Pretty cool concept. Get about a 15% CTR with opt-in lists using bit.ly. Maybe because the link is too short to hover your mouse over with these ultra large pixelated monitors? Let's try A/B testing with a MEGAURL and see if that CTR can't go higher!
Too bad there's no back end to track CTR. Would need an API to create a Mega URL for each hashed email or setup a redirect... more work. :disappointed:
