How to enrich leads during and after import

Step-by-step guide to enriching lead data during CSV import, from within a campaign, and from Contacts — including how to re-enrich existing records.

Use these workflows to enrich lead data at any stage — from the dedicated Enrichment tab, directly inside a campaign, or from your Contacts database.


Phase 1: Enrich a CSV from the Enrichment tab

Step 1: Open the Enrichment tab and choose CSV enrichment

Go to Enrichment, click Enrich new leads, then select From a .CSV.

Step 2: Upload your CSV file

Upload the CSV file that contains the contacts you want to enrich, then click Next.

Step 3: Map your CSV columns

Match your CSV columns to the available enrichment inputs before continuing. In this flow, you can map only these default fields: First name, Last name, Email, LinkedIn URL, LinkedIn Sales Nav URL, Company name, Company domain, Company LinkedIn URL, and Job title.

If a column doesn’t match one of these default fields, leave it unmapped.

Step 4: Choose the enrichments to run

Select the enrichment actions you want to run on the imported contacts. You’ll also see the estimated credit cost before starting.

Step 5: Start and monitor enrichment

After you click Start enrichment, lemlist shows a processing status for the CSV and a confirmation toast that the enrichment has started.

While the enrichment is running, you can track the progress directly from the Status column.

If needed, click the X next to the file to cancel the enrichment while it is still processing.

Phase 2: Enrich after import from the campaign lead list

The flow for enriching leads directly from a campaign remains the same.

After your leads are imported, open the campaign’s Leads list, click Enrich leads in the top-right corner, then choose the action you want, such as finding phone numbers, finding verified emails, finding LinkedIn profiles and enriching data, verifying primary emails, using AI, or opening Enrichment stats.

To review deliverability and enrichment performance, open Enrichment stats. You’ll see overall deliverability plus enrichment progress for email addresses, phone numbers, LinkedIn profiles, and email verification.

Phase 3: Enrich or re-enrich from Contacts

Use this workflow to enrich selected contacts directly from your database without adding them to a campaign first, or to re-enrich contacts that already have data.

Step 1: Select contacts and open Enrichment

Go to Contacts, select the contacts you want, then click Enrichment.

Select contacts and click Enrichment

Step 2: Pick enrichment options

Choose the enrichment you need, such as finding phone numbers, finding verified emails, finding LinkedIn profiles and enriching data, or verifying primary emails.

Step 3: Confirm re-enrichment if data already exists

If lemlist detects that some data was already enriched, confirm whether you want to enrich those records again.

Step 4: Track progress or cancel enrichment

Once enrichment starts, you’ll see a progress notification and can cancel it if needed.

Step 5: Review enriched values in Contacts

After enrichment finishes, review the updated values directly in your contact list. Enriched fields can show status indicators, such as a LinkedIn enrichment marker on the contact record.

Optimization tips

Verify before sending - Always verify emails before launching cold campaigns to reduce bounces.

Enrich strategically - Enrich the leads you’ll actually contact, not your entire database.

Re-enrich stale data - Roles and companies change over time, so re-enrich key segments when data looks outdated.
