Case Study: Sunday boosts connect rates and SDR confidence with Cognism

Cognism’s Accurate Mobiles Increase Connect Rates by 69%

Team Sunday, a Belgium-based sustainable company fashion brand, needed better B2B data to support outbound sales and demand generation across EMEA. Before Cognism, the team was dealing with stale contact lists, inaccurate mobile numbers and email addresses, and limited data coverage/compliance for its core markets, making it harder for SDRs to reach busy decision-makers and scale hiring plans effectively.

Using Cognism’s B2B sales intelligence and data enrichment platform, Team Sunday improved list building, LinkedIn prospecting, CRM mapping, and HubSpot integration. The impact was significant: connect rates increased from 58% to 69%, the team achieved an 85-95% match rate for LinkedIn Matched Audiences, and the Head of Demand Generation said he hit target for seven straight months while SDR confidence rose thanks to fresher, more accurate data.
