Klaviyo Email Marketing Agency
for Shopify Revenue Growth
Managed Klaviyo email marketing for Shopify stores that want more revenue from flows, campaigns, segmentation, and retention – not just more emails sent.
Klaviyo Email Marketing Problems That Cost Revenue
Most Klaviyo accounts do not fail because the platform is weak. They fail because flows, campaigns, segmentation, and reporting are not managed with enough depth.
Live, but not improving
Flows keep running, but timing, logic, and performance are not reviewed.
Sent, but not planned
Emails go out, but audience logic, message, and KPI are often unclear.
Too broad to convert
VIPs, new buyers, lapsed customers, and cold leads receive similar messages.
Looks fine, hides gaps
Revenue can look healthy while RPR, CTOR, and repeat purchases underperform.
Metrics do not guide action
Reports show numbers, but not what should change next.
Better Metrics. Better Decisions. Better Revenue.
We use performance data to show what revenue email actually drives, where the account leaks value, and what should be improved next.
What We Actually Do As A Klaviyo Email Marketing Agency
We manage the full Klaviyo lifecycle for Shopify and ecommerce brands: flow optimisation, campaign management, segmentation, deliverability, email design, SMS coordination, reporting, and revenue attribution. Stores that still need clean data sync can start with our Klaviyo Shopify setup.
Klaviyo Flows
We audit, rebuild, and optimise Welcome Series, Abandoned Cart Flow, Browse Abandonment Flow, Post-Purchase Flow, Win-Back Flow, Sunset Flow, Replenishment Flow, Back-in-Stock Flow, Price Drop Flow, Review Request Flow, VIP Welcome Flow, and Subscription Renewal flows.
Campaign Management
We manage Klaviyo campaigns around product launches, seasonal demand, promotions, customer loyalty, retention goals, and lifecycle moments.
Segmentation
We build and maintain segments across customer lifecycle, purchase behaviour, email engagement, predicted value, and retention risk.
Reporting & Attribution
We review attributed revenue, revenue per recipient, flow revenue, campaign revenue, CTOR, conversion rates, list growth, unsubscribe rate, bounce rate, complaint rate, deliverability health, and customer lifetime value.
The goal is not to report inflated wins. The goal is to show what revenue email actually drives and what needs work next. If email traffic lands on slow or weak pages, we can connect this work with a Shopify speed audit, CRO audit, and conversion rate optimisation.
Benefits From Our Klaviyo Email Marketing Experts
We help Shopify and ecommerce brands get more value from the Klaviyo account, customer data, and subscriber base they already have.
Improve Flow Revenue
We optimise lifecycle flows so they do more than run in the background. We review logic, performance, timing, messaging, and conversion signals.
Strengthen Campaign Performance
We plan campaigns around segments, not guesswork. Each campaign has a defined audience, offer, subject line, preview text, CTA, exclusion logic, and KPI.
Improve Retention and Repeat Purchases
We help brands nurture customers after the first order, increase repeat purchases, recover abandoned carts, support product education, and use lifecycle messages to build stronger retention.
Make Klaviyo Easier To Manage
We give your Klaviyo account structure, reporting, campaign planning, and ongoing optimisation so the channel does not depend on last-minute decisions.

What Brands Say about Skalum
When Should You Hire a Klaviyo Email Marketing Agency?
A Klaviyo email marketing agency makes sense when your Shopify brand already uses Klaviyo, but email revenue feels lower than it should. Basic campaigns can be handled in-house. Strong Klaviyo performance needs deeper work across flow logic, segmentation, campaign planning, copy, design, deliverability, SMS coordination, attribution, and reporting.
You may need a Klaviyo email marketing agency if:
- your brand already uses Klaviyo, but revenue from email feels lower than it should
- you need expert Klaviyo campaign management
- you want a full-service Klaviyo agency instead of managing the channel in-house
- your flows are live, but no one has reviewed them in months
- your campaigns lack strong segmentation
- you want better retention, customer loyalty, and repeat purchases
- you need email and SMS coordination
- you want clearer reporting on ROI, revenue, conversion rates, and lifecycle performance
- you need a professional Klaviyo audit before making changes
- you want guidance from Klaviyo experts who understand Shopify data

More DetailsFrequently Asked Questions
A Klaviyo email marketing agency manages your Klaviyo account as an ongoing revenue channel. This can include flow optimisation, campaign strategy, email templates, segmentation, deliverability, email and SMS coordination, reporting, and lifecycle marketing. The goal is to improve retention, repeat purchases, conversion rates, customer loyalty, and email-attributed revenue.
The best Klaviyo agency should show platform expertise, not just email marketing advice. Look for deep knowledge of flows, segmentation, campaign management, deliverability, attribution, RPR, CTOR, compliance, email design, and Shopify integration. A strong agency should start with a Klaviyo audit, identify performance gaps, and build a data-driven strategy around your business goals.
Yes, this service is structured as full-service Klaviyo management. We support strategy, flows, campaign execution, email templates, segmentation, optimisation, reporting, deliverability, and email and SMS coordination. The retainer is built for brands that want Klaviyo managed as a long-term growth and retention channel, not as a one-off setup task.
Yes, if your in-house team does not have the time or expertise to manage Klaviyo at depth. In-house teams often handle basic campaigns, but deeper optimisation needs flow analysis, segmentation updates, deliverability checks, subject line testing, lifecycle strategy, email design, reporting, and revenue attribution. A Klaviyo agency can work with your team or fully own the channel.
Klaviyo campaign management includes campaign planning, audience segmentation, subject lines, preview text, email copy, email design, CTAs, testing, scheduling, exclusion logic, UTM tracking, reporting, and next-step recommendations. Campaigns can support product launches, promotions, customer nurture, loyalty, review requests, seasonal sales, and retention goals.
We improve Klaviyo flows by reviewing trigger logic, conditional splits, time delays, audience rules, message sequence, email design, CTA structure, discount use, product blocks, and flow metrics. We track flow revenue, RPR, CTOR, conversion rates, unsubscribe rate, and customer behaviour. Then we optimise based on what the data shows.
Yes, we can manage email and SMS in Klaviyo when SMS is part of your strategy. We align both channels around consent, lifecycle stage, audience, message priority, and customer journey. This prevents over-messaging and helps use SMS marketing for the right moments, such as cart recovery, VIP access, back-in-stock alerts, and urgent offers.
A Klaviyo audit reviews your account setup, flows, campaigns, segmentation, deliverability, attribution, email templates, compliance basics, and key metrics. We look for revenue leaks, weak logic, low-performing segments, deliverability risks, and reporting gaps. The output is a clear set of priorities, not a vague list of problems.
Early improvements can appear within 2-4 weeks after flow, segmentation, and deliverability fixes. Stronger revenue gains usually take 60-90 days because the account needs enough campaign data, testing cycles, and customer behaviour signals. If deliverability is damaged, sender reputation recovery may take longer.
Yes. Klaviyo can support customer loyalty through post-purchase flows, review requests, VIP segments, loyalty scheme emails, replenishment reminders, product education, win-back campaigns, and personalised offers. A strong lifecycle strategy helps customers buy again, not just complete their first order.
Yes. Skalum works with UK and international Shopify brands. If you are looking for a Klaviyo agency London partner or UK Klaviyo experts, we can support your account remotely with strategy, campaign management, flow optimisation, reporting, and ongoing Klaviyo guidance.
