I've signed up to check it out. As Alex said, it's a good idea, nice design, etc.

Maybe the feature exists and I didn't spot it, but if you white labelled it so that web designers could send out branded messages to their clients as a value-add, I think you could see paid accounts pick up a bit.

Edit: OK, first email is in. Seems that I have to click a link or get an attachment - this is why I already avoid the Analytics mailed reports. Any chance you can just send the data in the email or does the API not permit it for some reason? I probably wouldn't use this going forward if I had to click through to something or open a PDF, I know that's sulky but just how it is.
