I am setting up a Marketo landing page with a form for a contest that is for our existing members. However, if someone comes to this form (i.e. they are emailed the link to the landing page) and they are not an existing member, then I would like this person to register to become a member.
Therefore, If someone fills out the contest form, when they click the submit button, I would like Marketo to confirm that the person is a member (by checking the email address), and if they are, let them know they are entered. If not, I would like them to go to a different page that would tell them that this is only for members but become a member by clicking here (then link to our signup form).
Is this functionality possible?
I would rather do it this way rather than use progressive profiling or the custom HTML form for known users since the functionality used there does not fit our needs.
Any help is greatly appreciated.
