Premail version 2.0 is out! Take a look at npm or GitHub.
Compared to where this started, Premail is a completely new tool with a new name, so this is really more like a v1 of a full-featured tool.
And, transparently, there are still some known bugs. I'm going to try to create issues for these in the coming days, but I wanted to get a v2 release out the door so that the npm package could be properly updated.
More to come!
