I've used our custom font (as an image) for headlines and titles our custom font for our email newsletter. Though not an email best practice, as an almost imageless email the font goes a long way in branding the publication.
However, the images are rendering the text a bit askew as though they were typed on an untuned typewriter.

Is this just a Litmus thing? Any suggestions/experience on fixing it in the community?
