Phone Numbers

Why This Matters

Phone numbers are a direct and effective way to connect with prospects, making them a critical asset for outreach. Accurate phone numbers ensure your team reaches the right contacts, avoids wasted time, and maintains a professional reputation by reducing failed calls or misdirected attempts.

How We Collect This Data

Warmly sources phone numbers through a network of specialized data vendors, each focusing on different regions of the world. This ensures broad coverage and the ability to deliver accurate contact data regardless of geographic location. To maintain quality, we cross-reference vendor data and validate numbers to confirm accuracy.

How We Track Quality and Quantity

To ensure reliable phone number data:

Customer Feedback: We allow customers to report invalid numbers, marking them in our system to continuously vet and improve vendor data.

Vendor Performance Monitoring: Warmly evaluates vendors regularly, removing underperformers and optimizing the vendor waterfall to maintain high-quality standards.

Data Richness and Enrichment

Warmly enriches phone numbers by adding context, such as the individual’s job title, role, and company information. This ensures the numbers are not just accurate but also actionable, helping your team target the right people effectively. By combining global vendor data with real-time feedback and validation, Warmly delivers high-quality, enriched phone numbers that drive better engagement.
