Case study: Coldstream Filters

6 June 2023
Studioworx Case Study

Our sister company Studioworx, a web development and marketing agency, provided a marketing strategy for their client Coldstream Filters to target new potential customers. Read the case study about how Studioworx successfully increased traffic to their website.

The client

Designed, engineered and manufactured in Norfolk, Coldstream ceramic water filters provide clean, great-tasting, affordable drinking water on tap. 

Coldstream is popular in parts of the world where tap water is not safe to drink. As more of us in the UK begin to ask what’s in our water, Coldstream is fast emerging as the brand for health-conscious consumers looking for affordable, environmentally responsible alternatives to bottled water.

The challenge 

Launching Coldstream as a direct-to-consumer brand meant educating the UK public about a highly effective, affordable and environmentally-friendly solution. But first, we had to introduce the problem. Filtered tap water is not yet mainstream in the UK because unlike many other countries where Coldstream ceramic filters are popular, the tap water is considered safe to drink. And unlike the more common jug filter, Coldstream’s ceramic filters are usually installed out of sight under the kitchen counter, meaning our audience was unlikely to have seen photos of them on social media.  

The solution  

Studioworx designed a values driven multi-channel marketing strategy targeting potential customers at every stage in the journey, from discovery to consideration, purchase and repeat purchase.  

The process 

Our specialist ecommerce user experience designers and developers updated Coldstream’s existing B2B website to give it a more direct-to-consumer look and feel.  

We created an educational (and delightful) animated video series which highlights the most important benefits of Coldstream filters. Using paid social media campaigns, we targeted distinct audiences with content tailored to their particular interests and values, from saving money to improving health and minimising environmental impact. 

We grew the email list and set up automated email campaigns re-target previous website visitors with content that directly addressed their concerns, whether they needed help choosing the right filter, the reassurance of Coldstream’s high seller rating on Trustpilot, or a reminder about an item left in their shopping cart. An automated refill reminder kept customers engaged, driving up customer lifetime value. 

To capture high-intent search traffic, we set up Google Ads campaigns, ensuring that Coldstream filters were always there when customers searched for them in Google Search and Shopping results.

The results 

Significant increases in high quality traffic from a range of sources paired with a smoother user journey resulted in a significantly higher conversion rate and a threefold increase in GMV sales within 8 months. Brand awareness continues to increase, with over 13 million new users reached in the UK via social media alone.
