this may be an odd post, but here it is :).
I really like mailbox.org, its focus on open-source and privacy, its reasonable prices etc. That's why i want to suggest that a marketing/PR bureau have a good look at mailbox.org. I think a the moment its design is very pleasing to tech-enthusiasts, but perhaps less so to the masses. Perhaps it might be worthwhile to choose a design and marketing approach that appeals to the mainstream, so to make this a good option for even more people?
