Partners
Retention runs on more than one tool. When your pop-ups, store, subscriptions, tracking and shipping all feed Klaviyo the same customer data, every flow goes out at the right moment. These are the partners we use every day to make that happen.

We build cancel flows on your real cancel reasons, set up failed payment recovery and run winback offers in Loop.
Loop events then trigger the Klaviyo emails around them: upcoming order, card update and winback.
We set up and test the on-site pop-ups that grow your email and SMS list.
Every sign-up and quiz answer lands in Klaviyo, so the welcome flow knows who just joined and what they came for.
We set up server-side tracking so Shopify orders and subscriptions show up correctly in Klaviyo and Google Analytics.
Clean data means flows fire on the right events and revenue is credited to the channel that earned it.
ParcelWILL Order Tracking (formerly ParcelPanel)
We send ParcelWILL shipping and delivery events into Klaviyo.
Post-purchase emails then go out when the parcel actually ships, arrives or gets stuck, not on a guessed delay.
How it connects
Klaviyo sits in the middle. Everything else either brings it new people or tells it what just happened.
Alia turns visitors into subscribers. Shopify turns them into customers. Both land in Klaviyo with their source attached.
Littledata keeps order and subscription data accurate. ParcelWILL says when a parcel ships and arrives, so post-purchase timing is real.
Loop and Klaviyo talk both ways: cancel attempts, failed payments and skips trigger emails, and emails send people back to the portal.

FAQ
No. Klaviyo and Shopify are the only must-haves. We work with the tools you already run, and only suggest adding one when it fixes a real gap, like wrong attribution or post-purchase emails going out before the parcel arrives.
We know these tools inside out and have a direct line to each partner's team. When something breaks, we escalate it instead of waiting in a support queue, and we hear about new features early enough to plan around them.
Yes. We move the subscriptions, set up cancel flows and payment recovery in Loop, then rebuild the Klaviyo side so nothing breaks on the way. Read our Skio to Loop guide for how it works.
