Background

Earmax Media is a media agency specializing in podcast advertising working across the UK and Australia. The team combines curated podcast media planning with tailored audio creative to help brands reach the right audiences in the right listening environments.

Challenges

Before Magellan AI, Earmax Media had to pull campaign data from whichever tracking provider each network used, then reconcile those reports manually. For campaigns spanning many shows and publishers, that process slowed reporting and created inconsistent views of performance.

Earmax Media’s strategy combines precise show selection with creative tailored to each audience. To prove that approach and grow client investment, the team needed attribution that connected podcast exposure to visits, leads, and purchases.

Results

  • Magellan AI gave Earmax Media a single view across 21+ placements, replacing manual reconciliation across multiple tracking providers.
  • Visitor conversion rates grew more than 12x over two years, from under 0.5% to over 6% across curated showlists and host-endorsed sponsorships.
  • The 2025/26 campaign tracked 328 purchases of travel packages priced between £2,000 and £5,000, with client investment growing 4x since the first campaign.
  • The campaign won Best Use of Audio in Media Planning at the Campaign Audio Awards, recognized for proving True Crime podcasts high-performing and brand-safe for luxury travel.
