I bought Sendy yesterday. Managed to tweak it to make it successfully run on Windows Azure (yes we are aware its not supported). We plan using Sendy as back-end and use its functionality (via REST APIs) to make the functionality available through our .NET application, thus making it immaterial as to where sendy is hosted. Even In long run, it would be difficult to keep managing upgrades on Windows (unless you decide to release a version for Windows).
So I would like to know the roadmap for Sendy and its API and also I am thinking to get Sendy installed and configured on Azure Linux VM. We have no experience with Linux and wondering if someone can help us.
