I'm curious to see if a lead can be entered into a sweepstakes only after completing some requirement, i.e. after sharing on social? I see that bonus entries can be given for these sort of activities, but i don't see anything like this for entry. Has anyone done anything like this before?
Jeremy,
It might be possible to trigger based on Social Sharing or to ask them to fill out a form. I haven't tried to do this before, however.
Perhaps to let them enter and then wait 1 day, check if they completed requirement, then send confirmation email.
