Choose Lemlist from the list of available platforms.
You will see two required fields: Email and Password.

Finally, click Connect Lemlist. Your sequencer will now appear in the Sequencers list with a connected status.
Part 2: Export Your Mailboxes to LemlistAfter connecting Lemlist, you can export mailboxes manually or automatically.
Manual Export
Go to Exports in InboxKit.
Click Create Export.
Choose Lemlist as your sequencer.
Select the mailboxes you want to export.
Click Create Export Job.
Exporting usually completes within 5–30 minutes. Once done, your mailboxes will appear inside Lemlist under your sending accounts.
Auto-Export (Recommended)InboxKit also supports Auto Export, which saves you time.
When enabled:
New mailboxes you purchase and activate will automatically sync to Lemlist.
No need to manually trigger exports every time you scale.
To turn it on:
Go to Sequencers → Lemlist → Settings
Enable Auto Export
Export Failures: Common Reasons & FixesIf your export fails, it is usually due to one of the following:
1. Incorrect Credentials
Ensure:
Your Lemlist login email is correct
Your Lemlist password is correct
2. Subscription Expired in Lemlist
You must have an active Lemlist subscription. If the subscription is inactive, export will fail.
3. Two-Factor Authentication Enabled (2FA)
Lemlist does not support API login or mailbox sync with 2FA enabled. Disable 2FA temporarily from Lemlist settings.
4. Lemlist Account Limits
If your Lemlist plan has reached mailbox limits, new mailboxes cannot be added. Upgrade your plan or remove unused mailboxes.
You're All SetOnce connected and exported, your mailboxes will be ready for sending campaigns inside Lemlist—fully warmed, authenticated, and optimized by InboxKit.
