Connect Your Mailboxes to Lemlist: Everything You Need to Know

Updated this week

Zapmail makes it easy to export your mailboxes directly to Lemlist so you can start warm-up and outreach without manual setup.

This guide walks you through how to connect your Zapmail mailboxes to Apollo in just a few clicks.

This guide walks you through the complete process step by step.


Before You Begin

  • Make sure you have an active Lemlist account

  • Your mailboxes should be active


🆕 New: User-Level Export Support

Zapmail now supports user-level exports for Lemlist, allowing exports to be configured per individual user instead of being limited to the team level.

How It Works

  • API Key (Team-Level):
    Used to automatically fetch and resolve your Lemlist team

  • User Credentials (User-Level):
    Each export is mapped to a specific user using their email and password

This ensures better control and flexibility when managing multiple users within the same Lemlist team.


🔑 Requirements for Connection

To export mailboxes, you’ll need:

  • Email (Lemlist login)

  • Password (Lemlist login)

  • API Key (Team-level access)


🔍 How to Get Your Lemlist API Key

  • Open Lemlist

  • Click your profile icon (bottom-left corner) → Select Settings

  • Go to Integrations (API Settings)

  • Click Generate

  • Enter a name for your API key (e.g., Zapmail Integration)

  • Click Create Key

  • Copy and securely store your API key


🚀 How to Export Mailboxes to Lemlist

Step 1: Select Your Mailboxes

  • Go to the Mailboxes > Assigned section and check the boxes next to the mailboxes you want to export.


Step 2: Click “Export Mailboxes”

  • At the top of the page, click Export Mailboxes.


Step 3: Choose Lemlist

  • From the list of platforms, select Lemlist.


Step 4: Connect Your Lemlist Account

  • Click Export, then log in using your Lemlist credentials.

  • Fill in the following:

    • Email – the same email you use to log into Lemlist

    • Password – your Lemlist login password

    • API Key – your Lemlist team API key

This securely authorizes Zapmail to send mailboxes to your Lemlist workspace.


Step 5: Fetch Team Users & Select Export User

If you want to export mailboxes to a specific team member:

  • After adding the API Key, click Fetch Team Users

  • Zapmail will display all available team members in a dropdown

  • Select the user you want to export mailboxes to

This ensures the mailboxes are mapped to the correct user within your Lemlist team.

⚠️ Make sure the API key you generate belongs to the correct team/workspace, otherwise users may not load correctly.


Step 6: Add Lemlist Team Name

To complete the export, Zapmail requires your Lemlist Team Name.

To find it:

  • Log in to your Lemlist account

  • Go to Settings → Team Settings

  • Copy the Team Name exactly as shown

  • Paste it into the Team Name field in Zapmail


Step 7: Confirm Export

Once logged in, you’ll see a confirmation message that your mailboxes are queued for export.

Your mailboxes will automatically appear in Apollo as soon as they’re ready.


⚠️ Important Notes Before Exporting

  • User-level exports:
    Each Lemlist user requires a separate export using their own login credentials.

  • API key is mandatory:
    The API key is required to identify and map the correct Lemlist team.

  • Google Sign-In users:
    If you signed up using “Continue with Google”, create a manual password in Lemlist settings.

  • Single active session:
    Lemlist allows only one active session at a time. Avoid logging in during export to prevent interruptions.

  • 2FA support (Magic Link & OTP):
    If enabled, Lemlist will send a Magic Link and OTP to your email. Enter these in Zapmail when prompted.

  • Mailbox slot availability:
    Ensure you have enough mailbox slots available in your Lemlist account before exporting.


🎉 You’re All Set!

Once connected, your mailboxes will automatically appear in your Lemlist workspace as soon as they are ready.If you face any issues while exporting, our support team is always here to help.
