Short answer

Email Kong is a Klaviyo Master Platinum Partner that builds Klaviyo retention for subscription brands on Checkout Champ. We bring the subscription events Checkout Champ's Klaviyo plugin leaves out, such as failed rebills, cancels, pauses and upcoming charges, into Klaviyo, then build the lifecycle flows that run on them. The setup is a fixed price, then a monthly retainer.

Who this is for

DTC brands that sell subscriptions through Checkout Champ and use Klaviyo for email and SMS. Most of them came to Checkout Champ for its funnels, upsells and payment gateway choice. Then they found that Klaviyo only knows about orders.

If any of these sound familiar, this page is for you:

  • Your Klaviyo shows first orders and very few renewals.
  • Nobody gets an email when a rebill declines.
  • Cancelled subscribers keep getting "your next box" campaigns.
  • You moved off Shopify with Recharge or Loop, and your subscription flows went quiet.

What Checkout Champ sends to Klaviyo, and what it misses

Checkout Champ Klaviyo agency setup: the native plugin sends orders, 8 postbacks go through an event bridge into Klaviyo, and each powers one of 8 lifecycle flows
The plugin sends orders. The subscription lifecycle comes in through postbacks.

Checkout Champ's native Klaviyo plugin sends order and checkout events. The subscription lifecycle lives in Checkout Champ's postbacks, which the plugin does not use.

What we build

Example emails from a Checkout Champ Klaviyo agency build: failed payment with an update card button, paused with resume, winback with reactivate
One portal button per email, each opening the right page in the Checkout Champ portal.

1. The subscription event bridge. We connect Checkout Champ's postbacks to Klaviyo, so 8 subscription events land on the right profile: Subscription Started, Pre-Billing, Recurring Order, Rebill Decline, Recycle Failed, Cancel, Pause and Reactivate. We drop duplicates from Checkout Champ's retries, add the fields the postback leaves out (next bill date) and filter out other brands' campaigns in shared accounts. How it works is explained in subscription events in Klaviyo.

2. 8 lifecycle flows.

Cancel save and winbackCancel

3. One-tap portal buttons. Emails carry buttons that open the right page in the customer's Checkout Champ portal: update card, resume, reactivate and pause. The customer lands on the action they need without hunting through the portal. We keep these out of pre-renewal emails, since the portal is also where people cancel.

4. Autoresponders switched off. Checkout Champ has its own emails for cancellation, pause, pre-billing and declined rebills. We switch them off before the Klaviyo flows go live so nobody gets 2 emails for 1 event.

Proof

HolySwish, an oral care brand, moved its subscriptions off Loop to Checkout Champ in September 2026. In October we set up the event bridge and the subscription flows: onboarding, failed payment, cancelled, paused, upcoming payment, order reminder and cross-sell. Subscription events were flowing into Klaviyo within days.

How an engagement works

How a Checkout Champ Klaviyo agency engagement works: free 20-minute check, fixed-price setup, retainer from $5,000 a month
Free check, fixed-price setup, then a monthly retainer. First flow live within 72 hours of access.
  1. Free Checkout Champ subscription check. A 20-minute call. We look at what your Checkout Champ sends to Klaviyo, whether rebills reach it, which subscription emails are missing and whether Checkout Champ autoresponders double-send.
  2. Fixed-price setup. The event bridge, the 8 flows, the portal buttons and the autoresponder switch-off. The Checkout Champ setup is a fixed price, quoted after the free check.
  3. Monthly retainer. Campaigns, testing and ongoing flow work. Retainers start from $5,000 a month, with a 3-month minimum and 4 weeks notice.

Onboarding takes 1 week, and the first flow is live within 72 hours of access. We need staff access to Checkout Champ (to set up postbacks and check autoresponders) and to Klaviyo.

frequently asked questions.

Does Checkout Champ integrate with Klaviyo?

Yes. Checkout Champ has a native Klaviyo plugin that sends checkout, order, fulfillment, refund and subscription restarted events. It does not send failed rebills, cancels, pauses or upcoming charges, so those need postbacks.

Who is the best agency for Checkout Champ and Klaviyo?

Look for an agency that has connected Checkout Champ postbacks to Klaviyo on a live account and built subscription flows on them. Email Kong has done this for HolySwish and is a Klaviyo Master Platinum Partner.

What does a Checkout Champ Klaviyo setup cost?

Retainers start from $5,000 a month. The Checkout Champ setup is a fixed price, quoted after the free check, because it depends on how many brands and campaigns sit in your account.

How long does it take?

Onboarding takes 1 week and the first flow is live within 72 hours of access. For HolySwish, subscription events were flowing into Klaviyo within days of the postbacks going live.

Do you work with Konnektive accounts?

Yes. We work with brands coming from Konnektive. We start with the free check of your own Checkout Champ account, so we see what reaches Klaviyo and which subscription events are missing.

Do we still need Churn Buster?

Not necessarily. If you use it and it works, keep it, and we build the Klaviyo flows around it so the 2 don't send the same message.
