I Will Build Targeted B2B Lead Lists With Verified Emails

If your pipeline is running dry or your outreach is hitting dead ends, the problem usually isn't your pitch — it's the list. Inaccurate contacts, unverified emails, and poorly targeted prospects waste time and budget before a single message is sent.

We are Zinn Digital, a specialist list-building team based in London, England, with over seven years of experience delivering high-quality prospect lists to clients worldwide. We combine premium data sources — including LinkedIn Sales Navigator, ZoomInfo, Crunchbase Pro, and Google advanced search — with rigorous two-step email verification to produce lead lists that are accurate, compliant, and immediately actionable.

Every list we build is tailored to your exact targeting criteria: industry, location, company size (by headcount or revenue), and job title. Whether you need C-suite executives, department heads, founders, or any other specific decision-maker, we will source and verify them to your specification.

Each lead record is delivered with:
• First and last name
• Job title
• Verified business email address
• LinkedIn profile URL
• Company name and website
• Business address
• Company phone number

Emails are verified in two stages: first through ZeroBounce to remove invalid and fake addresses, then through a paid SMTP server to confirm deliverability and eliminate spam traps. Every list is also fully formatted and cleaned before delivery.

All data is collected and processed in compliance with GDPR. Under GDPR, businesses may collect and use business contact data, including email addresses, for marketing purposes where a legitimate interest can be demonstrated — which is standard practice in B2B outreach.

Delivery is in your choice of Excel, CSV, or Google Sheets — whichever suits your CRM or campaign tool.

This service is ideal for sales teams, marketing managers, recruiters, founders, and agencies who need a reliable, ready-to-use prospect database without spending days on manual research.
