getmetricmail.com creates simple Google Analytics reports and sends them to you as a PDF.
Currently 3000 free users. A handfull pays, so it makes about $100 per month. A good example of Freemium gone wrong.
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.
We thought about putting the data directly into an email, but the crappy HTML/CSS support in the gazillion email clients, make this a pretty tough job.
Can appreciate the frustration with HTML/CSS support - maybe if you kept your layout really simple and/or called it an Old School theme. Mostly I'd be looking for anything that quickly showed me if there was something wrong with a site (or right, e.g., major incoming link).
Wonder if you can throw in some marketing factoids like "Fourth straight month with an increase in traffic" or "Traffic growth continues; fourth straight month" - the sorts of things a marketing guy can repeat to the boss without any more time or research.
The case here shows what happens when you offer too much features/resouces in the free plan.
The toughest part now is deciding if it makes sense to invest more time into it. But I guess that is a general problem for startups that haven't yet found product/market fit. You can't really know if you are miles or just an inch away from that fit.
As I said we currently have over 3000 users, so there seems to be some interest in such a solution :)
