Fun Cases
- The brief

- What we did
- We rebranded the business, starting with the logo, and built a new Shopify theme from scratch with our own personaliser in it. We also run their SEO, paid ads and email marketing, and we built the AI tools and warehouse system they use.
- Results
- Revenue is up 300% over the last five years. Email brings in 30% of revenue, and AI triage has cut customer service hours by 70%.

Background
Fun Cases ship thousands of phone cases a week from a catalogue of over 20,000 designs, and we've run their eCommerce since 2012, before we were called Webgro. The most recent project was a full rebrand and a new Shopify theme built from scratch, including a custom product personaliser that replaced a paid third-party app. Revenue is up 300% over the last five years.
Part 1 of 3
Rebrand & Website
A full rebrand (logo, tone of voice, social, email) and a new Shopify theme built from scratch, with a custom personaliser that replaced a £5,000-a-year app.
The rebrand
A new brand across every channel
Fun Cases had outgrown its old look. We rebuilt the brand starting with the logo: a bold pop-art identity, a new tone of voice, and a design system of rounded blocks, ink outlines and a colour palette chosen to feel fun. Some things stayed the same, including the promise that every order plants a tree.
The website, social templates and a new email marketing system in Klaviyo all launched at the same time, so every channel moved to the new brand together.

The theme
A new theme for a 20,000-product catalogue
We built the new theme from scratch around how people shop for phone cases. It has a mega menu with trending collections and products, predictive search, a native wishlist, and a slide-out cart that shows progress towards free shipping and a free gift.
Every section can be edited in the theme editor and the colour palette is a theme setting, so the in-house team can restyle or rearrange pages without a developer.

Phone model selector
Choose your phone model once
With 20,000 designs, customers shouldn't have to check compatibility on every product. The site asks for their phone model once and remembers it. From then on, every product image in collections, search results and product pages shows the case on that exact phone.
This removes the biggest source of doubt when buying a phone case: whether the design the customer likes will fit the phone they own.
The personaliser
A custom case designer built into the theme
Custom cases are a large part of the business. The previous design tool was a third-party app costing nearly £5,000 a year. We replaced it with our own full-screen editor, built into the theme, where customers add photos, text and stickers to a live mockup of their exact phone and case type.
The editor adds a print-ready file to the order, so the studio prints exactly what the customer approved. There's no monthly fee or third-party checkout script, and Fun Cases own the tool outright.

Marketing & SEO
Paid search, paid social, email and organic search, built on technical SEO that Google and LLMs can read easily.
SEO
Ranked #1 for 'Phone Cases'
We built SEO into the rebuild from the start: content architecture, internal linking, technical foundations, and a content programme tied to the merchandising calendar.
Fun Cases have since reached #1 on Google UK for 'Phone Cases', one of the most competitive category terms in the market.

Email marketing
Over 30% of revenue from email
Email brings in more for its cost than any other channel Fun Cases use. We run lifecycle flows in Klaviyo, design campaigns around the product drop calendar, and segment customers on what they do rather than on vanity fields.
Over 30% of total revenue now comes through email, and that revenue doesn't depend on extra ad spend.

PPC
£35k a month on Google and Meta
We run paid media on Google and Meta, with combined spend of around £35,000 a month and blended ROAS consistently above 8. Search, Shopping, Performance Max and paid social campaigns are all optimised against product margins rather than top-line revenue alone.
We manage the spend week to week as the catalogue grows.
Part 3 of 3
Custom Apps
Three AI tools in daily use, a custom Stock System, and an order-routing app that sends orders to the print floor, all built around how Fun Cases work.
Order routing
Automatic order routing
Fun Cases invested in automatic printing machines, but not every order can go to them. It depends on the phone model and case type the customer chose.
We built a routing app that checks every order as it comes in. Orders the machines can handle go straight to the automatic printers with no manual step, and the rest are queued for manual printing in-house. On the automatic route, an order can be placed and printed within two minutes.

Hi Lola, sorry about that. I’ve generated a pre-paid return label for the iPhone 13 case (check your inbox) and dispatched the iPhone 14 replacement on priority shipping. It should arrive Thursday. Anything else I can sort before your trip?

Stock System
A custom warehouse management system
Off-the-shelf warehouse management software was either too big or too limited for Fun Cases, so we built a custom WMS for their operation. It connects directly to Shopify, shows live stock without any middleware, and the client owns it outright.
The system also includes a productivity tracker for the pick-and-pack team, AI restock and fulfilment recommendations, and a set of smaller tools we build as the ops team ask for them. We keep adding to it.
