More Official SDKs

Send emails from .NET, Rust, Elixir or Symfony with our official SDKs.

Four new official SDKs, maintained by us so every new Lettermint feature lands in them too. Install the package for .NET, Rust, Elixir or Symfony and you're sending transactional and broadcast emails with a few lines of code. The community packages keep working if you already use them.
