Hiring a Klaviyo email marketing agency sounds simple.
You find someone who can:
- Write emails.
- Design campaigns.
- Set up flows.
- Send newsletters.
- Maybe build a few segments.
But that’s where many Shopify brands make the mistake.
Because a good Klaviyo email marketing agency should do more than “make emails.”
They should understand how email fits into your Shopify customer journey.
That means they should know how to follow up with browsers, recover abandoned carts, support first-time buyers, bring past customers back, segment your audience, and report on what is actually working.
The real question is not:
Can this agency send emails?
The better question is:
Can this agency build an email system that supports our Shopify store’s growth?
That’s what this guide will help you answer.
Quick Answer: What Should a Klaviyo Email Marketing Agency Do?
A Klaviyo email marketing agency should help Shopify brands plan, build, manage, and improve email marketing inside Klaviyo.
Not just create email output.
A strong agency should help with strategy, flows, campaigns, segmentation, copy, design, reporting, and ongoing optimization.
Area | What It Means |
Klaviyo strategy | Creates the plan for flows, campaigns, segmentation, and reporting |
Email flows | Builds automated follow-up for key customer moments |
Campaigns | Plans regular sends around products, promos, launches, education, and retention |
Segmentation | Sends different messages to different customer groups |
Copywriting | Creates clear email messaging that supports the click and sale |
Email design | Builds mobile-friendly email layouts |
Reporting | Shows what worked, what didn’t, and what to improve |
Optimization | Improves flows and campaigns over time |
A good Klaviyo agency should improve email direction, not just email output.
Klaviyo has an official Service Partner Directory where brands can find partners for support, guidance, and services around Klaviyo.

But even when choosing from partner directories, you still need to know what to check before hiring.
Why Hiring a Klaviyo Agency Is Different From Hiring an Email Designer
An email designer can make emails look good.
That matters.
But email marketing is not only design.
A pretty email can still underperform if it goes to the wrong audience, at the wrong time, with the wrong message.
That’s why hiring a Klaviyo agency is different.
A Klaviyo agency should understand how email connects to the full customer journey.
If You Only Hire for Design | What May Be Missing |
Pretty campaign visuals | Weak segmentation |
Branded layouts | Poor email timing |
Nice templates | No customer journey strategy |
Polished graphics | No revenue reporting |
Good-looking emails | Weak offers or unclear CTA |
This does not mean design is unimportant.
It means design should support the strategy.
Your email should be easy to read, clear to click, and built around the customer’s next step.
Not just nice to look at.
What Should Be Included in Klaviyo Email Marketing Services?
Before hiring, you need to know what Klaviyo email marketing services should actually include.
Every agency will package services differently, but these are the key areas to check.
Service | Why It Matters |
Klaviyo audit | Finds leaks, gaps, and missed opportunities |
Shopify/Klaviyo setup check | Makes sure customer and order data are syncing properly |
Flow setup or optimization | Builds automated follow-up for key customer moments |
Campaign calendar | Keeps emails consistent and strategic |
Email copywriting | Turns customer moments into clear messaging |
Email design | Makes emails readable, branded, and mobile-friendly |
Segmentation | Sends more relevant emails to better-fit audiences |
A/B testing | Helps improve performance over time |
Reporting | Shows what’s working and where to improve |
Deliverability monitoring | Helps protect inbox placement and sender reputation |
If an agency only talks about campaigns, ask what happens to your flows.
If they only talk about design, ask how they handle segmentation.
If they only talk about setup, ask how they optimize after launch.
Because email marketing is not one task.
It is a system.
These are also the core areas we focus on in our email marketing services for ecommerce brands, especially for Shopify stores that need stronger flows, campaigns, segmentation, reporting, and optimization.

