Klaviyo Flows Every Shopify Subscription Brand Should Build

The best Shopify subscription brands do not just send order confirmations. They use Klaviyo flows to welcome new subscribers, remind them before each order, recover failed payments, respond when someone pauses or skips, celebrate loyalty and win people back after they cancel. This guide covers the flows worth building, in the order we build them.

Quick Answer

Keep your core ecommerce flows in place, because the welcome series and abandoned cart and checkout flows are normally our clients' best performers by revenue and conversion. Then add subscription flows in this order: a subscription welcome journey, an upcoming order reminder, failed payment recovery and a win back journey, followed by pause and skip follow ups, milestones, anniversary upsells and an at risk check in. Measure them on churn, recovery and lifetime value rather than open rates.

Key Takeaways

• Across our Klaviyo clients, the welcome series and the abandoned cart and checkout flows are normally the best performing flows by total revenue and conversion rate.
• Klaviyo's benchmarks show flows earning about 41% of email revenue from 5.3% of sends.
• Subscription flows respond to what subscribers do, so check which events your subscription app sends to Klaviyo.
• Failed payments cause about a third of ecommerce churn in Recurly's benchmarks, which makes recovery an early priority.
• Recurly found that three in four subscribers who pause come back, so pause follow ups are worth building.
• New UK rules due in January 2027 will require regular reminders and easier cancellation.

Start with the Flows That Already Perform

Before building anything subscription specific, make sure the foundations work. Across our Klaviyo clients, the welcome series and the abandoned cart and checkout flows are normally the best performing flows by total revenue and conversion rate. For a subscription brand, those flows still matter: the welcome series turns new sign ups into first subscribers, and abandoned checkout flows recover people who started a subscription and did not finish.

Flows earn their keep across the board. Klaviyo's benchmarks, drawn from more than 183,000 brands, show flows generating about 41% of email revenue from just 5.3% of sends, with 18 times the revenue per recipient of campaigns. Our guide to optimising your Shopify email marketing covers the core flows in detail.

How Subscription Email Is Different

Standard ecommerce email aims to win the next purchase. A subscriber has already agreed to buy again, so the job changes: keep them subscribed, help them get value from the product and prevent avoidable cancellations. That makes lifecycle flows, triggered by what subscribers actually do, more important than promotional campaigns. Subscribers receive emails because they did something, such as pausing, skipping or hitting a payment problem, which makes those emails feel helpful rather than salesy.

The Subscriber Lifecycle Map

We plan subscription flows around where each subscriber is in their relationship with the brand, rather than around a campaign calendar.

The Data Behind Subscription Flows

Subscription flows depend on events: a subscription starting, an upcoming charge, a failed payment, a pause, a skip, a product swap, a cancellation and the reason given for it. The richer the events your subscription app sends to Klaviyo, the more precisely you can respond.

Recharge has a long established Klaviyo integration that passes subscription events into Klaviyo. If you use Shopify Subscriptions, check which subscription events reach Klaviyo before you plan flows that depend on them. Many of the flows below can be built either way, so do not delay lifecycle marketing while you decide. Our guides to Recharge vs Shopify Subscriptions and the best Shopify subscription apps compare the options.

Our Recommended Build Order

Building every flow at once usually leaves a collection of half finished automations. Build in stages, measure, refine and then expand:

Flow 1: Subscription Welcome Journey

This is the most important subscription flow. The customer has already decided to buy, so the goal is reassurance: confirm the decision, explain what happens next and show them how to manage their subscription. Many early cancellations come from uncertainty rather than dissatisfaction, such as not knowing when they will be charged or how to skip a delivery. We usually recommend four or five emails over the first month:

Keep the tone reassuring rather than promotional. None of these emails needs to sell another product.

Flow 2: Upcoming Order Reminder

Subscribers rarely cancel because they were reminded about a payment; they cancel because they were surprised by one. Send the reminder three to five days before each charge, with the date, the amount, the products included, the expected dispatch date and a clear link to skip, swap, pause or update payment details. Keep it informative and simple.

This flow is also becoming a legal expectation. The UK government announced on 9 August 2026 that new subscription rules due in January 2027 will require clearer upfront information, regular reminders, easier cancellation and a 14 day cooling off period after a trial or a long term contract renewal.

Flow 3: Failed Payment Recovery

Not every lost subscriber chose to leave. Expired cards, replacement cards and bank declines all cause involuntary churn, and it is often the easiest churn to prevent. In Recurly's July 2026 ecommerce benchmarks, involuntary churn was 1.38 points of a 4.25% total, about a third. Recurly labels those figures annual, although its own worked example treats a similar rate as monthly, so use the shape rather than the level.

We recommend three emails: an immediate notice with a single button to update payment details, a friendly reminder a few days later, and a final notice before the subscription would be cancelled. Keep the language calm; most failures are accidents, not decisions.

Flow 4: Pause Follow Up

A pause is a positive signal: the subscriber chose not to cancel. Recurly's 2026 State of Subscriptions report found that where merchants offered a pause before cancellation, pause usage rose by 337%, and three in four paused subscribers returned. Confirm the pause straight away and explain how to resume, check in a week or two later with a reminder of the subscription's benefits, and, if it suits your brand, offer a small thank you near the end of the pause. Support, not pressure, is the tone to aim for.

