Login and register option for Hosted Pages

Login and register option for Hosted Pages

Hello,

I like to provide existing customers with a new subscription offering. Typically what a Hosted page is for. However, when on the Hosted Page, the user should login and register instead of him creating another profile with a potentially duplicate email address.

Is this possible, i.e. using a magic URL when displaying the Hosted Page??
Other options to avoid duplicate customer records?



Thank you,
Ulf
