Disclaimer: I do a bit of part time dev evang for Nexmo.

Nexmo should be pretty good across the board as it pertains to what delivers best (direct to carrier model: http://blog.nexmo.com/post/4690069179/directsms). In that way, Nexmo is trying to solve the issue you're having.

Have you had any issues with deliverability and Nexmo (where another provider delivered better)? Nexmo actually provides some tools to automatically optimize traffic based on client conversion ratios.

I haven't had very good luck with Nexmo and deliverability. I wanted to migrate all my traffic there, but had to stop after a few %-tests resulted in increased failure rate. I do still use them for some areas/networks they seem to do better with. I also appreciate their good customer service.

I'm sure the team would appreciate the feedback as to where the deliverability was less than another provider. Also, might want to ask about the recently added tools to use your conversion stats to help route traffic.
