⚡ The Problem: Why Comment Scrapers Waste Your Time & Budget

When an influencer, founder, or enterprise posts a viral lead magnet on LinkedIn ("Comment 'PLAYBOOK' and I'll send you our 2026 Outbound Playbook"), hundreds or thousands of in-market B2B buyers raise their hand.

Existing tools like harvestapi/linkedin-post-comments or PhantomBuster only scrape raw comment text ("Interested!", "Great post!"). To actually contact these people, growth teams have to:

1. Export comments to a CSV.
2. Manually scrape their LinkedIn profile URLs.
3. Upload to Clay, Apollo, or Dropcontact to enrich work emails (paying $0.40–$0.80 per lead).
4. Spend hours stitching spreadsheets and writing icebreakers.

The Solution: This Actor handles the entire pipeline in 1 automated run for just ~$0.02 per enriched lead.

🚀 The 4-Tier Comment-to-Lead Engine

| Tier | Name | What It Does | Advantage | | :--- : | :--- | :--- | :---: | | Tier 1 | Lead Magnet Trigger Filter | Filters commenters by specific trigger words (e.g. SCALE, PLAYBOOK, SEND, GUIDE) so you only pay for high-intent buyers. | Zero Waste on Spam Comments | | Tier 2 | Intelligent Headline Dissection | Automatically parses complex LinkedIn headlines (e.g. VP of Sales @ Retool | Ex-Google | Angel) into clean jobTitle (VP of Sales) and companyName (Retool). | Structured B2B Lead Profile | | Tier 3 | BounceVerify Email Engine | Resolves corporate domain, analyzes MX records, generates enterprise permutations, and verifies deliverability via zero-send SMTP handshakes (first.last@company.com). | Live SMTP Deliverable Work Email | | Tier 4 | Personalized Outreach Hooks | Auto-crafts customized cold email subject lines and contextual icebreaker hooks referencing the specific post topic and author. | 10x Higher Cold Email Reply Rates |

🛡️ The "No Email, No Pay" Guarantee

We believe you should only pay for verified, actionable data that drives real pipeline.

• No Email Found? You Pay $0.00: If our engine cannot find and verify a deliverable corporate email for a commenter, the email delivery event charge never triggers.
• Deliverability First: Every email goes through syntax verification, corporate MX record validation, enterprise format pattern matching, and real-time SMTP handshakes. Catch-all or undeliverable addresses are protected by our zero-waste billing logic.
• Fair & Transparent: You only ever pay for valid, high-confidence corporate emails delivered straight to your dataset.
