The 7 Must-Have Klaviyo Email Flows for Every Shopify Store (2026 Guide)

Every Shopify store should run seven Klaviyo email flows: welcome series, abandoned cart, browse abandonment, post-purchase, win-back, VIP/loyalty, and back-in-stock. Together these Klaviyo email flows Shopify merchants rely on typically generate 25 to 30% of total email revenue from a small fraction of total sends, making Shopify email automation one of the highest-return channels available to store owners.

What Are Klaviyo Email Flows and Why Do Shopify Stores Need Them?

Klaviyo flows are automated email sequences triggered by a specific customer action, such as joining your list, abandoning a cart, or completing a purchase. Unlike one-off campaigns, which you plan and send manually, Shopify email automation runs continuously in the background once it is built.

That distinction matters more than most store owners realise. Industry benchmark data compiled for 2026 consistently shows automated flows earning many times more revenue per recipient than standard campaigns, while representing only a small share of total email volume. In other words, a handful of well-built Klaviyo automated flows can outperform a much larger volume of manual sends, because each email is relevant to exactly where that customer is in their journey. This is a pattern our team at RankMyShopify sees consistently across the Shopify stores we work with: the stores getting the most out of email are rarely the ones sending the most, they are the ones with the tightest flow coverage.

For Shopify stores specifically, this works because Klaviyo’s native Shopify integration pulls in order history, product catalogue data, and on-site behavioural events such as Viewed Product, Added to Cart, and Started Checkout. That data feeds directly into flow triggers, so the right email goes to the right person at the right moment without any manual list-building.

Which 7 Klaviyo Flows Should Every Shopify Store Set Up First?

Every Shopify store, regardless of size or industry, should prioritise these seven Klaviyo automated flows. We have ordered them by typical build priority, so if you can only launch a few at once, start from the top.

1. Welcome Series

The welcome series triggers when someone joins your list, usually through a pop-up or footer sign-up form. This is the first flow most Shopify stores should build, because it sets the tone for the entire customer relationship while interest is highest.

• Trigger: New subscriber added to list
• Typical length: 3 to 5 emails over 5 to 7 days
• Goal: Introduce the brand, deliver any sign-up discount, and drive a first purchase

2. Abandoned Cart (Started Checkout) Flow

This flow recovers customers who added products to their cart or began checkout but did not complete the order. It is consistently one of the highest-converting flows on the platform.

• Trigger: Started Checkout or Added to Cart event without a completed order
• Typical length: 3 emails, starting 1 to 4 hours after abandonment
• Note: Turn off Shopify’s native abandoned checkout emails once this flow is live, so customers are not messaged twice

3. Browse Abandonment Flow

Browse abandonment targets visitors who viewed products but never added anything to their cart. It sits earlier in the funnel than cart recovery and helps recapture interest before it fades.

• Trigger: Viewed Product event with no subsequent Added to Cart
• Typical length: 1 to 2 emails within 24 hours
• Goal: Re-engage window shoppers with the exact products they viewed

4. Post-Purchase Flow

What happens after someone buys matters just as much as what happens before. This flow builds loyalty, sets shipping expectations, and opens the door to repeat purchases.

• Trigger: Order placed
• Typical length: 2 to 4 emails covering confirmation, shipping updates, and a follow-up review or cross-sell request
• Goal: Reduce “where is my order” support tickets and encourage a second purchase

5. Win-Back (Sunset) Flow

One of the most overlooked flows, this one re-engages customers or subscribers who have gone quiet, and protects your sender reputation by removing consistently unengaged contacts.

• Trigger: No opens or clicks in 90 to 120 days
• Typical length: 2 to 3 emails, ending with a list-cleaning suppression step
• Goal: Win back lapsed customers and safeguard deliverability

6. VIP / Customer Loyalty Flow

This flow identifies and rewards your highest-value customers, based on total spend or order frequency, to strengthen retention among the segment that matters most to lifetime value.

• Trigger: Customer crosses a spend or order-count threshold
• Typical length: 1 to 2 emails plus ongoing segment-based campaigns
• Goal: Increase repeat purchase rate among top customers

7. Back-in-Stock Flow

For Shopify stores that regularly sell out of popular products, this flow captures demand that would otherwise be lost and converts it the moment inventory is replenished.

• Trigger: Customer requests notification on a sold-out product page, then that product is restocked
• Typical length: 1 email, sent immediately on restock
• Goal: Recover otherwise-lost sales from out-of-stock demand

How Much Revenue Can Klaviyo Flows Generate for a Shopify Store?

Automated flows typically account for roughly a quarter to a third of total email-attributed revenue, despite making up only a small percentage of total emails sent. The table below summarises the benchmark figures most commonly cited in 2026 industry reports.

These figures vary by industry and list size, and should be treated as directional benchmarks rather than guarantees for any individual Shopify store. The consistent theme across every major 2026 benchmark report, from Klaviyo, Omnisend, and Litmus, is that flows outperform campaigns on a per-email basis by a wide margin.

For example, if you run a Shopify fashion store in India with a growing subscriber list and no flows currently active, building just the welcome and abandoned cart flows first would typically be enough to start recovering revenue that is currently being lost to unengaged sign-ups and incomplete checkouts, often within the first month of going live.

How Do You Set Up Klaviyo Flows on Shopify?

1. Install the Klaviyo app from the Shopify App Store and connect your store account.
2. Enable onsite tracking in the Klaviyo Shopify integration settings so behavioural events like Viewed Product and Added to Cart sync correctly.
3. Turn off Shopify’s native abandoned checkout emails to prevent duplicate messaging once your Klaviyo abandoned cart flow is active.
4. Build flows in priority order, starting with welcome and abandoned cart, then layering in browse abandonment, post-purchase, win-back, VIP, and back-in-stock.
5. Set clear trigger and timing rules for each flow, and split test send timing where the data suggests it (for example, testing a 1-hour versus 4-hour delay on the first abandoned cart email).
6. Review flow performance monthly, checking open rates, click rates, and revenue per recipient for each flow individually.
7. Refresh creative quarterly so returning subscribers do not see the same static emails indefinitely.

Common Mistakes Shopify Stores Make With Klaviyo Flows

• Leaving Shopify’s native abandoned checkout emails switched on, which causes customers to receive two competing recovery emails
• Building every flow at once instead of prioritising the two or three with the highest revenue impact first
• Never reviewing flow performance, so a flow that is underperforming keeps running unchanged for months
• Ignoring the sunset flow, which lets disengaged contacts quietly drag down deliverability for the whole account
• Treating flows as “set and forget” rather than a living system that needs quarterly creative and offer updates

Klaviyo Email Flows: Key Facts at a Glance

Where Klaviyo Flows Fit Into Your Wider Shopify Marketing Strategy

Klaviyo automated flows work best as one part of a connected system, not an isolated tactic. Traffic from Shopify SEO services and organic search fills the top of your list with new subscribers for the welcome flow to convert. A Shopify Facebook ads agency campaign or Shopify Google Ads management program drives paid traffic that browse abandonment and cart recovery flows can then win back. And once a customer buys, post-purchase and VIP flows keep them engaged long after the ad spend has stopped working. Store owners who treat Shopify email marketing as connected to SEO and paid acquisition, rather than a separate silo, consistently get more out of every dollar spent driving traffic to the store.
