I have found email-to-SMS gateways work very well in the US. There were hiccups initially (10 years ago), but now they are rapid and delivery is reliable. For medium-volume, I like it that they are free to the sender.
Yes, you have to ask each recipient in advance who their carrier is, in order to correctly address the message. I have not found any automated solution that “discovers” the carrier corresponding to a phone number.
I have also found that outgoing SMS (was) is limited to about 10 messages per second by some US carriers, so be aware of this if you are attempting to send via an actual phone connected to a computer. This was true more than 5 years ago, which is my last datapoint. Because of the way SMS is actually carried on the cell network, this may in fact be a limitation of the available SMS bandwidth for a single phone. That’s why we switched over to email-to-SMS years ago.
