The SDR playbook for turning a LinkedIn or Sales Navigator search into a cold-email-ready lead list with verified email addresses — in under 30 minutes.
Quick answer
To build a cold email lead list from LinkedIn: (1) define your ICP with Sales Navigator boolean filters (title + industry + headcount + geography), (2) scrape the search results with a Chrome extension, (3) enrich each profile with verified work email addresses via multi-provider waterfall + SMTP verification, (4) filter out catch-all domains and role-based addresses (info@, sales@), (5) export the clean list to CSV and upload to your cold email tool (Instantly, Smartlead, Lemlist). Typical result: 500 verified, cold-email-ready contacts in 15-20 minutes. Bounce rate under 5%.
Step by step
6 steps — about 10-15 minutes end-to-end.
Use Sales Navigator's Lead Search with boolean filters. Target by: job title ("VP Sales" OR "Head of Growth"), company headcount (50-500), industry (SaaS, B2B), geography (US, UK). Save the search for recurring use. If you don't have Sales Navigator, regular LinkedIn search works for smaller ICPs.
Open the search in your browser. Click the Chrome extension. The tool paginates through all results (up to 2,500 per search, or more with the bypass), extracts profile data (name, title, company, LinkedIn URL), and prepares for enrichment.
The extension runs a multi-provider email waterfall on each scraped profile: generates pattern candidates (first.last@company.com), queries 5+ data providers, runs real-time SMTP verification. Only confirmed-deliverable addresses are marked "verified". Typical hit rate: 65-85%.
Filter out: (1) catch-all domains (email accepted but may not deliver — flag as "risky"), (2) role-based addresses (info@, sales@, support@ — will get you spam-flagged), (3) personal email addresses (gmail, yahoo — only email work addresses). Target: 100% work emails, zero role-based, under 10% catch-all.
Before uploading to your cold email tool, cross-check by email against your CRM and prior campaign lists. Don't re-email people who already replied, opted out, or are active customers. Dedupe by email address, not name.
Export the clean CSV. Upload to Instantly, Smartlead, Lemlist, or your tool of choice. Map fields: email → Email, first_name → First Name, company → Company, linkedin_url → Custom Field. Set lead source = "LinkedIn scrape" for attribution. Launch your sequence.
Pro tips
500 leads per campaign is the sweet spot. Enough volume for statistical significance on reply rates, not so much that you can't personalize. 3 campaigns × 500 = 1,500 leads/month is typical for a solo SDR.
Warm up your sending domain first. Never cold-email from your primary domain. Buy a secondary domain (e.g. get-scrupp.com), set up SPF/DKIM/DMARC, warm up for 2 weeks at 20 emails/day, then ramp to 100-150/day per mailbox.
Email quality > email quantity. 300 verified grade-A emails outperform 1,000 unverified emails every time. 3% bounce rate vs 30% bounce rate is the difference between inbox delivery and spam folder.
FAQ
A single Sales Navigator search returns up to 2,500 results (more with the bypass). With 65-85% email hit rate, that's 1,600-2,100 verified email addresses per search. Most SDRs run 2-4 searches per month = 3,000-8,000 cold-email-ready leads.
Under 3% for a healthy sending reputation. 3-5% is tolerable. Above 5% and Gmail/Outlook start throttling or blocking your domain. Real-time email verification keeps you under 3% consistently.
No, but it helps. Sales Navigator gives advanced filters (headcount, seniority, function) and shows up to 2,500 results per search. Free LinkedIn caps at ~1,000 results and has fewer filters. For serious cold email at scale, Sales Navigator is worth the $99/month.
Four things: (1) verify every email before sending (under 3% bounce), (2) warm up your sending domain for 2+ weeks, (3) limit to 100-150 sends per mailbox per day, (4) write 3-line plain-text emails without images, tracking pixels, or HTML formatting.
Yes. Save your Sales Navigator search, set up a weekly scrape schedule, and use the webhook to auto-push new leads into your cold email tool. Each week, only net-new profiles (not in prior exports) flow into your campaign.
In the US: yes, under CAN-SPAM (must include opt-out, physical address). In the EU: permitted under GDPR "legitimate interest" for B2B, but you must honor opt-out requests and only email professional addresses. Always check local regulations.
Well-targeted cold email with verified data: 3-8% reply rate. Poorly targeted or unverified: under 1%. The difference is almost entirely data quality (right person, right company, valid email) + relevance of your value proposition.
Bought lead lists are static snapshots — 20-40% stale within 6 months. LinkedIn scraping + real-time verification gives you fresh, confirmed-deliverable contacts at the moment you build the list. Result: 5x lower bounce rate, 2-3x higher reply rate.
