Klaviyo Agency vs Freelancer vs DIY: How to Choose Without Wasting Money

Agency vs Freelancer vs DIY — how to choose your Klaviyo partner without wasting money

Somebody told you to “get your Klaviyo sorted.” Maybe it was a friend with a Shopify store. Maybe you looked at your own numbers and realised email is barely pulling its weight. Either way, you’ve arrived at the question every founder eventually hits: who actually builds this thing?

There are three answers. Hire an agency. Hire a specialist or freelancer. Or do it in-house. And almost every article comparing these options was written by an agency — which is why they all somehow conclude that you should hire an agency, preferably that one.

I’ll try to be more useful than that.

I run a small Klaviyo practice, so I have a horse in this race. I’ll tell you exactly where my bias sits, and I’ll also tell you when you genuinely shouldn’t hire someone like me. By the end, you should know which of the three paths fits your business right now — not in some ideal world, but at the stage and budget you’re actually working with.

The three paths, quickly

An agency is a team. You get strategists, designers, copywriters, and an account manager, usually working on a monthly retainer. Breadth is the selling point.

A freelancer or specialist is one experienced person (sometimes a tiny team) doing the work directly. Depth and direct access are the selling points. This is the lane I work in, so read my take on it with that in mind.

DIY or in-house means you, or someone on your team, learns Klaviyo and runs it yourselves. The software does a lot of the heavy lifting; the question is whether you have the time and the stomach for the learning curve.

None of these is “best.” They’re tools for different situations. Let’s go through when each one is actually the right call.

When an agency is the right move

I’m going to argue for agencies for a second, because sometimes they’re genuinely the answer.

If you’re a larger brand running email, SMS, push, paid social, and direct mail all at once — and you need all of it managed every week, forever — an agency is built for that. One person can’t sustainably run six channels at a high volume. A team can. You’re paying for capacity and coverage, and at a certain size that’s worth every cent.

Agencies also make sense when you need redundancy. If the one person who knows your account gets sick, a team keeps moving. A solo specialist can’t offer that, and pretending otherwise would be dishonest.

The tradeoffs are real, though, and worth saying out loud:

When a specialist or freelancer is the right move

Here’s where most growing Shopify and DTC brands actually land — and where my bias is, so weigh it accordingly.

If your main need is to get your Klaviyo built properly — flows, segments, deliverability, the integration with your store wired up correctly — a specialist gets you the senior person’s hands directly on the work. No account-manager layer. No “let me check with the team.” You talk to the person who’s actually building it.

It’s usually faster, because you’re not entering a large agency’s production pipeline. It usually costs less, because you’re not paying for an office, a sales team, and ten other salaries. And the work is often more careful, not less, because the person’s name is attached to it and their reputation lives or dies on the result.

The honest tradeoffs: a specialist has limited capacity. There’s no big team to absorb a sudden tripling of your workload. If you need five channels managed daily and forever, one person isn’t the right structure — that’s the agency’s job. And you have to actually vet the person, because “freelancer” covers everyone from world-class operators to someone who watched a few tutorials last month. Credentials, verifiable reviews, and real dashboard screenshots matter here.

When doing it yourself makes sense

Plenty of people skip this option because an article like this is “supposed” to talk you into hiring someone. But DIY is the right answer more often than the industry admits.

If you’re early — say, still finding product-market fit, or your store is doing modest volume — your money is better spent on getting customers than on a polished retention program you don’t have the traffic to feed yet. Klaviyo’s free tier and built-in templates will carry you further than you’d think at that stage.

DIY also works if you’ve got someone in-house with time and curiosity. Klaviyo isn’t impossible to learn. The flows that drive most of the value aren’t exotic. If you or a team member can commit real hours to it, you can build a respectable program yourself.

The catch is the stuff you don’t know you don’t know. The most common DIY failure isn’t bad copy — it’s quietly broken deliverability, or flows with the wrong filters firing to the wrong people, or an integration that silently stopped syncing months ago. Those mistakes cost real money, and they’re invisible until someone who’s seen them before points them out.

The questions that actually matter when you’re choosing

Forget the marketing for a minute. Whether you’re talking to an agency, a freelancer, or weighing DIY, these are the questions that separate a good decision from an expensive one:

Let’s talk about cost honestly

I’m not going to throw fake numbers at you, because pricing in this space varies enormously and anyone quoting you a single figure is guessing. But the models are worth understanding, because they’re structurally different.

Agencies generally charge a recurring monthly retainer, often with a minimum term. You’re buying ongoing capacity, so you pay on an ongoing basis — whether or not there’s a big project that month.

Specialists and freelancers more often charge per project or at lower recurring rates. You pay for a defined outcome — “build my flows,” “fix my deliverability,” “set up my loyalty integration” — rather than renting a team indefinitely. Rates range wildly based on the person’s experience, so the number matters less than what you’re actually getting for it.

DIY costs you the software subscription plus your time. The subscription is the small part. Your time is the real cost, and whether that trade is worth it depends entirely on what your hours are worth elsewhere in the business.

The mistake I see most often isn’t overspending or underspending. It’s paying for the wrong model — a small brand locked into a retainer it doesn’t need yet, or a large brand trying to run everything through one overloaded freelancer. Match the model to your stage, and the price tends to sort itself out.

So which one should you pick?

Here’s the short version, with no hedging:

The worst outcome isn’t picking “wrong.” It’s picking based on who marketed at you hardest. Pick based on your stage, your budget, and honest answers to the questions above.

And if you’re in that middle group — a growing Shopify or DTC brand that wants the work done properly without an open-ended contract — that’s exactly what Aurora is built for. See what’s in the shop →

Frequently Asked Questions

Is a freelancer riskier than an agency?

It can be, if you don’t vet them. A team gives you redundancy a solo person can’t. But a strong specialist often does more careful work than a junior account manager at a large agency, because their name is on the result. Reduce the risk by checking verifiable reviews, real credentials, and actual dashboard screenshots before you commit.

How much does a Klaviyo setup cost?

It depends heavily on scope and who’s doing it. Agencies typically work on recurring retainers; specialists more often price per project; DIY costs you the subscription plus your time. Rather than chasing a single number, get clear on exactly what’s included — flows, segments, deliverability, integration, post-launch support — and compare like for like.

Can one person really replace a whole agency?

For building and optimising a Klaviyo program, often yes. For running five channels at high volume every single day, no — that’s genuinely a team’s job. Match the structure to how much ongoing work you actually have.

I’m a small store. Should I even hire anyone yet?

Maybe not. If you’re early, spend on acquisition first and run a basic program yourself using free guides. Bring in help once you have enough traffic and revenue for a retention program to pay back. Loyalty and lifecycle compound with customer volume — you need the customers first.

What’s the single biggest thing to check before hiring?

Deliverability competence and who does the actual work. A provider who can’t speak fluently about inbox placement, or who can’t tell you who’ll be in your account day to day, is a provider to be cautious about — regardless of whether they call themselves an agency or a freelancer.
