I'm writing an application that needs to send out SMS and MMS messages
to users, and was wondering if anyone has experience with bulk carriers
and messaging gateways. The application is based in the US, and the
messages are for US-based users.

If someone could provide insight on the following, that would be great:
- 'all-you-can-use' plans for sending bulk SMS/MMS messages
- names of bulk messaging providers
- names of messaging products that you have experience with

Thanks in advance for any help and insight you can provide! I have
investigated several 'pay-per-use' carriers, and some messaging
gateways, and was hoping for first-hand insight.
