## Short answer

Klaviyo flow rebuilds after a replatform go in revenue order, so limited hours go first to abandoned cart, at $6.77 per email recipient on average ([Klaviyo benchmark report](https://www.klaviyo.com/blog/abandoned-cart-benchmarks), October 2026). No other flow earns more, and the top 10% of brands reach $13.70. Welcome and post-purchase follow. Browse abandonment waits for verified onsite tracking; winback waits longest.

- **Abandoned cart email, average:** $6.77 per recipient. The highest average of any flow in Klaviyo's 2026 benchmark of more than 110,000 customers; $4.48 for text messages ([Klaviyo, The abandoned cart benchmarks report: 2026 data to inform your strategy](https://www.klaviyo.com/blog/abandoned-cart-benchmarks))
- **Abandoned cart email, top 10%:** $13.70 per recipient. 3.24% above the welcome flow, the second-highest flow among top performers, in the same Klaviyo report ([Klaviyo, The abandoned cart benchmarks report: 2026 data to inform your strategy](https://www.klaviyo.com/blog/abandoned-cart-benchmarks))
- **Flow trigger after a replatform:** Cannot be changed; clone the flow. Flows on the old platform's metrics queue no one once its data stops, so Klaviyo has you clone each onto the new metric and hold it in Draft or Manual ([Klaviyo Help Center, How to update Klaviyo after switching ecommerce platforms](https://help.klaviyo.com/hc/en-us/articles/360003124151); [Klaviyo Help Center, How to create a metric-triggered flow](https://help.klaviyo.com/hc/en-us/articles/360003057151))
- **Abandoned Cart trigger on Shopify:** Checkout Started metric. Fires once the shopper enters an email, per Klaviyo's Shopify data reference; Klaviyo's general flow guide still calls the trigger Started Checkout ([Klaviyo Help Center, Shopify data reference](https://help.klaviyo.com/hc/en-us/articles/115005080447); [Klaviyo Help Center, How to create a metric-triggered flow](https://help.klaviyo.com/hc/en-us/articles/360003057151))

## Deploi's call

Rebuild in revenue-per-recipient order using your own last-90-days numbers, verify triggers before content, and spend the first hour writing the list of flows you will not rebuild.

**CUSTOMIZE: Rebuild in revenue order when**

- Klaviyo stays and only the store moved, so each metric-triggered flow is cloned onto the new store's events ([Klaviyo Help Center](https://help.klaviyo.com/hc/en-us/articles/360003124151), October 2026).
- You can rank each flow by its own revenue per recipient from before the replatform.
- Each trigger passes a live test on the new store before content work starts. Deploi's abandoned checkout recovery record scores that tracking audit CUSTOMIZE ([Deploi decision record](https://deploi.ca/shopify/build-vs-buy/abandoned-checkout-recovery), October 2026).

**DEPENDS: Change the order when**

- A flow carries consent confirmations or transactional messages, which go first.
- Subscription flows earn more per recipient than abandoned cart.
- The email service provider (ESP) changes too, because Klaviyo's warming guide holds an abandoned cart flow without a strong history until 30 days of campaigns ([Klaviyo's warming guide](https://help.klaviyo.com/hc/en-us/articles/20413890435355), October 2026).

## Which Klaviyo flow should a mid-market brand rebuild first after a replatform?

A mid-market brand should rebuild the Klaviyo abandoned cart flow first after a replatform, because it earns the most per recipient and its trigger changed with the platform. Klaviyo analyzed more than 110,000 customers for its 2026 benchmark. Abandoned cart flows earn the highest average revenue per recipient of any flow: $6.77 for email and $4.48 for text messages ([Klaviyo benchmark report](https://www.klaviyo.com/blog/abandoned-cart-benchmarks), October 2026). The top 10% of brands reach $13.70 and $8.69.

