I got this above email just minutes ago.
We’ve all read Cialdini’s “Influence”, right (if you haven’t yet, do it now). We’ve all been victims of scarcity principle (“only 4 seats left at this price!”) and many of us have used it successfully in our campaigns.
It really does work well – unless the reason for scarcity is blatantly made up! Monthly access to a digital product sold out, yearly access still available? Come on!
What does this do to your credibility? Not much, except people stop believing you. And that’s kind of important.
