What This Workflow Does

Manual lead research is one of the biggest time-wasters in sales and marketing. Teams spend hours searching for email addresses, verifying contact information, and manually transferring data between spreadsheets and outreach tools. This workflow eliminates that manual process by creating a fully automated pipeline that transforms raw contact lists into enriched, verified leads ready for personalized outreach.

The automation pulls contact information from Google Sheets, uses Dropcontact to find and verify professional email addresses, enriches each contact with additional professional data, and then automatically adds qualified leads to your Lemlist campaigns. What used to take hours of manual research now happens automatically in minutes, ensuring your sales team always works with accurate, up-to-date contact information.

How It Works

Step 1: Read Contacts from Google Sheets

The workflow begins by reading your contact list from a specified Google Sheet. It processes each row containing basic information like names, companies, and job titles. The automation can be scheduled to run daily, weekly, or triggered whenever new contacts are added to your spreadsheet.

Step 2: Enrich Data with Dropcontact

Each contact is sent to Dropcontact's API, which performs several critical functions: it verifies email deliverability, finds professional email addresses when only basic information is provided, and enriches the contact with additional professional data like LinkedIn profiles, company information, and social media links.

Step 3: Filter and Qualify Leads

Based on the enrichment results, the workflow can filter contacts by specific criteria. You might exclude contacts with invalid emails, prioritize leads from target companies, or segment contacts by job title. This ensures only qualified, relevant leads proceed to the next stage.

Step 4: Add to Lemlist Campaigns

Finally, enriched and verified contacts are automatically added to your designated Lemlist campaigns. The workflow passes all the enriched data, allowing for highly personalized email sequences from day one. You can configure different campaigns based on lead quality, industry, or other segmentation criteria.

Who This Is For

This workflow is ideal for B2B sales teams, marketing agencies, SaaS companies, and any business conducting outbound lead generation. It's particularly valuable for teams that:

  • Maintain lead lists in Google Sheets or CSV files
  • Struggle with email bounce rates and invalid contact data
  • Spend excessive time manually researching contact information
  • Want to scale their outbound efforts without increasing manual work
  • Need to ensure GDPR compliance in their data enrichment processes

  3. Dropcontact account with API access for email verification and enrichment

Frequently Asked Questions

Common questions about lead enrichment automation and integration

Lead enrichment is the process of adding verified data to your contact lists, such as email addresses, job titles, company information, and social profiles. It's crucial for sales because it increases email deliverability, improves personalization, and helps sales teams prioritize high-value leads.
