By the end of this guide, you'll know how to use lemlist's four enrichment options (Email Finder & Verifier, LinkedIn Enrichment, Email Verification, Phone Number Finder), understand credit costs, apply enrichments during import or after, and interpret enrichment results.

Complete, verified lead data is essential for successful outreach. Missing emails means you can't contact prospects. Invalid emails cause bounces that damage your sender's reputation. Missing phone numbers limit your multi-channel approach. Enrichment fills these gaps automatically, finding emails, verifying deliverability, extracting LinkedIn data, and locating phone numbers, so you can focus on outreach rather than manual research.

Before you start:

Lemlist offers four enrichment tools:

1. Email Finder & Verifier

2. LinkedIn Enrichment

3. Email Verification (Debounce)

4. Phone Number Finder

When emails are verified (via Email Finder & Verifier or Email Verification), lemlist assigns a deliverability status:

✅ Deliverable:

⚠️ Risky:

❌ Undeliverable:

❓ Unknown:

💡 Why verification matters: High bounce rates damage your email reputation. Email providers (Gmail, Outlook) see too many bounces and start filtering your future emails to spam. Verification prevents this.

Method 1: Enrich During Import

Step 1: Start import process

Import leads via CSV, Chrome extension, or LinkedIn URL

Follow import steps until you reach enrichment options (typically page 3 of import flow).

Step 2: Select enrichment options

On the enrichment page, choose which enrichments to apply:

You can select multiple options simultaneously.

Step 3: Understand requirements

Each enrichment type requires specific input data:

Email Finder & Verifier requires:

LinkedIn Enrichment requires:

Email Verification requires:

Phone Number Finder requires:

💡 Import tip: LinkedIn import, Sales Navigator import or lemlist People database imports automatically gather First Name, Last Name, and LinkedIn URL for enrichment.

Step 4: Confirm and import

Click Import or Continue

Enrichment begins automatically during the import process.

Step 5: Track enrichment progress

Progress indicator shows enrichment status

See how many leads have been enriched so far

Typically completes within seconds, occasionally delayed by external factors.

✅ Success indicator: Yellow star ⭐ appears next to enriched leads. Grey star indicates enrichment failed.

Method 2: Enrich After Import (Campaign Leads)

Step 1: Navigate to campaign leads

Open your campaign

Go to Leads section

View list of imported leads.

Step 2: Select leads to enrich

Option A - Select specific leads: Check boxes next to individual leads

Option B - Select all leads: Use select all option for bulk enrichment

Step 3: Open enrichment menu

Select your desired enrichment option from dropdown menu.

Step 4: Confirm enrichment

Choose enrichment type

Confirm action

Enrichment begins processing.

Step 5: View enrichment results

Hover over the enrichment stats icon in your campaign to see each lead's status

Yellow star ⭐ indicates successful enrichment

Grey star indicates enrichment failed.

Method 3: Bulk Enrich from Contacts Section

Step 1: Navigate to Contacts section

Click Contacts in the left sidebar

View your full contacts list.

Step 2: Select contacts to enrich

Select contacts individually or use bulk selection

Step 4: Track enrichment

Toggle visibility:

Step 1: Open lead list

💡 Transparency: Full visibility into your data quality and credit usage per lead helps you optimize enrichment strategy.

Important billing update:

Credits used for enrichment are charged to the user who performed the action, not a default integration user. This applies when:

💡 Why this matters: Team members using their own credits encourages mindful enrichment. Admins can track who's using credits and optimize team workflows.

Use Email Finder & Verifier when:

Use LinkedIn Enrichment when:

Use Email Verification (Debounce) when:

Use Phone Number Finder when:

Issue: Enrichment shows a grey star (failed)

Root cause: Missing required data, lead not found in databases, or incorrect information provided

Fix: Verify you provided the correct input data (check spelling of names, company). Some leads may not have publicly available emails or phone numbers. Enrichment can't find what doesn't exist publicly. Try alternative enrichment types (e.g., if Email Finder fails, try LinkedIn Enrichment first to get profile data).

Issue: Email verification shows "Unknown" status

Root cause: The email provider didn't respond to the verification request

Fix: "Unknown" means uncertain deliverability. Use cautiously. For critical campaigns, manually verify by checking if the company domain is correct and the email format is standard.

Issue: Charged credits, but no data found

Root cause: Misunderstanding of billing. Enrichment is only charge when data is successfully found

Fix: Check credit transaction details. Email Finder & Verifier only charges for deliverable/risky emails found. Phone Finder only charges when a phone number is found. If charged without results, contact support with specific lead examples.

Issue: Enrichment is taking a long time to complete

Root cause: Large batch enrichment, external data source delays, or system load

Fix: Enrichment typically completes in seconds but can take longer for large batches (100+). Check back after a few minutes. Refresh the page to see updated results. For very large enrichments, use Contacts section filters to check progress (e.g., filter for "Email is not empty").

Issue: Can't find enrichment options during import

Root cause: Skipped enrichment page in import flow, or enrichment not available for import method

Fix: Enrichment options appear on page 3 of import flow, don't skip steps. If not visible, complete import first then use Method 2 (enrich from campaign) or Method 3 (enrich from Contacts).

Issue: LinkedIn enrichment not finding the LinkedIn URL

Root cause: Insufficient data provided, or the profile doesn't exist publicly with the provided name/company combination

Fix: Provide accurate First Name, Last Name, Company Name, Company Domain, and Email for best results. Check if LinkedIn profile actually exists by manually searching. Some people don't have LinkedIn profiles or use different names professionally.

Verify before sending - Always run Email Verification (1 credit) or Email Finder & Verifier (5 credits) before launching cold campaigns. Prevents bounces that damage the sender's reputation.

Enrich strategically - Don't enrich the entire database at once. Enrich batches as needed for specific campaigns. Saves credits for leads you'll actually contact.

Filter before enriching - In the Contacts section, filter to the segment you need (e.g., "Tech companies without phone numbers"), then bulk enrich only those contacts. Prevents wasting credits on leads you won't use.

Check requirements - Before enriching, verify you have the required input data.

Monitor credit usage - Track enrichment costs in lead detail modals. If credit costs are high, review if you're enriching appropriate leads or using the wrong enrichment type.

Prioritize high-value leads - Phone Number Finder costs 20 credits. Reserve for qualified prospects or high-value accounts. Don't use on the entire database.

Re-enrich stale data - LinkedIn profiles and job titles change. Re-enrich important contacts every 6-12 months to keep data current.

Use LinkedIn Enrichment for research - At 1 credits, LinkedIn Enrichment is cost-effective for gathering profile data, job titles, and company info before deciding if the lead is worth pursuing.
