The final few emails would then try to sell the book. IMO it's too hard to sell this sort of product to an audience that has never heard of you.
Right now it is just a matter of figuring out where to spend my time.
Shoot for an optin rate ~45.1% at least (if this is hard straight out the box, just have 1 data field, i.e. email address not name+email address)
Profit hack: consider a funnel like this:
squeeze page-->immediate redirect = sales page-->sales page thank you has something like PayWithATweet.com on it...offer a bonus for a social share.
Good luck!
Unfortunately selling with Gumroad I can't track conversions effectively, so that may make page optimization more difficult.
I'll give it a try soon and report back the results (on my blog).
Since the entire purchase happens in a secure iFrame I have no way of knowing on my site when the transaction completes. So I can't use Visual Website Optimizer or Google Analytics to track the conversion.
I hear they are working on this... Otherwise they are wonderful.
Would be happy to share it with you for free in return for an endorsement if you find it helpful.
