Maximizing BetterContact’s Customer Retention by Validating Phone Numbers at Scale
Overview
BetterContact is a B2B contact data provider specializing in data enrichment. They aggregate contact data from leading providers like RocketReach and People Data Labs, then surface the best available contact details for their users. However, phone number quality was a persistent blind spot. By utilizing Real Contact API, BetterContact was able to eliminate between 25-35% of invalid, disconnected, or misattributed phone numbers from their output and reinforce their position as a premium data provider.
The Challenge
BetterContact aggregates data from multiple sources and runs it through validation layers before delivering it to customers. For email, they run SMTP validations to get a clear quality signal. But for phone numbers, that kind of validation simply didn’t exist. It was a black box.
Without reliable phone verification, BetterContact faced some key challenges:
- There was no way to objectively measure the quality of phone data from their upstream providers.
- Bad phone numbers were reaching customers undetected, undermining BetterContact’s premium positioning.
- They couldn’t build real proof of product quality, which limited their ability to improve.
- They asked customers to export dialer reports to assess accuracy, but no one ever did, leaving them with only anecdotal evidence.
BetterContact needed tangible data, something that could definitively say “this number is likely connected and this one isn’t,” so they could optimize their provider waterfall and deliver on their premium promise.
The Solution
BetterContact implemented Real Contact API to verify U.S. phone numbers at scale and in real time before delivering them to customers. Integrating this verification layer into their existing workflow allowed BetterContact to assess contactability and filter out invalid, disconnected, misattributed numbers before they ever reached end users.
The Impact
Implementing Real Contact API delivered immediate, measurable results:
- BetterContact eliminated approximately 25-35% of invalid phone numbers from their data output that were previously reaching customers and creating a poor experience.
- They made the strategic decision to only pass through A-grade phone numbers, rejecting everything else and ensuring the highest data quality for their customers.
- With clear validation signals, they gained transparency into provider quality, enabling smarter decisions about their data sourcing and waterfall logic.
- Improved data quality led to increased customer retention and long-term trust.
By integrating Trestle’s phone verification solution, BetterContact transformed a black box into a competitive advantage, with the ability to validate data at a scale their growth demanded. They can now prove their data quality, optimize their provider relationships, and confidently deliver validated, high-quality data.
