SMS will get blocked by telco once they see the same messages being sent to their network from the same number. Your best option is to rotate the sender number and telco to avoid block. Commercial online services will not be able to assist for this. The work around is to get people to sms your designated opt in number (forget the terminology for this, maybe someone can fill this?) with a "PIZZA" to activate the opt in. This way telco will be able to recognise that the receipent has requested your marketing messages and allow your message to reach them without block.

For blackhat ways, you need to have a custom bot and multiple sim cards reading device to automate the sending through telco/sender rotation. Each number should not send more than 30 messages every two hours to avoid blocking.

We know of a new system that is totally spam compliant that allows you to send sms to people that have not opted in.
