## 📤 **Part 2: Export Your Mailboxes to Instantly**

After connecting Instantly, you can export mailboxes manually or automatically.

### **Manual Export**

1.  Go to **Exports** in InboxKit.
    
2.  Click **Create Export**.
    
3.  Choose **Instantly** as your sequencer.
    
4.  Select the mailboxes you want to export.
    
5.  Click **Create Export Job**.
    

Exporting usually completes within **5–30 minutes**.  
Once done, your mailboxes will appear inside Instantly 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 Instantly.
    
-   No need to manually trigger exports every time you scale.
    

To turn it on:

-   Go to **Sequencers → Instantly → Settings**
    
-   Enable **Auto Export**

## ❗ **Export Failures: Common Reasons & Fixes**

If your export fails, it is usually due to one of the following:

### **1\. Incorrect Credentials**

Ensure:

-   Your **Instantly login email** is correct
    
-   Your **Instantly password** is correct
    
-   Your **Workspace Name** matches exactly (case-sensitive)
    

### **2\. Subscription Expired in Instantly**

You must have an **active Instantly subscription**.  
If the subscription is inactive, export will fail.

### **3\. Two-Factor Authentication Enabled (2FA)**

Instantly does **not** support API login or mailbox sync with 2FA enabled.  
Disable 2FA temporarily from Instantly settings.

### **4\. Instantly Account Limits**

If your Instantly plan has reached:

-   Mailbox limits
    
-   Workspace limits
    

…new mailboxes cannot be added.

## 🎯 **You're All Set**

Once connected and exported, your mailboxes will be ready for sending campaigns inside Instantly—fully warmed, authenticated, and optimized by InboxKit.
