Using lightboxes strategically for email acquisition is a website optimization best practice at Monetate. The operative word here is strategic. Since lightboxes are meant to be interruptive, you want to be judicious in your use of them so they enhance the customer experience.

Figuring that people who showed an interest in its sale merchandise would want to be kept up to date on new promotions, the retailer served visitors to the sale page a lightbox that encouraged them to sign up for email alerts. The promotion copy played to this theory by reminding visitors that reduced-price merchandise can sell quickly—suggesting that email subscribers have an advantage in snapping up good deals first.

To ensure the lightbox didn’t slow down the shopping process for those visitors not interested in signing up, the link to bypass the window was placed next to the “submit” button for a quick yes/no decision. The test also restricted the lightbox to display only once per visitor.

How did consumers respond to this in-the-moment approach? The retailer saw a nice 14% improvement to its email conversion rate.
