I just signed up and confirmed my email. Ok... what's next? What's the deal with money that other people are writing about here?
At a minimum I recommend an email that goes out immediately after a person confirms their email. This thank you email should again briefly explain how your product works because if you explained this somewhere on your site then I missed it and I won't be the only one.
Also, consider sending that day's email to the customer right away so they get some immediate value from your service (even if that email had already gone out that day). As it stands I will likely forget about your service tomorrow and then wonder how you got my email address!
Best of luck, I'd like to receive an email when you have that up there. You also might start to get decent search traffic with all that content available to crawlers.
