Netalico is a Shopify agency that also runs Klaviyo email and SMS. It is a Shopify Plus Premier Partner and a Klaviyo Gold Partner, and the same in-house team that builds and maintains a brand's Shopify store also designs, builds, and runs its Klaviyo flows and campaigns. That setup suits mid-market and enterprise DTC brands, roughly $2M to $50M in GMV, whose email program depends on Shopify data that an email-only agency cannot change.
Below is why brands look for one agency to cover both, what to check before hiring one, and when two separate specialists is the better choice.
Why brands want one agency for Shopify and Klaviyo
Most brands start with two vendors: a development agency for the store and an email agency or freelancer for Klaviyo. It works until the two halves need to talk to each other, and on a growing Shopify store they need to constantly.
A few examples of problems that sit exactly on the seam:
- The abandoned cart flow barely sends because the theme is not passing cart events to Klaviyo.
- Product recommendations in emails show sold-out items because the catalog feed has drifted.
- Subscription customers get first-purchase discounts because subscription data never reached their Klaviyo profile.
- A new signup popup lifts list growth but slows the site enough to hurt conversion.
Each one needs a developer to fix and an email marketer to notice. With two vendors, the email team files a ticket, the development team prioritizes other work, and the problem lasts a quarter. With one team, it is fixed in the same week by the people who found it.
What to look for in a Shopify agency that runs Klaviyo
Plenty of Shopify agencies list email marketing as a service. Fewer run it as a real practice. Check these.
Partner status on both platforms. Shopify's partner tiers and Klaviyo's partner tiers are both earned. Netalico is a Shopify Plus Premier Partner, one of the two highest tiers in Shopify's partner program, and a Klaviyo Gold Partner.
Published or clearly scoped pricing. You should know what an audit, a flow build, and monthly campaign management cost before the first call. Netalico's are published: a $1,000 Klaviyo audit, flow packages from $2,500 to $6,000, and campaign management from $1,200 to $5,000 per month.
Klaviyo results they can name. Ask for a client, a starting point, and an outcome. Ours: Milestones by Ashleigh Bergman grew email from 3% of site revenue to 44.7%, and from $13K in email revenue in 2019 to more than $2.2M in 2024. The Milestones case study shows what we built.
Development depth on the same team. Ask who writes custom events, maintains the catalog feed, and connects subscription and loyalty apps. If the answer is "your developer," you still have two vendors.
Campaigns as well as flows. Some agencies build flows and leave. If you want ongoing sends, confirm they plan, design, and send campaigns monthly.
Ownership. Everything built in your Klaviyo account and your Shopify store should belong to you if you leave.
Questions to ask on the first call
- Who on your team builds Klaviyo flows, and who writes Shopify code? Are they employees?
- How do you get custom events and app data into Klaviyo?
- Can you show a flow you rebuilt and what changed afterward?
- How do you handle SMS consent and state compliance?
- What does a migration from our current platform involve? (See our guide to migrating from Mailchimp to Klaviyo.)
- What do you report on each month, and is it tied to revenue?
When two specialists is the better choice
One agency is not always right. If your store is simple, your Shopify data is clean, and what you need is high-volume creative and daily sends, a dedicated email agency may give you more creative capacity per dollar. If your store needs a major rebuild and email is a minor channel, start with the store.
The single-agency model pays off when email and SMS are a top revenue channel and the store behind them is complex: Shopify Plus, subscriptions, loyalty, B2B, or several storefronts.
How Netalico runs it
Netalico was founded in 2013 and has been a Shopify Partner since 2016, with hundreds of Shopify builds behind it. Everyone is in-house and nothing is subcontracted: the team is Americas-based, with hubs in New York, Los Angeles, San Francisco, and Miami plus colleagues in Canada and Brazil, all overlapping the US business day.
Klaviyo clients include Oatly, Milestones by Ashleigh Bergman, Silverist, and VYBES. For Oatly, we moved order, shipping, and subscription emails that were scattered across Shopify, AfterShip, and Recharge into Klaviyo, then built the welcome, browse abandonment, and back-in-stock flows on top.
Frequently asked questions
Is there a Shopify agency that also does Klaviyo?
Yes. Netalico is a Shopify Plus Premier Partner and a Klaviyo Gold Partner, and one in-house team handles both the Shopify store and the Klaviyo email and SMS program.
Is it better to use one agency for Shopify and email?
It usually is when email and SMS drive a large share of revenue and the store is complex, because most Klaviyo problems on Shopify Plus are data problems that need a developer. For simple stores that mainly need creative volume, a dedicated email agency can be a good fit.
How much does it cost to have an agency run Klaviyo?
At Netalico, a Klaviyo audit is $1,000, flow packages run $2,500 to $6,000 one time, and campaign management runs $1,200 to $5,000 per month. Our Klaviyo agency pricing guide explains what changes the number.
Can one agency handle both email and SMS in Klaviyo?
Yes. Klaviyo runs email and SMS on the same customer profiles, so one team can plan them together and handle the consent and compliance side as well.
