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 in Chrome

  • Log in to both lemlist and LinkedIn

  • Refresh the LinkedIn page

  • Check that the extension has site permissions

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 isn't available for this contact.

Fix:

  • Try enriching from LinkedIn first

  • Manually add the phone number if you have it

  • Note: Not all contacts have publicly available phone numbers

Issue: Duplicate leads added despite settings

Root cause: The duplicate rule wasn't reviewed before pushing, or the lead doesn't match an existing record exactly.

Fix:

  • Review the duplicate option in the bulk push drawer before confirming

  • Verify email addresses match exactly ([email protected] ≠ [email protected])

  • Manually check your lemlist campaign 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, then look under the subject line

Optimization Tips

Use bulk import on LinkedIn: Instead of adding leads one by one, import the whole search and push them in one action.

Use CRM list views for bulk actions: In HubSpot and Salesforce, select contacts directly from list views and add them to lemlist without opening each record one by one.

Review duplicate rules before bulk push: This helps keep your campaign clean from the start.

Enrich before outreach: Add email or phone data first, then push leads into a campaign with more complete contact info.

Save your best templates: Keep top-performing templates easy to access from Gmail.

Call immediately after enrichment: When you find a phone number, reach out while you're already on the profile.

Check campaign status from the profile: Use the Campaigns tab to see whether a lead is already active, paused, or ready to launch.
