I don't know if this means it's time for more competing space in offline mailclients because we're seeing a shift to the in-browser emailclients.
Accompanied with that shift moving to HTML5 & CSS3 compliant browsers is priority #1, as always.
Testing on lotusapp.com only gets you so far.
Obviously it depends a lot on your audience, but I would argue technically minded folk are smart enough to be jaded by fantastically designed marketing spam, and non-tech folk may like the pretty pictures but also would take a text-only email to be more credible/personal in that it looks as if someone actually wrote it to you!
This is from a pure marketing perspective though, anyone have any numbers for either side?
