48% Boost in New Signups for Audible

When response rates for standard DL and A5 inserts began to plateau, Audible knew it was time to try something new. They turned to Webmart for a solution that would reinvigorate signups and drive engagement.

In just three months, our innovative approach—featuring a die-cut, four-page insert in the shape of an iPhone—delivered incredible results: a 48% boost in signups over the DL version and 26% more than the A5 insert. Audible was delighted with the outcome and is now exploring further improvements to build on this success.

The Challenge

Audible had hit a ceiling with traditional insert formats like DL and A5, which were no longer driving significant signups. The challenge was to create an eye-catching and engaging design that would grab attention, convey their free audiobook offer, and funnel users to their website to sign up.

The Solution

Webmart worked closely with Audible’s creative team right from the conceptual stage, providing technical and production advice to ensure a seamless transition from idea to execution.

Here’s what we delivered

• Innovative Design – A die-cut, four-page insert shaped like an iPhone, made from 250gsm gloss paper.
• Realistic Aesthetic – Designed to mimic the Audible app interface, complete with a popular audiobook “playing” on the screen.
• Clear Call-to-action – Simple and direct instructions guiding readers to the Audible website to claim their free audiobook
• Data-Driven Insights – We implemented a variety of trackable URLs to continuously test and refine creative elements for optimal signup rates.
