Do clients provide their own contact lists or does your team source them?

About 80% of the time, your team brings the list. The other 20%, you ask us to source it, and we pass the cost through to you. Either way works, and we've built our process to handle both scenarios without friction.
You Bring the List (Most Common)
When you supply the contacts, you're giving us a head start. We take what you have—whether it's 50 names or 50,000—and immediately start the data validation process. This is actually the smoother path for most clients because you know your ICP better than anyone. You've already done the hard work of identifying who you want to reach.
The catch: about 50% of lists clients provide have complete mobile numbers. That might sound surprising, but it's consistent across industries. Most CRM exports and lists pulled from traditional B2B databases prioritize work email and company phone lines, not direct cell numbers. Since our outreach strategy relies on SMS and direct calling alongside email, gaps in mobile data become a real bottleneck.
When We Source the List
If you don't have a list ready—maybe you're entering a new vertical, or you're growing faster than your research team—you can ask us to source it for you. We pull from multiple data providers, apply your ICP filters, and validate for accuracy before it reaches our SDR team. You cover the cost of the list acquisition, which typically runs $0.15 to $0.40 per contact depending on the data sources and enrichment depth you need.
Most clients who go this route find it worth the investment because we handle the entire sourcing workflow. You don't have to juggle multiple vendor contracts or dedicate internal resources to vetting data quality.
The Real Work: Data Cleanup and Enrichment
Here's what actually takes time: our data team rebuilds most lists from the ground up. When we receive your contacts, we're not just uploading them to our dialer and hitting send. We're cross-referencing names and companies, validating email addresses, verifying phone numbers are still current, and enriching missing mobile numbers through secondary sources.
A list with 500 contacts might have 150 missing mobile numbers. Our enrichment process recovers about 60-70% of those. The ones we can't recover either get marked for voice-only outreach or, if mobile is critical to your strategy, we might flag them for removal.
This isn't a quick process. A team of one working full-time might handle 800 to 1,200 contacts per week through the complete validation, enrichment, and deduplication pipeline. For larger lists—5,000+ contacts—we factor in extra time or bring on additional data resources.
Timeline Impact
If you're supplying the list, build in 1-2 weeks for our team to prep it before your first outreach touches. If we're sourcing, add another 1-2 weeks for acquisition and validation. This isn't friction—it's the difference between a list that converts and one that wastes dialer time on bad numbers.
The investment in data quality compounds. A clean list with verified mobile numbers and current contact info drives 2-3x higher response rates than raw, unvalidated data. Every hour our SDRs spend on bad contacts is an hour they're not reaching decision makers.
What This Means for Your Campaign
Whether you bring the list or we source it, expect our data team to treat it like a refinement project. We'll flag data quality issues before launch, show you what we're enriching, and give you visibility into why certain contacts drop from the active set.
