Connect Klaviyo to MirrorNex

Last updated: August 2026

MirrorNex uses Klaviyo to send email campaigns. You'll need to connect your Klaviyo account before you can create and send campaigns.

Why Klaviyo?

Klaviyo is the leading email marketing platform for Shopify stores. By integrating with Klaviyo, MirrorNex can:

• Send professional, branded emails at scale
• Leverage your existing Klaviyo segments and lists
• Track deliverability, opens, and clicks accurately
• Comply with email marketing regulations (CAN-SPAM, GDPR)

How to connect Klaviyo

Step 1: Open the Campaigns page

In your Shopify admin, go to Apps → MirrorNex and click Campaigns in the navigation.

If Klaviyo isn't connected, you'll see a warning banner at the top of the page:

"Klaviyo integration required. Connect your Klaviyo account to start sending campaigns."

Step 2: Click Connect Klaviyo

Click the Connect Klaviyo button in the warning banner. This will open the Klaviyo authorization flow.

Step 3: Authorize MirrorNex

Log in to your Klaviyo account (if not already logged in) and authorize MirrorNex to:

• Send emails on your behalf
• Access your lists and segments
• Track campaign performance metrics

Step 4: Confirm connection

Once authorized, you'll be redirected back to MirrorNex. The warning banner will disappear, and you can now create campaigns.

Connection status

You can verify your Klaviyo connection status anytime:

• Connected: No warning banner on Campaigns page
• Not connected: Yellow warning banner appears

Troubleshooting

Authorization failed

If the authorization fails:

1. Make sure you're logged into the correct Klaviyo account
2. Check that your Klaviyo account has permission to authorize apps
3. Try disconnecting and reconnecting
