Klaviyo Experts for Shopify Stores

Klaviyo experts look after the customer-data and messaging layer of a Shopify store. Klaviyo now calls itself an autonomous B2C CRM: it unifies data from Shopify and 350+ other apps, then automates email, SMS, WhatsApp, RCS and mobile push, with service tools such as Customer Hub and Customer Agent alongside. Merchants hire for the jobs that sit between the two systems. Onsite tracking that actually fires. Flows triggered by real Shopify behaviour. Consent that syncs the right way. Segments built on profile data the next sync won't overwrite. Others need flows and lists moved across from another email platform, or tracking wired into a headless storefront. The Klaviyo badge is on 44 shopexperts profiles as of October 2026 — 23 agencies and 21 freelancers, with the biggest groups in the US, Canada and the UK.

Shopify stores that earn their keep. I run Graftstudio, the technical and commercial lead for mid-market DTC brands on Shopify Plus. Brands bring me in when the store has outgrown the people who set it up. I find what it's costing, fix what the numbers say pays, and measure every change. In 15+ years I have partnered with over 160 brands that generate £80m in sales across their stores. Cult Gaia, Victoria Beckham, Gymshark, Seafolly and Ireland's largest salon group among them. I'm a Shopify Plus Partner, and three in four brands come back. I take on a small number of brands at a time, offering audits, fix sprints and fractional store ownership.

Shopify Plus EngineerLondon, United KingdomFrom $40

I'm Phil, founder of Candystore Studio, a Shopify studio. I've spent over 12 years building for the web and the last 6 on Shopify, including work for brands such as BrewDog, Hoodrich, Ooni and Vuse UK. Most of my work now is keeping Shopify stores working, secure and lean as brands do more themselves with AI tools and native Shopify features. Building a section with Sidekick or ChatGPT takes an afternoon. What takes the time is everything after: code that breaks on the next theme update, apps nobody remembers installing, scripts left behind by old apps, tracking that quietly stops. That is the part I take off your plate. In practice that means auditing what is installed and who has access, repairing and documenting AI-generated code, replacing single-job apps with native Shopify features or clean theme code, and monthly care for brands that want an expert watching the store. My core stack is Liquid and Online Store 2.0, JavaScript and TypeScript, and I work regularly with Klaviyo, Recharge, Rebuy, Algolia and Judge.me. When a project needs design or branding, Candystore's design team works alongside me. Every engagement starts with a fixed-price review and a written report you can act on with me or anyone else. Work happens on a duplicate theme and goes live only after your sign-off.

Rising Commerce is a Shopify practice led by David Martel, a Shopify Partner since February 2017. Dave has spent more than ten years on the platform, across theme development, app integrations, migrations, performance, and the fixes that keep a live store selling. We help merchants turn a Shopify store into a faster, clearer, easier business to run. The work covers new builds and redesigns, theme customization, migrations onto Shopify, site speed, and ongoing care. Most of that work is in clothing and fashion, food and drink, health and beauty, and jewelry. You work directly with Dave. The published response time is 30 minutes, and clients on both Shopify Partners and Shopexperts describe the same pattern: a clear reply, a careful fix, and someone who is still there the next time something breaks.

What a Klaviyo expert actually does on Shopify

Most Klaviyo problems on Shopify aren't copy problems. They're data problems: an event that never reaches Klaviyo, a consent status that didn't sync, a segment built on a property Shopify keeps replacing. A good expert fixes the plumbing first, then builds on it.

Setup and tracking. Connecting the store, switching on the Klaviyo theme app embed and confirming onsite tracking in Klaviyo's own settings. Then checking that Viewed Product, Viewed Collection, Submitted Search, Added to Cart and Active on Site all arrive, and syncing the catalogue, including Shopify Markets for stores selling in more than one country.

Flow architecture. Browse, cart, welcome and post-purchase flows triggered by real Shopify events, plus AI-powered segments and flow triggers built from historical and real-time data. Composer, Klaviyo's AI campaign builder, will assemble an on-brand campaign across channels. Someone still has to decide who should receive it.

Migration. Moving lists, flows, templates and consent records from another email or SMS platform, then rebuilding the logic around Klaviyo's Shopify events rather than copying old flows step by step.

Channels and consent. SMS, WhatsApp, mobile push and sign-up forms, plus consent app blocks on the thank-you and order status pages, and on checkout for Shopify Plus stores.

Integrations and headless. Sending events in from Shopify Flow, connecting other apps to Klaviyo profiles, and adding the hand-written onsite snippets a Hydrogen storefront needs.

Service tools. If you plan to run support inside Klaviyo through its helpdesk, Customer Hub or Customer Agent, ask directly whether the expert has configured them. It's a different skill from flow building.

How much does a Klaviyo expert cost?

All 44 Klaviyo-badge experts on shopexperts list a starting price on their profile. We pulled them in October 2026, in US dollars, ignoring any profile set to zero. A starting price is the floor of an expert's pricing across all their work, not an estimate for your Klaviyo job.

