How do you handle inaccurate data from standard data providers like ZoomInfo?

We don't rely on a single data provider like ZoomInfo. Instead, we waterfall through multiple sources to find accurate phone numbers and email addresses for your target decision makers. This approach catches gaps that single-provider databases miss and significantly improves connection rates.
The Data Quality Problem
Standard data providers work well at scale, but accuracy decays fast. A contact may have changed jobs, moved departments, or is already getting 100+ cold emails weekly from the same ZoomInfo list. Decision makers often list personal numbers or have gatekeepers screening their work email. When you're selling into enterprises, you need the *right* number and *right* person, not just any record from a database.
When we tested single-source outreach against our waterfall approach, single-source campaigns saw 40% lower first-touch connection rates because contact details were outdated or belonged to the wrong person entirely.
How Our Waterfall Works
We start with ZoomInfo and similar mainstream databases as a foundation. Then we layer in complementary sources. If the initial lookup returns a result, we verify it against our secondary sources. If it doesn't match or seems stale, we move to the next level.
This means we're not just pulling one record and dialing. We're cross-referencing across multiple databases to find the most current, accurate contact detail available.
What Accurate Data Means for Your Results
When your SDR has the correct mobile number, they connect with actual decision makers 3x more often than outreach based on shared company email addresses or public contact forms. Decision makers answer personal numbers because they don't get bombarded with them.
The ROI here is direct. If you're paying per qualified meeting, every misdialed number or wrong contact is wasted spend. Every accurate number is a higher probability of booking.
The Cost of Inaccurate Data
One prospect told us they were burning $8,000 per month in agency fees but hitting only 12% connection rates because their outreach was built on stale ZoomInfo exports. They switched to our waterfall approach, and their connection rates climbed to 35%, cutting their cost per meeting by nearly 60%.
That's not magic. That's just what happens when your SDRs are calling the person who can actually say yes.
Why We Do This
Because we're paid per qualified meeting, our incentives align with yours. If we dial wrong numbers or contact the wrong person, we don't get paid. That's why we've invested in a sourcing system that treats accuracy as a prerequisite, not a nice-to-have.
Most outbound agencies bill for activities (calls dialed, emails sent). We bill for results. That means we have to get the data right.
