The Challenge:
Every campaign launch felt like a probability game with increasingly poor odds. Email deliverability was inconsistent some messages reached intended recipients while most were diverted to spam folders. The issue wasn't messaging quality or value proposition; it was fundamental data quality problems. Their contact database contained unverified email addresses, inactive domains, and outdated contact information. Even supposedly "warm" lists generated bounces and hard delivery failures. Each bounce damaged their sender reputation, creating a downward spiral of decreasing open rates despite efforts to warm domains, switch platforms, and revise email templates.
The Redrob Solution:
Instead of addressing symptoms, Redrob tackled the root cause through their Verified Emails & Phones system. The platform cleaned their entire database using a comprehensive 3-step verification process across 19+ data sources, providing proof of validity rather than assumptions. Invalid addresses were removed, risky domains were flagged, and campaigns finally reached genuine recipients with active email accounts.
Measurable Results:
71% reduction in bounce rates
Deliverability improvement: 82% → 98%
42% increase in inbox placement rates
4.6 ROI from recovered outbound performance
Complete domain reputation recovery within 30 days
Impact:
The data quality transformation restored confidence in their outreach capabilities and rebuilt their sender reputation from "unknown contact" to "trusted source" status. Every email now reaches its intended destination, creating the foundation for meaningful prospect engagement and sustainable outbound success.
