The business model depends on email-to-SMS gateways. I'm surprised more gateways aren't rate limiting or blocking you; my experience with these services is such that the providers really want you to utilize SMS instead, if you build up any sort of significant volume. I've certainly seen multiple providers delay this inbound mail periodically. Cheers, Al Iverson
