Client: Delta Fiber
Industry: Telecom
Company size: Over 1,000 employees in the Netherlands
Solution: First-party data activation

The challenge
Delta Fiber, a leading telecom provider in the Netherlands, aimed to boost customer acquisition while preparing for a cookieless future. To achieve this, they needed a privacy-safe solution to activate their rich CRM data across digital channels—enabling smarter targeting, increased efficiency, and reduced waste in media spend. Traditional third-party strategies no longer offered the precision or compliance needed to scale sustainably.

The solution
Delta Fiber teamed up with digitalAudience to activate its first-party customer data in a secure and privacy-compliant way. Using the digitalAudience platform, Delta Fiber was able to:

• Create lookalike audiences for targeted prospecting
• Retarget high-intent users across digital platforms
• Exclude existing customers from specific campaigns
• Seamlessly share audiences with partners like Google, Meta, and Adform

This streamlined approach delivered stronger match rates and significantly improved campaign performance.

The results
The collaboration drove measurable improvements across multiple platforms:

• 68 % increase in match rates on Meta
• 40 % increase in Google Customer Match
• 35 % uplift in match rates with publishers
• 16 % increase in match rates on Adform

What they say
“digitalAudience has provided Delta Fiber with a much-needed alternative to third-party cookie-based targeting that has delivered increased match rates across display and social channels. We are now better able to reach our target audiences with relevant messages and as a result we have seen an increase in new customer adoption.”
