twilio or any other gateway. To be honest, it's not clear for me, if I have to pay text to the gateway.

Hey ChristopheHK I hope I can give you some clarity my friend. With many text marketing platforms, you have to pay them monthly fees and they include a specific amount of messages. Most of those platforms purchase their phone numbers and messages through gateways like Twilio at a wholesale rate, and then they charge you more. For example, Twilio in the US is 0.0079¢ per message but other platforms may charge you 3¢ per message so they make their profit on the messages.
With Rockstar SMS, you can go set up a free Twilio.com account and then connect your Twilio account to our platform in less than 3 minutes using our easy-to-follow Tutorial Videos. That way you can get your phone number and messages at wholesale prices.

So our platform gives you the ability to have text conversations with customers as well as building a text list and sending bulk outbound texting and best of all, you only pay us the one time price here on AppSumo.

I hope that answers your questions. Please feel free to ask if you have any others!

Yes it does.
