How to Enrich Leads from a CSV File (Step-by-Step)

Why CSV Enrichment Matters

CSV files are the universal format for lead data. Whether you export from LinkedIn, download from a trade show scanner, purchase a list, or export from your CRM, the data arrives as a CSV. Enriching these files before importing them into your sales tools ensures you start with clean, complete data.

Raw CSV files typically have 40-60% data completeness. After enrichment, you can achieve 80-95% completeness with validated emails, filled-in company data, and AI-generated insights. This enriched data directly translates to better outreach results.

Step 1: Prepare Your CSV

Before importing, clean your CSV: remove duplicate rows, fix obvious formatting issues (extra spaces, inconsistent casing), and ensure column headers are clear. At minimum, include name (first and last) and either email or company/domain.

Standard CSV columns for enrichment: first_name, last_name, email, company, domain, job_title, phone, linkedin_url. You don't need all columns - enrichment will fill in what's missing.

Step 2: Import and Map Columns

Import your CSV into Enrichabl. The platform auto-detects common column names and maps them to the correct fields. Review the mapping to ensure accuracy, especially if your CSV uses non-standard headers.

For large files (10,000+ rows), processing happens in batches. Enrichabl handles this automatically - just import the full file and let the system process it in the background.

Step 3: Validate and Enrich

Run email validation first to identify deliverable, risky, and invalid addresses. Enrichabl's waterfall validation checks multiple providers for maximum accuracy.

Next, add AI enrichment columns. Create columns for the specific data points you need: company size, industry, personalized first line, technology stack, or any custom field. Each column uses GPT-4 or Gemini to research and fill in the data.

Optionally, use web scraping to pull data from company websites. This gives AI enrichment real-time context for generating more accurate, current insights.

Step 4: Export and Use

Export your enriched CSV from Enrichabl. The file includes all original columns plus new enrichment columns (validation status, AI-generated fields, etc.).

Import the enriched CSV into your cold email tool (Instantly, Smartlead, Lemlist) or CRM (HubSpot, Salesforce, Pipedrive). Use enrichment columns as merge fields for personalized outreach.
