Learning Objective
By the end of this guide, you'll know how to install the lemlist Chrome extension, use it on LinkedIn, Gmail, HubSpot, and Salesforce, enrich contacts, add leads to campaigns, and call leads directly from any platform.
Why This Matters
Switching between lemlist, LinkedIn, Gmail, and your CRM wastes time and breaks your workflow. Without the Chrome extension:
You manually copy-paste lead data between platforms
You lose context switching between tabs
You can't take action on leads where you find them
Enrichment and campaign enrollment require multiple steps
The lemlist Chrome extension (also called "lemlist everywhere"):
✅ Adds leads to campaigns directly from LinkedIn, Gmail, HubSpot, or Salesforce
✅ Enriches contacts with verified emails, phone numbers, and LinkedIn profiles
✅ Uses AI to write personalized messages
✅ Calls leads via the lemlist dialer without leaving the page
✅ Tracks emails sent from Gmail
✅ Works where you work – no tab-switching required
Prerequisites
Before using the Chrome extension:
You have a lemlist account with active campaigns
You use Google Chrome browser

Troubleshooting
Issue: lemlist panel doesn't appear on LinkedIn
Root cause: Extension not installed, or LinkedIn/lemlist not logged in.
Fix:
Verify the extension is installed (check Chrome extensions)
Log in to both lemlist and LinkedIn
Refresh the LinkedIn page
Check that the extension has permissions (right-click extension icon → Manage extension → Site access)
Issue: Can't add leads to campaign from HubSpot or Salesforce
Root cause: CRM not connected to lemlist.
Fix:
Go to lemlist Settings → Integrations
Connect HubSpot or Salesforce
Refresh your CRM page after connecting
Issue: "Find phone" doesn't return a phone number
Root cause: Phone number not available in lemlist database for this contact.
Fix:
Try enriching from LinkedIn first (LinkedIn profiles often have more data)
Use a different data source or manually add the phone number
Note: Not all contacts have publicly available phone numbers
Issue: Duplicate leads added despite settings
Root cause: Duplicate detection settings not configured, or leads have slightly different email addresses.
Fix:
Go to Chrome extension settings and enable duplicate prevention
Verify email addresses match exactly ([email protected] ≠ [email protected])
Manually check lemlist campaign Leads tab and remove duplicates if needed
Issue: Gmail templates button not showing
Root cause: Extension not enabled for Gmail, or Gmail not fully loaded.
Fix:
Refresh Gmail
Check extension permissions (should have access to mail.google.com)
Compose a new email (the button appears under the subject line)
Optimization Tips
Use bulk selection on LinkedIn: Instead of adding leads one by one, select multiple profiles from search results or Sales Navigator and add them all at once.
Set duplicate prevention early: Configure duplicate settings before your first bulk import to avoid cleanup work later.
Enrich before adding to campaigns: Click "Enrich" first to find emails and phone numbers, then add to campaigns with complete data.
Save favorite templates: Mark your best-performing templates as favorites in lemlist so they appear first in Gmail's template selector.
Call immediately after enrichment: When you find a phone number, call the lead right away while you're already on their profile—strike while the iron is hot.
Review sequences before launching: Always use "Review & Launch" to double-check sequences are personalized correctly before sending.
Train your team on duplicate settings: Make sure everyone on your team knows how to configure duplicate prevention to keep your database clean.
