Case Study: Libertarianism.org achieves 125% email list growth with VYPER

How Libertarianism.org Increased Their Email List by 125% From 1 Giveaway

Libertarianism.org, the Cato Institute’s hub for resources on the theory and practice of liberty, faced a weak email acquisition strategy: subscribe links were often overlooked and they avoided pop-ups to keep site quality high. Looking for an easy way to grow subscribers, Libertarianism.org found VYPER and used its giveaway tools to run a focused book giveaway they could set up in under 20 minutes.

Using VYPER’s giveaway platform and countdown timer, Libertarianism.org promoted a book giveaway only through their social channels and existing newsletter, relying on shares and forwards to expand reach. The campaign generated heavy engagement—likes, shares, and signups—and produced a measurable 125% increase in their email list from a single giveaway, demonstrating VYPER’s rapid, high-impact solution.