What Shopify Experience Should a Klaviyo Agency Have?
A Klaviyo agency does not need to only work with Shopify.
But if you’re a Shopify brand, they should understand Shopify customer behavior.
That means they should know how shoppers move through your store.
They should understand:
- Shopify customer data
- Product pages
- Product collections
- Product views
- Add-to-cart behavior
- Checkout behavior
- First-time buyers
- Repeat buyers
- Product launches
- Seasonal campaigns
- Retention opportunities
This matters because Klaviyo can connect with Shopify to bring customer profile and order data into Klaviyo, enable onsite tracking and signup forms, and sync data between Klaviyo and Shopify.
Source: Getting started with Shopify
That data is what helps email become more relevant.
A shopper who viewed a product may need a softer follow-up.
A shopper who added to cart may need a reminder.
A first-time buyer may need post-purchase education.
A repeat buyer may need product recommendations or VIP treatment.
A lapsed customer may need a winback email.
A Klaviyo agency that does not understand Shopify customer behavior may only manage emails.
They may not improve the customer journey.
For the bigger picture, read Klaviyo email marketing for Shopify stores.
What Email Flows Should a Klaviyo Agency Review First?
A strong Klaviyo agency should not start by building random automations.
They should review the flows closest to revenue, retention, and customer experience first.
Flow | What the Agency Should Check |
Welcome flow | Does it guide subscribers toward first purchase? |
Abandoned cart flow | Does it recover high-intent shoppers? |
Browse abandonment flow | Does it follow up without feeling pushy? |
Post-purchase flow | Does it support customers after purchase and encourage repeat buying? |
Winback flow | Does it bring inactive buyers back? |
These flows matter because they match real Shopify customer moments.
Someone joins your list.
Someone views a product.
Someone adds to cart.
Someone buys.
Someone stops coming back.
Klaviyo’s own flow guidance recommends starting with high-impact flows such as welcome, abandoned cart, post-purchase, and winback.

If your core flows are weak, sending more campaigns will not fix the foundation.

How Should a Klaviyo Agency Handle Campaign Strategy?
A good agency should not only ask:
What promo are we sending this week?
That question is too small.
A better agency should ask:
- What are the business goals this month?
- What products matter most?
- Which customer segments should receive this?
- Is this campaign educational, promotional, seasonal, or retention-focused?
- What customer objection are we addressing?
- What did the last campaign tell us?
- What should we test next?
Campaigns should not feel random.
They should connect to a bigger email strategy.
A good campaign calendar may include:
- Product education
- New arrivals
- Bestsellers
- Reviews and social proof
- Promotions
- Seasonal campaigns
- Product launches
- Back-in-stock emails
- Founder or brand story emails
For Philippine Shopify brands, this can also include local ecommerce moments like payday campaigns, double-digit sales, Christmas season, Mother’s Day, Father’s Day, and product restocks.
But the point is the same for any market.
Campaigns should have a reason.
Not just a send date.

Why Segmentation Matters Before Hiring an Agency
A good Klaviyo agency should not send every email to everyone.
That’s one of the biggest hiring signals to watch.
Your email list is not one audience.
It may include:
- Engaged subscribers
- New subscribers
- Non-buyers
- First-time buyers
- Repeat buyers
- VIP customers
- Inactive subscribers
- Cart abandoners
- Product viewers
Klaviyo’s segment conditions allow brands to include or exclude people based on different conditions, including what someone has done or not done, profile properties, location, and list membership.
Source: Segment conditions reference
That means your agency should know how to build campaigns around customer behavior.
Not just send everything to the full list.
If an agency’s only strategy is “send to everyone,” that’s a red flag.

What Reporting Should You Expect From a Klaviyo Agency?
A report should not only show numbers.
It should help you make better decisions.
At minimum, your Klaviyo agency should explain email performance in a way you can understand.
Here are the metrics worth watching:
Metric | Why It Matters |
Open rate | Shows if subject line and sender name are getting attention |
Click rate | Shows if content and CTA drive action |
Placed order rate | Shows if emails help drive purchases |
Revenue per recipient | Shows audience and campaign quality |
Flow revenue | Shows automated email performance |
Campaign revenue | Shows one-time send performance |
AOV | Shows if email helps customers spend more per order |
LTV | Shows if email helps customers buy again over time |
Unsubscribe rate | Shows if emails may feel irrelevant |
Spam complaint rate | Helps monitor trust and deliverability |
AOV means average order value.
It shows how much customers spend per order.
LTV means lifetime value.
It shows how much a customer is worth across their relationship with your brand.
A strong Klaviyo agency should not only report email activity.
They should help you understand how email supports bigger ecommerce goals like higher AOV, stronger repeat purchase behavior, and better customer lifetime value.
Klaviyo’s campaign analytics documentation covers campaign performance reporting, and Klaviyo’s flow analytics documentation explains how to review flow message performance over time.

A useful report should explain:
- What worked
- What did not work
- What to test next
- Which flows need improvement
- Which campaigns drove revenue
- Which segments responded better
- What the next action should be
If the report only shows screenshots and percentages, ask for the story behind the numbers.

