Shopify Klaviyo Agency
The Team That Builds Your Shopify Store Also Runs Your Klaviyo
Netalico is a Shopify Klaviyo agency for mid-market and enterprise DTC brands. We are a Shopify Plus Premier Partner and a Klaviyo Gold Partner, and the same in-house team that builds and maintains your Shopify store also designs, builds, and runs your Klaviyo email and SMS program.
That is the difference that matters. Most Klaviyo problems are not copywriting problems. They are data problems: events that never fire, a product feed that drifts out of sync, subscription and loyalty data that never reaches a profile. We fix those at the source because we own the source.
Talk to us about KlaviyoWhy Klaviyo Breaks When Two Vendors Own the Two Halves
Klaviyo is only as good as the data Shopify sends it. On a simple store that data flows on its own. On a Shopify Plus store with subscriptions, loyalty, B2B pricing, custom checkout logic, or several storefronts, it usually does not, and the email agency cannot see why.
The typical pattern: an email agency builds flows, the flows underperform, and the fix sits in the theme or an app integration that belongs to a different vendor. The email agency files a ticket, the development agency deprioritizes it, and the abandoned cart flow keeps sending the wrong products for another quarter.
When one team owns both halves, that loop disappears. Our Klaviyo work routinely includes:
- Custom events and properties pushed from the theme and apps, so flows can branch on real behavior instead of guesses.
- Catalog and feed integrity, so product blocks and recommendations show what is actually in stock at the right price.
- Subscription, loyalty, and review data (Recharge, loyalty programs, review apps) mapped onto Klaviyo profiles.
- Consolidated transactional email. For Oatly we moved order, shipping, and subscription messages that were scattered across Shopify, AfterShip, and Recharge into Klaviyo, so the brand could finally see the whole post-purchase journey in one profile.
- Forms and popups that do not slow the store, built and tested by the people responsible for your Core Web Vitals.
Results: Milestones Grew Email From 3% to 44.7% of Revenue
When Milestones by Ashleigh Bergman started working with us, email drove 3% of site revenue. We built the email capture, the full core flow set (welcome, abandoned cart, abandoned checkout, browse abandonment, post-purchase), a campaign testing plan, and launched SMS as a new channel. Ashleigh's team kept creative direction; we owned strategy, build, and testing.
Email grew from $13K in revenue in 2019 to more than $2.2M in 2024, and from 3% to 44.7% of total site revenue, making it Milestones' top sales channel. The full story is in our Milestones Klaviyo case study.
Other Klaviyo clients include Oatly, Silverist, and VYBES, alongside the Shopify builds we run for brands like Big Green Egg, Rifle Paper Co, and Feetures.

Klaviyo Audit
A Klaviyo audit for Shopify and Shopify Plus brands, done by the team that builds Shopify stores and runs Klaviyo programs every day. Netalico is a Klaviyo Gold Partner and a Shopify Plus Premier Partner. You get a prioritized plan, not a list of best practices.
What we check:
- Every live flow: triggers, filters, splits, timing, and revenue per recipient
- Missing flows that brands your size usually run (winback, VIP, back-in-stock, sunset)
- Segmentation and list hygiene
- Deliverability: authentication, engagement, and sending reputation
- Signup forms and popups, including their effect on site speed
- The Shopify data Klaviyo depends on: events, catalog feed, subscription and loyalty app integrations
Deliverables:
- Detailed audit report with prioritized recommendations
- Flow optimization and new flow suggestions
- List hygiene and segmentation improvements
- Deliverability analysis
- A walkthrough call with the team that wrote the report
Findings can roll straight into a flow package or monthly campaign management. See pricing and results on our Shopify Klaviyo agency page.
