As we've announced before the new iteration of Newsletter Studio will run on both Umbraco 8 and Umbraco 9. We're in the process of migrating parts of the package to .NET 5 and we've come a long way.
We have an RC (Release Candidate) out that has the same features and core-API as the Umbraco 8-version.
Trying out Newsletter Studio for Umbraco 9
The RC is out in the wild and you're most welcome to try it out. Since Umbraco 9 only support package installation via NuGet you need to install the package this way.
Install using NuGet
We've made the package available on NuGet, at the moment when the package is in RC one needs to enable "Prerelease" packages to see it.
dotnet add package NewsletterStudio --version 4.0.2
Once you've installed the package, take some time to look at the documentation.
Known issues and feedback
The Umbraco 9-version is built on the same code and Core as the stable Umbraco 8-version so at the moment there are no known issues.