How to Think About Klaviyo Agency Pricing
Agency pricing can vary a lot.
So instead of asking only:
How much does it cost?
Ask:
What part of the email system are they responsible for improving?
That question is better.
Because two agencies may charge different rates but include completely different work.
One may only design and send campaigns.
Another may handle strategy, flows, copy, design, segmentation, reporting, testing, and optimization.
Those are not the same service.
Use this table when comparing scope:
Pricing Question | Why It Matters |
Are flows included? | Flows are usually core to Klaviyo performance |
Are campaigns included? | Regular sends require planning and execution |
Is copy included? | Messaging affects clicks and sales |
Is design included? | Layout affects readability and clarity |
Is reporting included? | You need to know what’s working |
Is optimization included? | Email performance should improve over time |
Is Klaviyo setup included? | The foundation affects everything after |
Is strategy included? | Without strategy, email becomes random output |
A cheaper agency may be enough if you only need execution.
But if your Shopify store needs a stronger retention system, you may need a team that can think beyond email production.
Don’t only compare price.
Compare responsibility.
Should You Hire a Klaviyo Agency, Freelancer, or In-House Specialist?
Not every brand needs an agency right away.
Sometimes, a freelancer is enough.
Sometimes, in-house makes more sense.
Sometimes, an agency is the better fit.
Here’s the simple breakdown:
Option | Best For | Watch Out For |
Freelancer | Specific tasks like copy, design, or flow setup | May not cover full strategy or reporting |
Agency | Full strategy, copy, design, build, reporting, and optimization | Costs more, so scope must be clear |
In-house specialist | Brands with enough email volume and budget for ongoing internal ownership | Hiring, training, and management take time |
The right choice depends on how much email support your Shopify store actually needs.
If you only need a few emails designed, a freelancer may work.
If you need full email strategy, campaign planning, flows, reporting, and optimization, an agency may be a better fit.
If email becomes a major revenue channel with constant execution needs, in-house can make sense later.
Questions to Ask Before Hiring a Klaviyo Email Marketing Agency
Before you hire, ask better questions.
Not just:
Can you do Klaviyo?
Ask:
- Do you specialize in ecommerce or Shopify email marketing?
- What Klaviyo flows do you usually audit first?
- How do you plan email campaigns?
- How do you approach segmentation?
- Do you provide copy and design?
- How do you measure performance?
- What does your monthly reporting include?
- How often do you optimize flows?
- What access do you need from us?
- What does your onboarding process look like?
- How do you handle approvals?
- What happens if performance drops?
The answers will tell you a lot.
A weak agency may only talk about deliverables.
A stronger agency will talk about strategy, customer journey, testing, and what they need to learn about your store.
Red Flags to Watch Before Hiring a Klaviyo Agency
Not every agency is the right fit.
Here are red flags to watch for:
- They only talk about email design
- They don’t ask about Shopify data
- They don’t review existing flows
- They send every campaign to everyone
- They promise guaranteed revenue
- They don’t explain reporting
- They don’t ask about product priorities
- They don’t understand customer stages
- They have no clear approval process
- They avoid showing how they think strategically
Guaranteed revenue promises are especially risky.
Email can absolutely support revenue.
But no agency fully controls your product, offer, pricing, traffic quality, stock levels, website conversion rate, customer demand, or market timing.
A serious agency should explain what they can improve and what still depends on the business.
If an agency cannot explain how email supports the customer journey, they may only be managing output.
When Should You Hire a Klaviyo Agency Instead of Doing It Yourself?
You may be ready to hire a Klaviyo agency if:
- You already have traffic and sales
- You have abandoned carts
- Your flows are missing or weak
- You need regular campaigns
- Your team has no time for email
- Your reports are unclear
- You want email to become a stronger revenue channel
- You need strategy, copy, design, setup, and optimization handled consistently
You may not need an agency yet if:
- Your store has almost no traffic
- You only send simple campaigns
- You’re still validating your product
- You’re not ready to invest in email as a channel
This is not about hiring as early as possible.
It’s about hiring when email has enough work to justify the support.

How to Prepare Before Working With a Klaviyo Email Marketing Agency
A good agency should have a clear onboarding process.
But you can make the process smoother by preparing the right assets early.
What to Prepare | Why It Helps |
Shopify access | Lets the agency understand products, orders, and store behavior |
Klaviyo access | Lets them audit flows, lists, segments, campaigns, and reporting |
Brand guidelines | Helps keep email voice and visuals consistent |
Product priorities | Helps campaigns support the right offers |
Bestsellers | Helps with welcome emails, campaigns, and product education |
Promo rules | Prevents incorrect discounting |
Reviews / UGC | Supports trust and social proof |
Product images | Helps with email design |
Past performance data | Shows what has worked or failed |
Approval process | Keeps production smooth |
You do not need to have everything perfect before hiring.
But the clearer your brand assets, priorities, and access are, the faster the agency can work.
For brands that want strategy, copy, design, flow support, campaign planning, segmentation, and reporting handled together, our Klaviyo email marketing services are built around that full email system.