That top-decile email figure is about twice the average (Deploi arithmetic from the figures above), which means the rebuild is a chance to improve the flow rather than transcribe it. The benchmark is cross-industry, so your own flow's revenue per recipient over the 90 days before the replatform is the better input. Use the benchmark to sanity-check, not to plan. This order assumes Klaviyo stays: [the Klaviyo, Omnisend and Attentive comparison](https://deploi.ca/shopify/faq/klaviyo-vs-omnisend-vs-attentive-20m-100m-gmv) settles the platform.

## In what order should the other Klaviyo flows come back after a replatform?

The other Klaviyo flows come back by revenue, support load and trigger risk.

**Deploi's rebuild order for Klaviyo flows after a replatform, by revenue, support load and trigger risk**

| Flow | Rebuild order | Why it sits here |
| --- | --- | --- |
| Abandoned cart | 1 | Highest revenue per recipient; its trigger moves to Shopify's Checkout Started metric |
| Welcome | 2 | Subscribers arrive from day one; second-highest revenue per recipient among top performers |
| Post-purchase and shipping | 3 | Deflects support tickets while the new site generates the most; its template tags change |
| Back-in-stock | 4 | Depends on inventory data being right after migration; verify before enabling |
| Browse abandonment | 5 | Depends on Klaviyo's onsite tracking, which starts only once the app embed is on |
| Winback and lapsed | 6 | Runs on historical data rather than new events, so it is safe to defer |
| Everything else | 7 | The long tail: rebuild what earns, retire the rest |

## Which Klaviyo flows should not be rebuilt after a replatform?

Klaviyo flows that no longer earn should not be rebuilt after a replatform, and listing them is the most valuable hour in the project. Most mid-market Klaviyo accounts we see carry flows built for an old campaign, duplicates from an A/B test nobody concluded, and flows whose trigger no longer exists.

1. Export flow-level revenue for the last 12 months before anyone tidies the account. Deleting the old platform's metrics also deletes all historical data tied to them, Klaviyo warns ([Klaviyo Help Center](https://help.klaviyo.com/hc/en-us/articles/360003124151), October 2026).
1. Sort the flows by revenue, descending, and draw a line.
1. Retire everything below the line, so the rebuild hours go to flows that earn.

This is the only step that makes the program smaller, and a replatform is the only moment when nobody will argue about it.

## How do you check a Klaviyo flow's trigger on the new store before rebuilding its content?

Check each Klaviyo flow's trigger with a live test on the new store before rebuilding its content, because a flow with perfect copy and a dead trigger sends nothing, quietly. Once the old store stops sending data, flows on its metrics queue no one. Klaviyo will not let you change a flow's trigger metric ([Klaviyo's flow guide](https://help.klaviyo.com/hc/en-us/articles/360003057151), October 2026). Instead, you clone each flow onto the new metric and hold the clone in Draft or Manual until cutover ([Klaviyo Help Center](https://help.klaviyo.com/hc/en-us/articles/360003124151), October 2026).

On Shopify, Klaviyo's Abandoned Cart flow fires on the Checkout Started metric once a shopper enters an email ([Klaviyo's Shopify data reference](https://help.klaviyo.com/hc/en-us/articles/115005080447), October 2026). Klaviyo's flow guide still calls that trigger Started Checkout, so search for both names. Viewed Product tracks only once the Klaviyo app embed is on. Added to Cart can arrive without the shopper's identity unless Shopify Network Intelligence is enabled ([Klaviyo's Shopify setup guide](https://help.klaviyo.com/hc/en-us/articles/115005080407), October 2026).

For each flow, in order:

1. Abandon a checkout and place a test order on the new store.
1. Confirm the event reaches Klaviyo with the properties the flow filters on.
1. Rebuild the content, swapping the old platform's template tags in abandoned cart, post-purchase, thank-you and review flows ([Klaviyo Help Center](https://help.klaviyo.com/hc/en-us/articles/360003124151), October 2026).

[Deploi's abandoned checkout recovery record](https://deploi.ca/shopify/build-vs-buy/abandoned-checkout-recovery) calls for the same end-to-end trace before any template work (October 2026).

