I just published a big post on our company blog about how we came up with our priorities and roadmap for Postmark for the next few months. From the intro to How we built a product vision and roadmap:

So, armed with some whiteboard markers, a mountain of sticky notes, and one very enthusiastic team, we set off to plan out the next few months of our product.

This one took a while to write and edit, and there’s some nice illustrations as well as downloadable templates, so take a look!
