FAQ
Questions buyers ask.
- Does it replace Klaviyo?
- No. Unlapse sends the decision as an event: the customer, the products, the cart link and the reason. Your flows in Klaviyo render the email.
- How long does it take to go live?
- We tell you after the audit of your order history. The answer depends on what the history holds and on how your flows are set up, and we would rather give you a date we can keep.
- What happens to a customer who paused their subscription on Loop?
- They are never treated as lost. A paused subscriber is held out of sends instead of being sent a win-back, and stays a candidate for a nudge to resume.
- Why hold 5 percent of customers back?
- Because it is the only way to know what the emails caused. Five in every hundred, chosen by a stable hash of the customer id, never get the engine's emails. Your own newsletters still reach them, so what is measured is what the engine adds. Comparing the emailed group with them, on your own orders, separates the purchases the emails caused from the ones that were coming anyway. It costs five percent of the reach; that is the price of knowing.
- What is a calibrated score?
- A real probability. A 0.30 means a 30 percent chance that the customer takes that campaign's action within about 90 days, and it means the same thing for a reorder as for a subscription, so the two can be ranked against each other. The highest score in the system on the first brand is 0.598; nothing reads 99 percent.
- Can we switch a campaign off?
- Yes. Switching a campaign off or on is a configuration change on our side and, when you switch one on, one cloned flow on yours. A kill-switch property on the customer profile also lets you pause anyone, or everyone, from Klaviyo.
- What about customers who just bought?
- They are skipped. Someone who has just made a purchase does not need a nudge to purchase, and anyone emailed by the engine in the last 21 days is left alone too, in both the emailed and the held-back group.
- What do you see of our data?
- Read access to orders, customers and products in Shopify, a Klaviyo key that can write events, and a Loop key if your subscriptions run on Loop. The engine runs on a VM in your own cloud account, so your data stays there.
- What does “nothing” look like in a report?
- A lift whose confidence interval includes zero, reported as not distinguishable from zero, beside the attributed figures, which are labelled as attribution. If a campaign is only taking credit for purchases that were coming anyway, the report says so.
- Who else uses it?
- One brand, a subscription-driven DTC brand, has run it in production every night since July 2026. We do not have a roster of clients to show you, and we will not pretend to.
