Email Kong is a retention agency for subscription brands on Shopify. We are a Loop partner and a Klaviyo Platinum Partner, so one team runs your Loop setup and the Klaviyo emails and SMS around it.
In Loop, we build cancel flows on your real cancel reasons, set up failed payment recovery with retry strategies split by failure reason, run winback offers and benefits page tests, and make skip, swap and frequency changes easy to find in the portal.
In Klaviyo, we run the welcome and post-purchase flows that get subscribers past order 3, the upcoming order and card-update messages, and winback flows triggered by Loop events. We also move brands to Loop from other subscription apps and rebuild the Klaviyo side after the move.
Across the subscription brands we run on Loop, the #1 cancel reason is having too much product, about 23% of cancel attempts in the last 90 days. So we answer it with skip and slower frequencies before any discount.
Results: Kaori (women's health) went from 3.3% to 19% of store revenue from Klaviyo, Penrose Skin from 15.2% to 23.2%, and KittySpout (pet) gets 46% of store revenue from Klaviyo. We work with DTC brands doing $3M to $50M a year in the US and UK.

Save subscribers in the cancel flow
We rebuild cancel reasons in your customers' words and answer each one with the right option: skip or a slower frequency for too much product, a swap for taste, a pause for a break, one discount for price.
Recover failed payments
Retry strategies split by failure reason, a card-update SMS a few hours after the failure, card-expiry emails before the card fails, and a pause instead of a cancel at the end.
Move to Loop without losing subscribers
We plan the switch from your current subscription app with Loop, then rebuild the Klaviyo flows and events that depend on it so no reminder or card-update email goes missing after the move.
We connect Loop to Klaviyo so Loop events (subscription created, upcoming order, billing attempt failed, subscription cancelled) trigger Klaviyo flows. Cancel flows, retry strategies, quick actions and portal settings are set up inside Loop.
“Email Kong has been an incredible resource for our Shopify store. I've been consistently impressed with their CRM knowledge and work product. They have helped elevate our email strategy significantly and we've seen a major lift in average order value.”