Choosing a Klaviyo Agency for Shopify
| Netalico | Email-only agency | Freelancer | In-house hire | |
|---|---|---|---|---|
| Shopify development | Same in-house team | Handed to your developer | Rarely | Depends on hiring |
| Custom events and data | Built at the source | Requested via tickets | Limited | Needs a developer |
| Flows and campaigns | Strategy, design, build, send | Strategy, design, build, send | Build only, usually | Yes, if staffed |
| Shopify Plus, B2B, subscriptions | Hundreds of Shopify builds | Varies | Rarely | Varies |
| Migrations to Klaviyo | Consent and suppression preserved | Usually | Risky | Risky |
| Published pricing | Yes, on this page | Sometimes | Hourly | Salary plus tools |
An email-only agency is a good fit when your Shopify data is clean and the job is creative and cadence. It struggles when the constraint is the store itself, which on Shopify Plus it often is.
What Klaviyo Clients Say
Chief Growth Officer, Cellphone Charging Company
Netalico has been great at helping us navigate and explain the difference between B2B and B2C marketing. They manage help desk integrations, email marketing integrations, and various customer journey integrations.
Jonathan Eppers | Founder & CEO, VYBES
Netalico took over our existing Shopify website to help us improve its performance and also helped us set up Klaviyo for emailing. They helped us build new features for the website, which required some design work to integrate them into the platform.
Evelyn Wang | Founder & CEO, Silverist
Netalico has delivered a functional website and set up email flows that make sense and are performing well. The team is honest and flexible, offering solutions that work for the client's business.
Why Netalico for Klaviyo
Netalico was founded in 2013 and has been a Shopify Partner since 2016. We are a Shopify Plus Premier Partner, the most selective tier, and a Klaviyo Gold Partner, with hundreds of Shopify builds behind us.
One team, both platforms. The people who build your theme, checkout extensions, and integrations are the people who build your flows, so data problems get fixed where they start.
Everyone is in-house and nothing is subcontracted. Netalico is an Americas-based agency with hubs in New York, Los Angeles, San Francisco, and Miami, plus colleagues in Canada and Brazil. The whole team overlaps the US business day.
Built for mid-market DTC. Most clients are brands doing $2M to $50M in GMV, usually on Shopify Plus, where email and SMS are a top-three revenue channel and a broken flow is expensive. If conversion on site is the bigger constraint, our Shopify CRO agency work pairs directly with Klaviyo.
FAQ
Klaviyo Agency: Frequently Asked Questions
What does a Klaviyo agency do?
A Klaviyo agency plans, builds, and optimizes a brand's email and SMS program inside Klaviyo: automated flows, campaigns, segmentation, signup forms, deliverability, and reporting. Netalico also handles the Shopify side, including custom events, catalog data, and app integrations that Klaviyo depends on.
How much does a Klaviyo agency cost?
At Netalico a Klaviyo audit is $1,000, automated flow packages run $2,500 to $6,000 one time, and monthly campaign management runs $1,200 to $5,000 per month depending on email and SMS volume. Klaviyo work can also run inside a Shopify retainer.
Is Netalico a Klaviyo partner?
Yes. Netalico is a Klaviyo Gold Partner and a Shopify Plus Premier Partner.
Should I hire a Klaviyo agency or build an in-house team?
An agency is usually faster and cheaper until email and SMS need a full-time strategist, designer, and developer. Many brands start with an agency to build the flows and foundation, then bring campaign sending in-house once the program is stable. We support both models.
Can you migrate us to Klaviyo from Mailchimp, Attentive, or Omnisend?
Yes. A migration moves subscribers with their consent status, suppression lists, and segments, then rebuilds flows natively in Klaviyo. We run the old and new platforms in parallel briefly so no automated message goes missing during the switch.
Do you run campaigns or only build flows?
Both. Flow packages are one-time builds, and campaign management plans are monthly, from 4 emails a month up to 16 emails and 4 SMS a month.
Do you work with Shopify Plus, B2B, and subscription stores?
Yes, and that is where our Shopify development background matters most. B2B pricing, multiple storefronts, and subscription apps all change what data reaches Klaviyo.
Can you audit a Klaviyo account you did not build?
Yes. Most engagements start that way. The Klaviyo audit reviews flows, segments, list health, deliverability, and integrations, and the findings can roll into a flow package or retainer.