Flow 5: Skipped Order Follow Up

A skip is a soft signal that engagement may be dipping, not a cancellation. One email is usually enough: confirm the skip, show the next delivery date, link to the subscription portal and, where it fits, suggest a swap for someone who may simply want something different. Avoid discount led win back messages here; they make subscribers feel pressured every time they adjust their order.

Flow 6: Product Swap Confirmation

A swap is one of the healthiest signals a subscriber can send, because they are shaping the subscription to suit them rather than leaving. Confirm the change, summarise the new order and delivery date, add guidance on the new product and remind them they can adjust their subscription any time. The more visible swaps are, the more subscribers see an alternative to cancelling.

Flow 7: Milestone Celebrations

At three, six and twelve months, thank subscribers for their loyalty. Show how long they have subscribed, how many deliveries they have received, what they have saved and any rewards they have earned. For bigger milestones, consider early access, a gift with the next order or bonus loyalty points rather than a discount. Recognition builds an emotional connection that automated billing alone never will.

Flow 8: Win Back Journey

Some cancellations are simply right for the customer, so respect the decision and keep the door open. Acknowledge the cancellation straight away, remind them of what they valued after a week or two, and invite them back around a month later, with an incentive only if it suits the reason they left. Use cancellation reasons to tailor the message:

Under the coming UK rules, cancelling must stay easy. Win back emails should follow a cancellation, never obstruct one.

Flow 9: Anniversary and Upsell

Long term subscribers already trust your products, which makes an anniversary a natural moment for relevant recommendations. Lead with recognition, then reflect on the products they have enjoyed and their savings, offer a reward, and only then suggest complementary products or an upgrade that genuinely improves their experience.

Flow 10: At Risk Check In

Most subscribers drift before they cancel: repeated skips, a lower delivery frequency, failed payments, support questions about cancelling, or no engagement with your emails. Build Klaviyo segments from those signals and start a supportive check in: ask if everything is working, remind them of the benefits, and explain options such as pausing, swapping or changing frequency. Klaviyo's predictive analytics, including churn risk, need at least 500 customers with orders, 180 days of order history including orders in the last 30 days, and some customers with three or more orders, so smaller brands should rely on behavioural signals instead.

How to Measure Your Flows

Open rates rarely tell you whether a subscription programme is getting healthier. Give each flow a commercial measure:

Track monthly recurring revenue, subscriber growth, churn, payment recovery and revenue per recipient on one dashboard, review flows every quarter and audit the whole lifecycle once a year. Our guide to Shopify subscription metrics explains how to calculate them. The most common mistakes we see are treating subscribers like one time buyers, only emailing when selling, ignoring behavioural events, sending the same win back email to everyone and never revisiting flows once they are live.

Why Matters Perspective

The brands that retain subscribers best are not the ones with the most flows. They are the ones that respond to each subscriber action with something genuinely helpful, and keep improving those responses. Across our Klaviyo clients, the welcome series and the abandoned cart and checkout flows are normally the best performing flows by total revenue and conversion rate. That is why we check the foundations before building anything new: a subscription programme built on a weak welcome series and missing abandoned checkout flows loses people before they ever subscribe.

We usually build on Shopify, Recharge and Klaviyo, because that combination gives subscription brands rich events and flexible automation, but the strategy matters more than the stack. We are a Klaviyo and Recharge partner, and our Shopify subscriptions service covers how we set these flows up for clients.

Frequently Asked Questions

How many Klaviyo flows does a subscription brand need?

Start with the foundations, a welcome series and abandoned cart and checkout flows, plus four subscription flows: a subscription welcome journey, an upcoming order reminder, failed payment recovery and a win back journey. Add pause and skip follow ups, milestones, anniversary upsells and an at risk check in once those perform well.

Which subscription flow should I build first?

The subscription welcome journey. The first weeks shape long term retention, and explaining billing, delivery and how to manage the subscription prevents many avoidable cancellations.

What are the best performing Klaviyo flows?

Across our Klaviyo clients, the welcome series and the abandoned cart and checkout flows are normally the best performing flows by total revenue and conversion rate. Klaviyo's own benchmarks show flows generating about 41% of email revenue from 5.3% of sends.

Do I need Recharge for these Klaviyo flows?

No, but it helps. Recharge has a long established Klaviyo integration that passes subscription events such as upcoming charges and cancellations. With Shopify Subscriptions, check which subscription events reach Klaviyo before planning flows that depend on them.

How often should I review subscription flows?

Review each flow every quarter against its commercial measure, such as churn, payment recovery or reactivation, and audit the whole subscriber lifecycle once a year.

Can I use SMS for subscription flows?

Yes, for time sensitive messages such as failed payments, upcoming order reminders and delivery updates, with the subscriber's consent. Keep email as the main lifecycle channel and use SMS selectively.

Do UK rules affect subscription emails?

Yes. New UK rules announced on 9 August 2026 and due in January 2027 will require clearer upfront information, regular reminders and easier cancellation, so upcoming order reminders and simple cancellation matter even more.

Final Thoughts

Subscription lifecycle marketing exists to keep subscribers successful for longer. Keep your best performing foundation flows strong, then respond to every subscriber action, from the first order to a failed payment, a pause or a cancellation, with a message that helps. Measure each flow on retention rather than opens, and keep improving it.
