Create HubSpot Contacts from LinkedIn Post Interactions

How It Works

Every time you publish on LinkedIn, people quietly raise their hands by liking or commenting. This workflow turns that engagement into pipeline. A scheduled n8n run calls Phantombuster to pull the latest likers and commenters, enriches each person with a verified email and company data through Dropcontact, keeps Airtable as the source of truth, and finally pushes clean contact records into HubSpot while kicking off a Lemlist cold email sequence and a LinkedIn connection request.

Setup Steps

1. Create Phantoms: In Phantombuster, set up the “LinkedIn Post Likers”, “LinkedIn Post Commenters”, and “LinkedIn Network Booster” phantoms and target the post you want to track.
2. Connect Credentials in n8n: Add Phantombuster, Dropcontact, Lemlist, HubSpot, and Airtable credentials inside n8n.
3. Prepare an Airtable Base: Create a Contacts table with fields for name, email, company, status, and LinkedIn URL.
4. Configure a Lemlist Campaign: Build the cold email sequence in Lemlist and copy its campaign ID into the Lemlist node.
5. Schedule the Cron Node: Choose how often to check for new engagement. The default runs hourly, which fits most posting cadences.
6. Activate the Workflow: Turn the workflow on in n8n so each tick checks for fresh likers and commenters.

Automation Workflow

Cron (hourly) → Phantombuster Launch (Post Likers + Post Commenters)
    ↓
Phantombuster Get Output → Dropcontact Enrichment
    ↓
Airtable List → IF (contact already in Airtable?)
    ↓
Set Fields → Airtable Update  OR  Airtable Append
    ↓
Lemlist Add to Campaign → Phantombuster Launch (Network Booster)
    ↓
HubSpot Create or Update Contact

Benefits

• Zero manual exports: Likers and commenters flow straight into HubSpot without CSV handoffs or copy-paste.
• Enriched contact records: Dropcontact appends a verified email, job title, gender, and legal company information before HubSpot sees the record.
• Multi-touch outreach: Lemlist delivers a personalized cold email sequence while the LinkedIn Network Booster sends a connection request from your profile.
• Deduped against Airtable: Existing contacts are updated in place and only new engagers are appended, which keeps HubSpot clean.

Advanced Features

• Multi-phantom orchestration across Post Likers, Post Commenters, and Network Booster
• Conditional routing that updates existing Airtable records or appends new ones based on the IF node
• Chained enrichment and outreach across Phantombuster, Dropcontact, and Lemlist in a single scenario
• Hourly Cron trigger with phantom scheduling that respects LinkedIn rate limits
• Dual-destination writes with Airtable as the source of truth and HubSpot as the CRM of record

Use Cases

• B2B founders turning LinkedIn thought-leadership posts into qualified pipeline
• Sales teams warming up engagers before SDR outreach
• Agencies running LinkedIn-first lead generation on behalf of clients
• RevOps teams keeping HubSpot in sync with social-channel engagement
• Solo operators who want to stop manually screenshotting post reactions after every launch

Pro tip: You can now get similar results directly with the Phantombuster HubSpot integration. It will however, consume a Phantom slot and might require you to upgrade to a higher plan
