With the connection established, moving mailboxes into Warmy.io is effortless.

Manual Export Walkthrough:

Auto-Export: Continuous Warmup Without the Busywork

Adding mailboxes frequently? Skip the manual exports with Auto Export.

Why it matters:

• New mailboxes automatically flow from InboxKit to Warmy.io upon activation

• Warmup begins without delay—no human intervention required

• Your growing infrastructure stays protected with consistent reputation building

Turning it on:

1. Head to Sequencers → Warmy.io → Settings

2. Toggle Auto Export to enabled

This feature is especially powerful for agencies and teams managing large-scale cold email operations where mailboxes are added weekly or even daily.

Export Issues? Here's How to Fix Them

When exports fail, one of these common culprits is usually responsible:

1. Credentials Don't Match

• Ensure the email and password are exactly what you use on Warmy.io

• Check for accidental spaces before or after your entries

2. Signed Up with Google?

• If you created your Warmy.io account via Google OAuth, you won't have a password by default

• Visit Warmy.io account settings to set a password, then use those credentials in InboxKit

3. Subscription Not Active

• Warmy.io requires a paid plan to import and warm up mailboxes

• Verify your account is active and in good standing

4. Two-Factor Authentication Is On

• 2FA blocks the automated login that InboxKit uses to export

• Temporarily disable 2FA in your Warmy.io security settings

5. Warmup Slots Exhausted

• Each Warmy.io plan has a limit on concurrent warmup mailboxes

• Remove mailboxes that have finished warming or upgrade to a higher tier

Your Warmup Pipeline Is Complete

And that's a wrap! Warmy.io and InboxKit are now connected. Every mailbox you export arrives with proper email authentication already in place—SPF, DKIM, and DMARC configured by InboxKit. Warmy.io takes it from there, building your sender reputation so when launch day comes, your emails land where they belong: the inbox.
