It would be INCREDIBLE if people who have already opted-in for one of our squeeze pages can be shown a different thank you page (or a different funnel entirely) if that same email is already in our contacts and/or that email has already been submitted for that exact page or funnel. For example, let's say I have a webinar I'm promoting and I want to have real scarcity for anyone who registers... well what I've found is that a lot of times I get the same people that have registered before to register again for that same event. I understand that I can simply change my workflow settings to only allow runs ONCE but it would be way better if they could get a custom experience all together. (Otherwise they'll end up on the same thank you page promising that experience and the follow ups emails or next pages don't come.) So for instance, if someone tries to opt-in again to something I don't want them to, then it'll show them a custom thank you page saying that the special presentation and offer have already expired...and from there I can then lead them elsewhere. (Whether it be a button that leads to a specific webpage, or an entirely differently funnel with some other special offer with upsells, downsells, etc.) This is important because I want my scarcity to mean something and be real, and if tons of my customers and leads know they can just optin again later, they won't have a real sense of urgency to ACT NOW!
