I have a question regarding lead ids. Currently, we generate a custom id for anonymous users, through our social widgets or through our admin UI. We just implemented Marketo, and while Segment allows us to track Admin UI activity once they submit their email address, there is a possibility that users won't submit a form for a while, and we will lose interesting user data.
Has anyone encountered this challenge? If so, is there a way to better map custom ids to lead ids, or force a custom id to anonymous users?