## How do you keep Klaviyo flows earning during the replatform cutover?

Keep Klaviyo flows earning during the cutover by leaving the old flows live until the old store stops sending events. Then switch each cloned flow live as the new store takes orders. The clones exist because Klaviyo will not change a flow's trigger, so each metric-triggered flow is copied onto the new store's metric ([Klaviyo Help Center](https://help.klaviyo.com/hc/en-us/articles/360003124151), October 2026).

- **Size the gap.** A dark abandoned cart flow is the most expensive kind of caution, and [the dark-window sizing in our abandoned cart migration answer](https://deploi.ca/shopify/faq/abandoned-cart-records-recovery-email-migration) prices it from your own last 90 days.
- **Switch off Shopify's duplicate.** Shopify can send its own abandoned checkout emails through an automation in the Shopify Messaging app ([Shopify Help Center](https://help.shopify.com/en/manual/promoting-marketing/create-marketing/abandoned-checkouts), October 2026). Klaviyo says turning Shopify's notification off is a manual step ([Klaviyo's Shopify data reference](https://help.klaviyo.com/hc/en-us/articles/115005080447), October 2026). Leave both on, and shoppers get two recovery emails.
- **Log any dark period.** If a flow must go dark, write down the date it went dark and the date it came back. That record is how anyone explains the revenue chart at the next quarterly review.

## When should a brand not follow this Klaviyo rebuild order?

Change the Klaviyo rebuild order when the law, the business model, broken tracking or a new email platform outranks revenue per recipient.

> **When not to do this**
> - **When a flow is legally load-bearing.** Consent confirmations and transactional messages are not in a revenue priority list. They go first and they are not negotiable.
> - **When the brand is subscription-led.** Subscription lifecycle flows can outrank abandoned cart on revenue per recipient, so check your own data.
> - **When onsite tracking is already known to be broken.** Fix the tracking before the flows, or you will rebuild against signals that are not arriving.
> - **When the replatform also changes email service provider (ESP).** Sequence deliverability first. For flows without a strong history, Klaviyo's warming guide says to turn on welcome after 2 weeks of campaigns, abandoned cart after 30 days and browse abandonment after 30 to 60 days ([Klaviyo's warming guide](https://help.klaviyo.com/hc/en-us/articles/20413890435355), October 2026). [How long a Klaviyo migration takes](https://deploi.ca/shopify/faq/klaviyo-migration-timeline-from-mailchimp-activecampaign) covers the warming paths.

## Deploi's point of view

**What we've seen.** The flow that breaks silently in a replatform is almost always browse abandonment, because it depends on onsite tracking rather than on an order event, and nobody notices for weeks because a flow sending zero emails generates no complaints. Putting it late in the order and verifying its trigger explicitly is worth more than rebuilding it early.

**Where we disagree.** The standard advice is to rebuild everything before go-live so nothing is missing. That guarantees the highest-revenue flow is built by a tired team in the same week as the lowest-revenue one. We would rather ship three flows verified end to end than eleven flows nobody tested, and a replatform is the right moment to shrink a program rather than faithfully reproduce it.

**What this page adds.** The parent answer chooses the email platform; this page sequences the Klaviyo rebuild after the store moves. It adds Klaviyo's 2026 abandoned cart benchmark, a seven-step order with the reason for each position, Klaviyo's rule that a flow's trigger cannot be changed, so every metric-triggered flow is cloned, and a deprecation list as the first deliverable.

## When this answer changes

- Klaviyo publishes a new benchmark that changes which flow earns the most per recipient.
- Klaviyo lets a flow's trigger metric be changed without cloning the flow.
- Klaviyo renames Shopify's Checkout Started metric or aligns its flow guide on one name.
- Shopify changes how the Klaviyo app embed or Network Intelligence passes onsite events.
- Deploi's abandoned checkout recovery record changes its CUSTOMIZE verdict.
