We tried this with the web app launcher at https://starthq.com https://starthq.com. Visitors could create their app launcher before signing up. It did not work as expected as users were confused and few completed the process. Right now we ask for the email up front, but don't demand that the email is verified by clicking the link we send them. This works much better and we're seeing more than two thirds of the users coming back after the initial visit.
