I couple months ago I created a launch page for my SAAS product using an Aweber form to collect emails during beta testing because I like their features. This worked fine before my application was actually complete and it served the purpose of allowing me to collect emails.
Now that my app is created, what can I do to convert those on the email list into users in my application or should I send out an email asking those people to create user accounts?
Should I scrap Aweber and just send out my own newsletters programatically. I would love to hear how others have handled this issue.
