Not all webinar registrants are equal. Clay lets you score every registrant by actual buying signals -- company size, funding recency, ICP match, LinkedIn activity, and job posting patterns -- so your human follow-up focuses on the 20% most likely to convert to qualified meetings. A 500-person webinar list with proper scoring consistently generates more pipeline than the same list followed up uniformly at scale.
Why Do You Need to Score Webinar Registrants Before Human Follow-Up?
73% of B2B marketers say webinars produce the highest-quality leads (ON24, 2026 Webinar Benchmark Report). But a 500-person webinar list still contains enormous signal variation. Some registrants are your exact ICP with active budget and fresh funding. Others are competitors, researchers, or students. Following up every registrant with equal priority wastes your best salespeople on low-fit contacts while delaying outreach to the ones who will actually convert. Clay lets you score the full list in hours by pulling real buying signals for each contact -- so human follow-up goes immediately to the right 20% within 24 hours of the event ending.
How Do You Import and Prepare Your Registrant List in Clay for Scoring?
Export your webinar registrant list from your hosting platform (Zoom, Demio, or Airmeet) as a CSV with name, email, company, and job title. Import into Clay. If registrants signed up via LinkedIn, you will have profile URLs -- these are high-value enrichment anchors that improve match rate significantly. If you only have email and name, Clay can match most contacts to LinkedIn and Apollo records automatically using email-to-profile matching. Before scoring, add a manual column noting whether each contact attended live or only registered. Live attendance is your single highest intent signal and must be added as a manual input from your platform export before any automated enrichment runs.
What Enrichment Columns Should You Build in Clay for Registrant Scoring?
Add these Clay enrichment columns for each registrant:
Company fit signals:
- Company size (Clearbit or Apollo): flag 200-5,000 employees as ideal range
- Industry match: does the company match your ICP industry list?
- Funding recency (Crunchbase via Claygent): raised in last 18 months indicates active budget
- Tech stack (BuiltWith): stack includes technology your product integrates with
Contact fit signals:
- Job title seniority: VP or C-level = 3, Director = 2, Manager or IC = 1
- LinkedIn URL confirmed: yes or no (confidence in contact accuracy)
- LinkedIn activity recency: posted in last 30 days = engaged, active buyer
Intent signals:
- Active job postings for roles your product serves: company is actively investing
- Recent company news mentioning your event topic (Claygent): directly relevant problem confirmed
- Event attendance: attended live or registered only (manual field from your export)
How Do You Build the Clay Scoring Formula and Route by Tier?
In Clay, add a calculated column summing these scores:
- Company size in ICP range: +2
- Industry match: +2
- Funding in last 18 months: +3
- VP or C-level title: +3
- LinkedIn activity in last 30 days: +2
- Attended live (not just registered): +4
- Active job postings in your category: +2
- Recent relevant news mention via Claygent: +3
Scores above 15: hot tier -- immediate personal human follow-up within 24 hours. The outreach should reference a specific event moment: "You attended the CISO panel on AI governance -- here is how three enterprise clients handle the CFO sign-off challenge."
Scores 8-14: warm tier -- personalized automated sequence in Apollo or Outreach with event recording link.
Scores below 8: cold tier -- add to next event invite list only.
Export hot tier to account executives immediately after scoring is complete. Do not batch or delay. The 24-hour window after a live event is when response rates are highest. LinkedOtter by Asaf Katz Advisory uses this scoring structure across all event campaigns. Result: 43 qualified meetings in 60 days from 754 registrants -- a 5.7% conversion rate from registrant to qualified meeting, which exceeds cold outbound industry average by a factor of three. Events start from $6,000. Take the free 60-second check to see how this model fits your pipeline.
