# Markin + Klaviyo

> Profile properties and events for commerce lifecycle.

**Job:** Decide the moment and the offer; Klaviyo runs the flow.

A Markin and Klaviyo setup decides which lifecycle moment is worth a message for each profile and writes it back as a profile property or event, so Klaviyo flows fire on a decision with its reason instead of on a static segment rule.

Commerce lifecycle programmes usually run out of ideas before they run out of capacity. Markin supplies the next hypothesis and reads whether it was actually incremental.

## What can you ask Markin to do in Klaviyo?

- How do I win back lapsed customers in Klaviyo without discounting everyone?
- Can I add predictive next best action to Klaviyo flows?

## What Markin does in Klaviyo

- Read profile properties, list membership and consent.

- Detect lapsing customers before the usual win-back window.
- Choose between discount, content and product-led actions by expected value.
- Write the decision as a profile property with reason and expiry.
- Emit a custom event that starts the matching flow.

## The growth work behind Klaviyo

### Read the estate

- Map every customer, account, subscription and plan in the systems you already run.
- Rebuild the revenue baseline from orders, payments, refunds and credits.

### Find where revenue is leaking

- Size every finding in revenue, not in percentage points.
- Watch ARPU by cohort, plan, market, channel and tenure for drift that clears noise.

### Explain why

- Show the counter-evidence, not only the supporting cut.
- Keep the query trail so an analyst can reproduce every number.

### Write hypotheses worth funding

- Keep the full portfolio visible, including what was deliberately not funded.
- Write hypotheses continuously across marketing, product, pricing and technical health.

### Decide per customer

- Pick the channel, timing and incentive level, not only the message.
- Cap discount and margin exposure at the level finance agreed.

### Execute in the tools you already run

- Route offers, retention plays and save flows to the right surface.
- Open the work as a draft for approval where a human should sign off.

### Prove it caused the revenue

- Publish the readout in the same place for every experiment.
- Hold back a randomised control group on every decision, not one global holdout.

### Retire, govern and hand over

- Keep personal data in your systems and act on it in place.
- Show the whole decision trail when legal, finance or an auditor asks.

## FAQ

**How does Markin connect to Klaviyo?**

Attribute write-back, Triggered event. Markin writes the decision onto the customer profile; your existing journeys read it as an entry condition. Latency is the platform's sync interval.

**What does Markin read from Klaviyo?**

Profile properties and list membership; Flow and campaign engagement.

**What does Markin write back into Klaviyo?**

Profile properties carrying the chosen action Events that trigger flows

**Do we have to move our data to Markin?**

No. Markin reads from your warehouse, product events and operational systems in place, on your compute, under the access rules your data team already set. Nothing is copied into a separate customer base and there is no vendor-side profile store to migrate off later.

**Does Markin replace our engagement platform or CDP?**

No, and it should not. Your engagement platform keeps the channel, the templates, the deliverability and the governance. Your CDP keeps identity and consent. Markin adds the layer neither has: deciding which action deserves to exist for each customer, and proving it against a holdout.

**What if the system we use is not listed?**

The four activation patterns cover almost everything: attribute write-back, triggered event, decision API and direct surface rendering. Any system that exposes an API, accepts a table, or can read a warehouse column can receive decisions. New connectors are built during deployment, typically in days.
