Sorry if this isn't the right place to ask a question however it didn't seem to fit anywhere else and will eventually evolve into a workorder.

Our print campaign designer is working on a few different things for us and I wanted to ask him to develop a template email 'skin' which is consistent with some of the other items he's developed for us. So here is my question...

If our designer creates a general email skin, what format/file type would you prefer the skin to be 'delivered' to you if we wanted it incorporated into the CMS emailer at some point?

Please let me know what options would work so I can pass this info along to him.
