This guide shows you how to connect LinkedIn to lemlist reliably, especially if your team needs to run outreach from multiple LinkedIn profiles.

Learning Objective

By the end of this tutorial, you’ll know how to connect a LinkedIn account to lemlist using the Chrome extension, and how to set up multiple LinkedIn profiles safely using separate lemlist seats and Chrome profiles.

Why This Matters

LinkedIn actions in lemlist depend on the correct browser session (cookies + the Chrome extension). If you connect the wrong LinkedIn profile, or switch profiles in the same Chrome profile, campaign steps can fail or get overwritten, creating unstable automation.

Prerequisites

You should already have access to the lemlist workspace you want to use.
You should already have access to the LinkedIn account(s) you want to connect.
You should be using Google Chrome and be able to install the lemlist Chrome extension.

Core Lesson — Step-by-Step Workflow

Phase 1: Connect a single LinkedIn account to lemlist

Install the lemlist Chrome extension.
Download and install it from the Google Chrome Store. This extension is required for LinkedIn automation.
Log in to the correct accounts in the same Chrome profile.
In that Chrome profile, log into the lemlist account you want to use, and log into the LinkedIn account you want to connect. This matters because the integration relies on the browser session.
Complete the connection flow.
After the extension is installed, the integration typically initiates automatically. You’ll see a confirmation window once the connection is successful.
If you’re unsure during setup, skip and connect later.
If you don’t want to complete the flow immediately, click Skip during setup, go directly to LinkedIn, and initiate the integration later by clicking the lemlist logo in your browser.

Optional: Connect a partner’s LinkedIn profile

You can connect a partner’s LinkedIn profile instead of your own by following the same steps above—just make sure you are logged into your partner’s LinkedIn account in the Chrome profile you’re using for the connection.

Phase 2: Manage multiple LinkedIn accounts (the stable setup)

Key rule to understand first

Each lemlist account can only connect to a single LinkedIn account. If you need multiple LinkedIn profiles, you must use separate lemlist seats/accounts and keep each connection isolated in its own Chrome profile.

Important: If you disconnect a LinkedIn account used in an active campaign and connect another, the campaign actions tied to the old account will no longer function. Pause or finish campaigns before switching accounts.

Create separate lemlist seats/accounts for each LinkedIn profile.
Add seats under your lemlist subscription so each LinkedIn profile has its own lemlist login and its own one-to-one LinkedIn connection.
Use different Chrome profiles for each LinkedIn + lemlist pair.
To connect multiple LinkedIn accounts from the same computer:
1. Create a separate Chrome profile for each LinkedIn/lemlist connection.
2. In that Chrome profile, log into the matching LinkedIn account and the matching lemlist account.
3. Install the lemlist Chrome extension in that Chrome profile.
4. Complete the LinkedIn connection for that lemlist account.

Important: If you attempt multiple LinkedIn connections using the same Chrome profile, switching between accounts can overwrite existing integrations, leading to unstable setups.

Practical Application / Real-Life Example

If your team runs outreach from three LinkedIn profiles, the stable setup is:

3 lemlist seats/accounts (one per LinkedIn profile)
3 Chrome profiles (each with the lemlist extension installed)
Each Chrome profile stays logged into exactly one LinkedIn account and its matching lemlist account

This prevents accidental overwrites and ensures campaign actions run from the intended LinkedIn profile.

Troubleshooting & Pitfalls

Issue: LinkedIn actions stop working after switching accounts
Root cause: The LinkedIn connection is tied to cookies in the current Chrome profile, and switching accounts can break or overwrite the session.
Fix:
- Use one Chrome profile per LinkedIn account.
- Confirm you’re logged into the correct LinkedIn and lemlist accounts in that profile.
- Avoid disconnecting/reconnecting during an active campaign.
Issue: Message says your LinkedIn must be disconnected from another lemlist account
Root cause: The same LinkedIn profile is already linked to a different lemlist account.
Fix:
1. Disconnect your LinkedIn account from any other lemlist accounts.
2. Be aware that active campaigns associated with the account will stop once it’s unlinked.
Issue: Connection keeps dropping
Root cause: Logging out of LinkedIn clears/changes the session cookies the integration relies on.
Fix:
- Stay logged into LinkedIn in the Chrome profile used for lemlist actions.
- Keep using the same Chrome profile consistently for that LinkedIn/lemlist pair.

Knowledge Check (Optional)

Which LinkedIn account is currently logged into the Chrome profile you’re using for lemlist?
Do you have one lemlist seat/account per LinkedIn profile you want to automate?
Have you paused or finished any campaigns before disconnecting a LinkedIn account?
