Klaviyo email marketing

We build and run the Klaviyo flows most stores never set up

Sidekicks is a Klaviyo email marketing agency working with Shopify brands doing $1M to $5M. Most of the accounts we open have two flows running and eight that were never built, and that gap is usually the whole difference between email as a small channel and email as a real one. Nobody builds ten flows at launch. They get added when there is time, and there is never time.

Email is the one channel you already own. The list is yours, the sends cost close to nothing, and nobody can raise the price on you mid-quarter.

Flows running 2 / 8

The typical account we open. A welcome sequence, an abandoned cart, and six sequences that were never built.

The shape of it

Where email revenue actually comes from

Most brands treat email as a campaign channel. Send a newsletter, send a promotion, send something for the holiday. That work is visible, it takes time every week, and it is the smaller half of the revenue.

The larger half runs on flows, meaning the automated sequences that fire when someone does something. Those send whether or not anyone touched Klaviyo that week, they reach people at the moment they were already interested, and once built they keep working.

The gap

The flows that are usually missing

Almost every account has a welcome sequence and an abandoned cart. Usually the welcome is three emails and the cart is one. Here is what is usually absent.

01Browse abandonmentFor people who looked at a product and never added it.
02Post-purchaseWhere the second order comes from and where reviews get requested.
03WinbackFor customers who bought once and went quiet.
04ReplenishmentIf anything you sell runs out on a predictable schedule.
05Back in stockThe highest-intent email you will ever send.
06Review requestTimed to when the product has actually been used.

None of those are complicated. They are missing because building them is a week of work nobody has had, and because Klaviyo ships with two templates and no opinion about the rest.

The other half

Campaigns, on a calendar

Flows do the compounding. Campaigns do the rest, and they work better when they stop being decided on the day they send.

We run a calendar built against your product cycle, your inventory, and whatever is seasonal in your category. Segmentation comes from behaviour rather than from a single list, so a customer who bought last week and a subscriber who has never bought get different sends.

The quiet one

Deliverability and list health

The part nobody notices until it breaks. If a meaningful share of your list stopped opening a year ago and still receives every send, inbox providers read that as a signal and your reach quietly falls. The revenue drop shows up months before the cause does.

Clean the list

Suppression that runs on its own rather than as an annual chore.

Authenticate the domain

Set up properly rather than left on the platform default.

Watch placement

Rather than assuming a send that reported as delivered actually arrived.

List health, meaning the share of your list that is genuinely engaged, matters more to your reach than the size of the list does. It is the part Klaviyo experts spend most of their time on and the part nobody asks about.

Alongside

SMS

SMS runs out of the same account and it works on different rules. Shorter list, higher cost per send, much higher tolerance for being ignored if you get the frequency wrong.

We use it for the moments where speed is the point. Back in stock, order updates, and a narrow set of promotions. It sits alongside email rather than duplicating it.

Ownership

What you keep

The list, the flows, the templates, and the segments. Everything is built inside your Klaviyo account rather than ours.

This matters more on email than on any other channel, because the list is an asset you own outright and the flows keep sending after we stop working together. A paid account stops the day the budget does. A welcome flow does not.

What does a Klaviyo email marketing agency cost?

It starts at $1,800 a month after a $2,995 setup. The setup is where the flow build happens, so it is heavier than the monthly and it happens once.

How much revenue should email be?

For a Shopify brand doing $1M to $5M with a normal repeat purchase rate, email usually lands between 28 and 32 percent of total revenue when the flows are built. Accounts running only a welcome and a cart tend to sit around 15. Your own number depends on your category and how often people reorder.

How long before the flows produce anything?

Flows start sending the day they go live, so revenue moves faster here than on any other channel we run. Most accounts see flow revenue change inside 30 to 45 days. The compounding part, meaning list growth and segmentation getting sharper, takes longer.

Do we need to send more campaigns?

Usually not. Most accounts we open are already sending enough and are missing the automated sequences underneath. Adding campaign volume to a thin flow setup increases the work without changing much, and it raises unsubscribes.

Do you write the emails or do we?

We write and design them. Copy, layout, and the segmentation logic all come from us, built against your brand rather than from a Klaviyo template.

What if our list is old and unengaged?

That is common and it is fixable. A list that has not been cleaned in two years is suppressing your own reach, and the first month usually involves sending to fewer people rather than more. Revenue tends to rise anyway, because the sends that go out actually arrive.

Do you work in Klaviyo only?

Klaviyo is where most Shopify brands at this size are and it is where we work fastest. If you are on something else we will look at whether moving is worth it rather than assume it is, since a migration costs time that could have gone into flows.

Do you do SMS as well?

Yes, out of the same account. It works on different rules than email and we use it where speed matters, like back in stock and order updates, rather than as a second promotional channel.

Two business days

Start with the audit

Part of the free audit is Jimmy signing up to your list and abandoning a cart, so we see exactly what a real subscriber gets in the first forty-eight hours and what never arrives. Two business days later you have the findings, and they are yours to run with.
