Hand off your ideal customer profile. We deliver a verified email list — by industry, job title, ZIP, real estate segment, or social audience — built specifically for your campaign and verified before it lands in your inbox.
Generic data-broker lists are built for volume, not accuracy. They scrape, refresh slowly, and don't verify before delivery — so half the time, your "5,000 sales managers" turn out to be a mix of HR coordinators, retired contacts, and bounce-back addresses.
That's a budget-burn problem and a domain-reputation problem. Each high-bounce send teaches Google and Microsoft that your sender is shady — which destroys deliverability for every campaign you ever run from that domain afterward.
The fix is a list built to your exact ICP, verified before delivery, and small enough to actually be accurate. That's the service.
Industry, job title, location, revenue band, employee count, technographics — whatever defines your ideal buyer. We build to that spec, not to a generic template.
Every contact runs through SMTP validation, MX check, and catch-all detection before delivery. Target bounce rate after verification: under 3%.
National, state, MSA, or ZIP-level geography. For real estate and home services: homeowners by ZIP with property data. For B2B: company HQ or contact location, your call.
For ICPs easier to find on LinkedIn than in a database — we pull verified business emails for the LinkedIn audiences you target, then verify them.
CSV by default. Google Sheets, direct push to your sender (Instantly, Smartlead, HubSpot, etc.), or custom format on request.
Keith runs every project. No outsourced account managers. If something needs adjusting mid-build, you message Keith and he handles it.
Quick call to nail down exactly who you want to reach. We define industry, title, geography, company size, and any technographic or behavioral filters that matter. Output: a one-page scope doc.
We pull a 25-50 contact preview matching the spec and send it to you. You confirm the data quality and ICP fit before we run the full build. Catches mismatched specs early when they're cheap to fix.
We construct the full list using a combination of EmailClik's enrichment stack, LinkedIn extraction, and partner data sources. Each contact is enriched with the fields you asked for.
Every email runs through the multi-step verification stack. Catch-alls are flagged separately so you can decide whether to include them. Bounces are removed. Delivery target: sub-3% bounce.
Final list delivered in your chosen format with a quality report (verification stats, ICP-match rate, segment breakdown). Standard turnaround: 5-7 business days for lists under 5,000 contacts.
Keith Rainville started in email marketing in the early 2000s — back when "list hygiene" wasn't a buzzword and every campaign you sent taught you something painful about deliverability. He's built and exited multiple companies (Sprint, Evom, Beer Frog, Fat Yankee Jerky), and now runs EmailClik (the 10-tool lead-gen suite), Client System Pro (white-label CRM), and the Unlimited Leads community.
For list-building specifically, that 20-year arc means: we've seen every data source, every verification trick, every reason a "verified" list bounces 30% anyway — and we know which ones actually work in 2026.
Every project is run directly by Keith. No outsourced account team. No "junior data ops associate" spinning up your build. You get a list-building veteran on the project from start to finish.
Two ways. First, we build to your exact ICP — industry, job title, geography, revenue band, technographics, whatever defines your ideal buyer — rather than handing you a generic list. Second, every contact is verified before delivery using a multi-step verification stack (SMTP check, MX validation, catch-all detection). Most broker lists are scraped, stale, and 20-40% bounce on first send. Ours target sub-3% bounce.
Standard turnaround is 5-7 business days for lists up to 5,000 contacts. Larger or more complex builds (multi-segment, custom enrichment) run 10-14 business days. Rush turnaround is available.
CSV by default, with columns for first name, last name, email, company, title, location, plus any custom enrichment fields requested. We can also deliver in Google Sheets format or push directly into your sender of choice (HubSpot, Instantly, Smartlead, etc.) on request.
Primarily B2B. We also build homeowner-by-ZIP lists for real estate, mortgage, and home services verticals, plus social-audience extraction for B2B targets that are easier to find on LinkedIn than in a database. We don't do consumer sweepstakes lists or anything from sketchy data sources.
Email accuracy targets sub-3% bounce after our verification stack. Title and company accuracy are typically 90%+ at delivery. Phone numbers, where included, are 75-85% accurate (industry baseline for B2B mobile direct dials). We document accuracy expectations in the project scope before you commit.
Pricing is scoped per project based on size, complexity, and turnaround. Small focused builds (1,000-2,500 contacts in a defined niche) start in the low four figures. Larger or multi-segment builds scale from there. We don't publish a rate card because every project is different — book a 15-minute call and we'll quote it on the call.
Send us your ICP. We'll build and deliver 100 verified B2B contacts at no cost so you can see the data quality before you commit to a full build. No credit card. No upsell. Just the sample.