Experts who only start at bigger scopes

Klaviyo quotes move with the number of systems involved, not the number of emails. Adding SMS or WhatsApp brings consent work. A headless storefront brings manual tracking code. Pulling profile data from several other apps means mapping fields before anyone builds a flow.

For a quote you can compare, send your Shopify plan (Plus or not), whether the theme is Online Store 2.0 or headless, the flows running today, the channels you want and any platform you're leaving. Screenshots of your current flow list shorten the first call. The Klaviyo cost guide covers the subscription, which sits on top of any expert fee.

Klaviyo Shopify setup: tracking, consent and Flow details

Two tracking routes, not one. Klaviyo records Active on Site and Viewed Product through its theme app embed, while Viewed Collection, Submitted Search and Added to Cart arrive through the Shopify pixel in customer events. When a browse or cart flow goes quiet, an expert checks both routes before touching the flow.

The Flow connector shrank. Klaviyo retired the "Create a campaign" action in Shopify Flow on 16 October 2025. "Track an event" is the only action left, so any workflow that built campaigns from Flow has to become an event that triggers a Klaviyo flow.

Synced properties get replaced. Custom profile properties that come from Shopify, customer tags included, are overwritten on the next sync if someone edits them in Klaviyo. Changes belong in Shopify.

SMS consent syncs once. Consent collected in Shopify only reaches Klaviyo when the person subscribes to SMS for the first time. Anyone re-subscribing won't sync that way, so an expert audits consent sources before a large SMS send.

Checkout consent needs Plus. The SMS and WhatsApp consent app block works on thank-you and order status pages on every plan. Only Shopify Plus stores can place it on the checkout page.

Headless has two halves. On Hydrogen, the native integration syncs orders, catalogue and subscribers. Onsite tracking still needs code snippets added by hand.

Briefs go stale. Klaviyo Starter in Shopify now sets up a sign-up form, welcome email and abandoned checkout automation without leaving the Shopify admin, and only the store owner can run it. Klaviyo also sells helpdesk, Customer Hub, Customer Agent and Reviews, so a brief that treats it as an email tool alone is out of date.

Klaviyo work by service category

Klaviyo-badge experts each list several service categories on shopexperts. The counts show where this group leans: more builders than pure campaign writers.

Store setup and management

34 of 44 list it, the category for account connection, app embed and catalogue sync

Shopify development

33 of 44 list it, covering Hydrogen snippets, Flow events and app data feeds

Marketing and growth

19 list it, where flow strategy, AI-powered segments and Composer campaigns sit

16 list it, for email templates, sign-up forms and pop-ups

Consulting and strategy

14 list it, useful for planning email, SMS, WhatsApp and push together

AI and emerging tech

10 list it; ask this group about Customer Agent and AI-driven segments

Klaviyo experts: questions on partners, Flow and consent

Are the experts listed here Klaviyo partners?

Not necessarily. The badge shows that an expert offers Klaviyo work on their shopexperts profile. It isn't Klaviyo partner status. Klaviyo runs its own programme, K:Partners, for agency and solution partners, and its Agency Partner Directory displays level labels such as Platinum Master and Klaviyo Partner. If partner status matters to you, ask for the expert's directory listing and check it yourself.

Should a Klaviyo agency or a freelancer run my email and SMS?

This group splits almost evenly, 23 agencies and 21 freelancers. A freelancer usually fits a defined job such as fixing tracking, rebuilding one flow or adding consent blocks. Pick an agency when email, SMS and WhatsApp run as one programme with weekly campaigns, or when a migration involves dozens of flows and segments. Hire the smallest team that covers your real scope.

Does a headless or Flow-heavy store need a Klaviyo developer?

Usually, yes. Hydrogen and other headless storefronts need onsite tracking snippets added by hand. Custom events sent through the Shopify Flow "Track an event" action need fields mapped, and apps feeding profile data need checking. Copy, segments and send schedules stay marketing work. Of the 44 badge experts, 33 list Shopify development, so a developer isn't hard to find here.

Why did my Shopify Flow workflow stop creating Klaviyo campaigns?

Klaviyo retired the "Create a campaign" action for Shopify Flow on 16 October 2025, so any workflow built on it stopped doing its job. The remaining action, "Track an event", sends data from the workflow into Klaviyo. The fix is to have Flow track an event and let a Klaviyo flow or segment respond. Our guide to Klaviyo flows on Shopify covers the triggers.

Why do customer tags I edit in Klaviyo keep changing back?

Custom profile properties that Klaviyo receives from Shopify, customer tags included, are overwritten on the next sync, and Klaviyo advises against editing them on its side. Make the change in Shopify and let it flow through, or keep anything you want to manage in Klaviyo in a separate property. An expert building segments should know this before relying on synced tags.

Can Klaviyo collect SMS consent at checkout?

Only on Shopify Plus. Klaviyo's consent app block collects transactional and marketing consent for SMS and WhatsApp on the thank-you and order status pages on any plan, but the checkout page itself is limited to Plus. Separately, SMS consent captured in Shopify only syncs to Klaviyo for first-time SMS subscribers, so ask how returning subscribers will be handled.
