Surfline is a B2C site for surfing enthusiasts that offers a 15-day free trial to prospects. By splitting its trial conversion process into four steps, the site is able to market to trial prospects who abandon the cart by asking for an email address in the first step.
Here’s the email they sent to those abandoned prospects. We love that it’s simple (especially for a B2C site) but gets the job done by highlighting the benefits of premium membership (i.e., ad-free content).
