File type of Previews

[Michael Render]

I would like to use the new Previews functionality in the latest release, and I pieced together how to use it by looking at the tests in the relevant commit.

However, the tests only check the bytes are not null, and I'm not sure how to work with it. What file extension does it correlate to?

Thanks!

Hey @RenderMichael sorry about the ambiguity, they are .png files, more information on how to write to disk here: https://mailosaur.com/docs/email-previews
