Tamish Ashwani - Self Promo Mailer. I like how he's used the flow of the folding technique to guide the viewer through the process.

Not exactly a mailer but the techniques used could be transferable. However this is a one off, to reproduce 5 different copies would be a painstaking task, something I need to bear in mind considering the timescale of this brief. 

The above 3 folding technique examples are taken from the book 'Mail It' by Pepin Van Roojen and could be useful due to their size and rectangular finish.
