The Challenge

What Carphone Warehouse Needed

As the UK's largest independent mobile retailer with multiple sub-brands, Carphone Warehouse needed creative that performed across every channel while maintaining brand consistency and driving measurable results.

Multiple Sub-Brands

Each sub-brand had its own identity, audience, and tone of voice. Creative had to feel distinct for each brand while remaining part of the wider Carphone Warehouse family.

Underperforming CTR

Existing creative wasn't cutting through. Click-through rates across display, social, and affiliate channels were below industry benchmarks and needed a step change.

No Testing Framework

Creative decisions were based on opinion, not data. There was no structured approach to testing what worked across different audiences, formats, and channels.

Volume at Speed

Campaigns launched frequently with tight deadlines. The creative pipeline needed to produce high volumes of assets across multiple formats without sacrificing quality.

Our Approach

What We Delivered

We became the creative engine for Carphone Warehouse's sub-brands, producing, testing, and optimising campaigns that drove a 42% increase in click-through rates across channels.

1
Sub-Brand Creative Systems

Developed bespoke creative systems for each of Carphone Warehouse's sub-brands, with distinct visual identities, messaging frameworks, and design templates that maintained consistency while allowing each brand to stand on its own.

2
Multi-Format Campaign Production

Produced hundreds of creative assets across display ads, social media, email campaigns, landing pages, and affiliate banners. Every format optimised for its channel, every asset on-brand and on-deadline.

3
Structured A/B Testing

Implemented a rigorous testing framework across all creative. Headlines, imagery, CTAs, colour schemes, and layouts were systematically tested and measured. Winners were scaled, losers were killed. Every decision backed by data.

4
Performance Optimisation

Continuous creative optimisation based on live performance data. Underperforming assets were replaced within hours, winning approaches were adapted across sub-brands, and the CTR climbed steadily to 42% above the starting baseline.

The Results

Measurable Impact at Scale

Data-driven creative that proved its value in the numbers. Every metric moved in the right direction across every sub-brand.

“Dynamics became our go-to creative team across all our sub-brands. They brought a testing discipline we didn't have before, and the results were undeniable. A 42% CTR increase doesn't happen by accident. It happens when every creative decision is backed by data and the team has the talent to execute at speed.”
