Connect Your Mailboxes from InboxKit to Warmforge: Everything You Need to Know

Warmforge is designed to improve your email deliverability through intelligent warmup sequences. When paired with InboxKit, you get a streamlined pipeline: provision mailboxes, export them to Warmforge, and let the warmup begin—all without manual data entry or repetitive imports. Here's how to set it up.

Part 1: Connect Warmforge to InboxKit

The integration process is quick and painless:

Step 1: Open Sequencers

• From your InboxKit dashboard, click on Sequencers in the left sidebar.

• Press + Add Sequencer to view available platforms.

Step 2: Select Warmforge

• Find Warmforge in the list and click on it.

• The form will show three fields: Email, Password, and Workspace ID (Optional).

Step 3: Provide Your Warmforge Credentials

• Email – the email you use to access your Warmforge account

• Password – your Warmforge password

• Workspace ID (Optional) – if your Warmforge account has multiple workspaces, enter the specific Workspace ID where you want mailboxes exported. Leave this blank to use your default workspace.

Click Connect Warmforge to complete the setup. Your sequencer list will now display Warmforge as an active connection.

Part 2: Export Mailboxes to Warmforge

With Warmforge connected, pushing mailboxes over takes just a few steps.

How to export manually:

1. Visit the Exports section in InboxKit.

2. Click Create Export.

3. Choose Warmforge from your connected platforms.

4. Select the mailboxes you want to send—one, several, or all at once.

5. Confirm with Create Export Job.

The export runs in the background and typically completes in 5–30 minutes. After that, head over to Warmforge and you'll see your mailboxes ready for warmup configuration.

Auto-Export: Automate Your Warmup Pipeline

If you're regularly spinning up new mailboxes, manually exporting each batch gets old fast. Auto Export solves this.

How it helps:

• Newly activated mailboxes in InboxKit are pushed to Warmforge automatically

• Your warmup queue stays populated without extra effort

• Scale your infrastructure without scaling your workload

To switch it on:

1. Navigate to Sequencers → Warmforge → Settings

2. Enable Auto Export

Once active, every mailbox you provision flows directly into Warmforge—keeping your sender reputation on track from day one.

Troubleshooting Failed Exports

If an export doesn't go through, here's what typically causes issues:

1. Login Credentials Are Wrong

• Verify your Warmforge email and password are entered correctly

• Try logging into Warmforge directly to confirm they work

2. Workspace ID Doesn't Exist

• If you specified a Workspace ID, double-check it matches an actual workspace in your account

• Copy the ID directly from Warmforge settings to avoid typos

3. Billing or Subscription Problems

• Warmforge requires an active subscription to accept mailbox imports

• Make sure your account isn't paused or expired

4. 2FA Blocking the Connection

• Two-factor authentication interferes with automated exports

• Disable 2FA temporarily from Warmforge's security settings

5. You've Hit Your Mailbox Limit

• Warmforge plans cap how many mailboxes you can warm up at once

• Clear out finished warmups or upgrade your plan to continue

Warmup Ready

That's it—Warmforge and InboxKit are now working together. Your mailboxes will arrive in Warmforge fully authenticated with SPF, DKIM, and DMARC already configured by InboxKit. All that's left is to let the warmup do its job, and your sending reputation will be solid by the time you're ready to launch campaigns.
