Influencer Marketing Case Studies

KOI Footwear wanted to find its next opportunity for growth. The vegan footwear brand had already built momentum through influencer marketing and channels including Facebook and Instagram. One Day Agency was tasked with expanding that success into a new platform, choosing Snapchat for its fit with KOI’s distinctive identity and audience.

The approach was built specifically for Snapchat, adapting the creative and campaign structure to the platform. We began with a month-long test in one UK city, comparing performance against a control city, before expanding nationwide to measure changes in daily sales and revenue.

Once testing demonstrated the channel’s potential, we scaled activity through broad audience targeting and remarketing, refining campaigns as more data became available. During Q3 and Q4 2020, Snapchat contributed more than 25% of the brand’s overall revenue and exceeded its return on advertising spend target by over 40%.

Influencer Marketing for Timberland X Office

One Day Agency supported IPOS, OFFICE and Timberland with influencer marketing amplification for the event OFFICE Presents: Timberland Styled by Emelia Gayner, Worn by You.

The activation invited influencers and selected guests to meet the brand and see the collection styled through Emelia Gayner's creative lens. Influencer marketing creates strong content and cultural relevance, but it only reaches the people in the room unless paid media carries it further, so our job was to extend that moment before, during and after the event. We chose Meta because Facebook and Instagram work particularly well for fashion and footwear, letting event and product creative run across feed, reels and story placements where audiences already engage with lifestyle content. We targeted key London postcodes for the event push.

Running from 24 October to 7 November 2025, the activity delivered 3,465,045 impressions and 3,272 clicks across London, with a 0.09% CTR and a clear delivery peak on 1 and 2 November.
