Why list quality decides outreach results
The best copy in the world fails if it lands in the wrong inbox.
Bounced emails hurt your domain, wrong contacts waste your reps’ time, and outdated data makes you look careless. A clean, targeted list fixes all three before you send a single message.
Saves sales time
Reps talk to real decision-makers, not gatekeepers or people who left the company.
Makes personalization possible
Rich data gives you real reasons to reach out, not “Hi {first_name}.”
Outreach is only as good as the list behind it. Bad data doesn’t just fail quietly. It damages your domain and your reputation.
Anatomy of a verified contact record
Every field your team needs to personalize and route.
Here’s what a single record looks like. Fields are customized to your ICP and outreach plan.

Data sources we combine
No single database is complete.
We combine multiple sources, then verify across them, so gaps in one are filled by another.

What we don’t do
Cheap lists are cheap for a reason.
We don’t cut these corners.
Sell recycled lists
Every list is built fresh for your ICP, not a spreadsheet resold to a hundred buyers.
Pad lists to hit a number
500 perfect-fit contacts beat 5,000 random ones. We optimize for fit, not volume.
Include personal emails
Business contacts only, sourced with CAN-SPAM and GDPR requirements in mind.
Resell your list
Your data is yours alone, never sold, shared, or reused for another client.
Fresh, precise, compliant, and 100% yours.
What’s included
ICP to delivery: one team.
Targeting, building, enrichment, verification, delivery, and optional refresh. Six parts. Pick one to see inside.
ICP & Targeting
We define exactly who counts as a fit before any research begins.
What’s inside
ICP and persona workshop
Target account criteria
Title and seniority mapping
Exclusion rules (customers, competitors, do-not-contact)
Who this is for
The right fit if your outreach depends on reaching the right people.
…and your current data isn’t getting you there.
Sales teams running cold email or calling who need fresh, verified contacts every month.
Founders doing their own outreach without the time to research prospects.
Agencies & consultants targeting a specific niche or region.
Marketing teams running ABM that need complete buying committees at target accounts.
How it works
Most lists delivered in 5–10 business days.
You see the quality before you commit to the full build.
Define your ICP
A short call to agree on industries, titles, company size, locations, and exclusions.
Free sample
We build a 25-contact sample so you can check fit and quality before the full build.
Build & verify
The full list runs through our 5-step verification waterfall: automated checks plus human QA.
Deliver & import
Delivered as a clean file or imported straight into your CRM and outreach tools.
Common questions
Asked before every list.
Depends on the number of contacts, how niche your ICP is, and which enrichment fields you need. We share exact pricing on the strategy call after scoping your list.
Every email is validated and every contact passes human QA before delivery. If contacts bounce or turn out to be wrong, we replace them.
Yes. For niche industries or local businesses that big databases miss, we add manual research from websites, directories, and associations.
We can. Many clients pair list building with our cold email, LinkedIn, or multi-channel outreach services. The list also works on its own if your team runs outreach in-house.
We only collect business contact information and build lists with CAN-SPAM and GDPR requirements in mind. We recommend confirming your own outreach practices with legal counsel for regulated regions.
CSV or Google Sheets, or imported directly into HubSpot, Salesforce, Pipedrive, GoHighLevel, or Apollo, segmented by persona, industry, or region, with ready-to-use fields for email and LinkedIn tools.
