Automating Lead Enrichment & Campaign Setup with n8n, Dropcontact & Lemlist

What This Automation Does

This workflow reads lead data from Google Sheets, cleans and verifies emails using Dropcontact, and adds leads to Lemlist campaigns automatically.

It solves the problem of manual copy-pasting, errors, and missing contact info.

The final result is accurate leads ready for email outreach without extra manual work.

Inputs and Processing Steps

Inputs: Lead information such as emails, names, company names, LinkedIn profiles, and websites stored in a Google Sheet.

Processing: The workflow pulls rows from Google Sheets. Then, it sends each lead’s email and details to Dropcontact for cleaning, enrichment, and deduplication.

Dropcontact returns verified emails and company info.

Output: Enriched leads are added one by one into a specific Lemlist campaign with personalized fields.

Users wanting better email accuracy and campaign delivery will benefit from this workflow.
