Page Expiration
I'd love to be able to use the 'What's The Date' feature, to determine when a tag was applied to a contact, and then use that as the start date of a 4 day promo offer.
Then this new feature I'm requesting would send them to the offer page if it's still within the 4 days, or if not then send them to an 'offer expired' page.
For extra awesomeness, it would give us the ability to merge the offer end date in the email and on the page, along with a countdown timer for the offer page.
This would pretty much be the best thing ever.
This can be accomplished with Smart Links!
