At that rate you are already getting 1.5 cents per message or $15 cpm. Also, sending 10,000 a minute is easy. Delivering them is not. The cell co's dump messages after 5-10 per senders account so I would love to see how you are doing 10k and making $15 cpm (sending) and having all of those messages received by a user.
I am not trying to be an ass, just been doing this stuff since it started. In the beginning it was easier but since they wanted to charge per text, they were able to screw up the email to phone because they consider it a text.
If you have a list and a mailer you will seem to blast just fine. If you blast a list of addresses you control, you will see that after the first handfull don't get delivered and you don't get a bounce. Without a bounce you can't see when your ip/account is burned. If you did, you could write a sender that monitors bounces and tests and pauses or removes flagged ip's/accounts.
If you are getting 1.5 cents per message ($15cpm/$150 per 10k messages you are beating the market.
