Required software development freelancer for Need help unblocking our emails job

I run a small educational and sales company servicing holistic medical practitioners. Recently several major email providers have been blocking our emails. The domain that is being blocked is eastwestmed. I send from dstarwynn at eastwestmed. The blocking providers we are aware of include aol, sbcglobal and live.com, although there could be others we are not aware of. I need someone with experience in communicating with these companies and doing what is needed to get our email off their block lists. Also to research to see if any other major email providers are blocking our emails.

We do not spam, everything sent out from eastwestmed is educational and we only send to people who have opted in.

Thanks
