Email to LinkedIn: Reverse Lookup Your Entire Contact List in Minutes

⏱️ 10-min setup | 🔧 n8n + FullEnrich

Want this workflow running in your company without touching n8n?

I’ll set it up for you in 48h. Drop your email list → get full LinkedIn profiles back.

Book a call.

---

You have a list of emails. You need LinkedIn profiles, job titles, company info.

Manual research: 2 min per contact. 500 contacts = 16 hours of copy-paste hell.

This workflow: Drop your list → Get enriched data back in minutes.

---

---

What You Need

Apps:

• n8n (self-hosted or cloud)

• FullEnrich account (reverse email API)

• Google Sheets (or other)

---

How to Build It

1. Set Up Your Google Sheet

Create a sheet with your email list:

email sarah@techflow.io

john@acme.com

lisa@startup.co

Column name must be email, Email, or EMAIL. That’s it.

---

2. Create the n8n Workflow

You’ll build 2 flows:

• Flow 1: Send emails to FullEnrich

• Flow 2: Receive enriched data back via webhook

---

3. Flow 1: Send Emails to FullEnrich

Node 1 — Manual Trigger

Start with a manual trigger (or schedule it).

---

Node 2 — Google Sheets (Read)

• Operation: Read rows

• Document: Select your spreadsheet

• Sheet: Select your sheet

---

Node 3 — Code (Format Data)

javascript

// Transform Google Sheets data into Fullenrich format
const items = $input.all();

// Extract emails from the sheet
const emailData = items.map(item => ({
  email: item.json.email || item.json.Email || item.json.EMAIL
})).filter(item => item.email);

// Create the request body
const requestBody = {
  name: `Enrichment_${new Date().toISOString().split('T')[0]}`,
  data: emailData,
  webhook_url: "YOUR_WEBHOOK_URL_HERE"
};

return [{ json: requestBody }];

⚠️ Replace YOUR_WEBHOOK_URL_HERE with your actual n8n webhook URL (from step 4).

9:30 AM

Node 4 — HTTP Request (FullEnrich API)

• Method: POST

• URL: https://app.fullenrich.com/api/v2/contact/reverse/email/bulk

• Authentication: Header Auth

• Header Name: Authorization

• Header Value: Bearer YOUR_FULLENRICH_API_KEY

• Body Type: JSON

• Body: ={{ $json }}

---

4. Flow 2: Receive Enriched Data

Node 1 — Webhook

• HTTP Method: POST

• Path: fullenrich-webhook

Copy the webhook URL — paste it in the Code node above.

---

Node 2 — Google Sheets (Append)

• Operation: Append

• Document: Select your results spreadsheet

• Sheet: Select your sheet

• Map the fields: linkedin_url, first_name, last_name, job_title, company, etc.

---

What You Get Back

For each email, FullEnrich returns:

• LinkedIn URL

• First name / Last name

• Job title

• Company name

• Company LinkedIn

• Location

• Industry

From sarah@techflow.io → Full profile ready for outreach.

---

Make It Yours

Automate the trigger:

• Replace Manual Trigger with Schedule (daily/weekly)

• Or trigger when new rows are added to the sheet

Chain with outreach:

• Feed enriched data into Lemlist/Instantly

• Auto-add to HubSpot/Pipedrive

• Send to Slack for sales team review

Add filtering:

• Only enrich emails from specific domains

• Skip already-enriched contacts

• Filter by company size or industry after enrichment

Error handling:

• Add IF node to catch failed lookups

• Log errors to separate sheet

• Retry failed emails

---

Why This Works

1. Scale. Enrich 500 contacts while you grab coffee

2. Data quality. FullEnrich aggregates 15+ data sources

3. Cost efficient. Bulk API = cheaper than manual lookups

4. CRM ready. Output goes straight to your sheet/CRM

---

🎯 Don’t want to build this yourself?

I install this workflow in your stack. You drop emails — enriched profiles appear automatically.

Let’s talk

---

That’s it. You just turned a list of emails into actionable sales intel.
