Flows can stop without anyone touching them.

A new theme, a new pop-up app or a reconnected Shopify integration can stop a flow from firing, and Klaviyo still shows it as Live. A welcome email can slip into Promotions or spam, and your dashboard won't say which tab it landed in.A new theme or pop-up app can stop a flow from firing while Klaviyo still shows it as Live.

What an audit tool reads

  • The flows in your account
  • Your settings
  • Benchmarks for stores like yours

  • Whether your pop-up works on a phone
  • When each email arrives, and in which tab
  • What lands in spam

What the Shopper Test covers, and where it stops

It covers anything a customer can see

  • Your signup forms, on a phone and a desktop
  • Every email that reaches three test inboxes in seven days: when it came, and which tab it landed in
  • Whether your emails pass the sender checks Gmail and Yahoo run (SPF, DKIM, DMARC)
  • Your emails side by side with three competitors: you name them, or I pick

It stops at anything inside your accounts

  • Revenue, list size, segments, and why a flow didn't fire. Those are marked Needs your numbers.
  • Fixing anything. You can, with the report, or we can, on a plan or a project.

Have an agency, a freelancer or an in-house marketer? The test needs no login, so it's a free second opinion and nobody on your side has to do anything.

  1. Abandoned cart

    Klaviyo's advice: a reminder 2–4 hours after the cart, another a day or two later.

    $6.77per recipient

  2. Welcome series

    Often the first flow a store sets up. The question is whether every email in it arrives.

    $5.75per recipient

  3. Browse abandonment

    Catches interest before a cart exists. Often skipped, because it needs the catalog wired up properly.

    $2.08per recipient

  4. Post-purchase

    Upsell, review ask and reorder reminder, aimed at the second order.

    $1.80per recipient

  5. Winback

    For past customers who haven't ordered in a while.

    $0.82per recipient

  6. Back in stock

    The shopper already wants it. This email tells them it's back.

    No Klaviyo figureno Klaviyo figure

Revenue per recipient is what a flow earns per delivered email, from Klaviyo's 2026 Abandoned Cart Benchmark Report (October 2, 2026). It's a per-email benchmark, not total revenue, and not a forecast for your store. Many stores earn below Klaviyo's average.

Why not just use Klaviyo's AI?

Use it where it helps. Klaviyo's Marketing Agent (September 2025) builds campaigns, flows and forms from your URL.1 Flows AI builds a flow's structure from a description.2 Composer, in public beta since June 30, 2026, audits your campaigns, flows and segments, and builds campaigns.3

None of them can be your customer. They work from your account and your website, not the Promotions tab your welcome email lands in, or the "Page not found" behind a signup form. And they don't answer for the result.

My team writes, builds and tests in your account, with a refund if the flows don't pay for themselves in 60 days, counting clicks only, for stores from $30K a month on Core (terms in Chapter 6).

Chapter 4

Work we've done.

Three projects. The first has numbers from the store's own Klaviyo. The other two don't, and I'll say so.

Welcome series · Klaviyo · 2025

Get The Goods

A gifting brand in Whistler, Canada.

What happened: Klaviyo-attributed revenue

CA$6.87K

July 1 to November 1, 2025. 912 delivered recipients, CA$7.53 per recipient. Nearly half of all the email revenue Klaviyo credited to the store in that time came from this one flow.

Klaviyo flow report row: Email Welcome Series with Discount, Live, 922 total recipients at a 98.9% delivery rate, 27 unique added to cart, CA$6.87K conversion value, CA$7.53 per recipient.
Klaviyo's own report, cropped to this flow. Report dated November 1, 2025. Swipe to read the whole row.
The job
A welcome series for new subscribers, with a discount.
What we made
We built the series in their Klaviyo account, and designed and wrote every email in it.

One store's result, not a forecast for yours.

How this is counted

Klaviyo credits an order to an email when the buyer interacted with it within a set window. This figure is that store's own Klaviyo report, with its own attribution settings, which most likely counted opens as well as clicks (Klaviyo's default). My pays-for-itself promise counts clicks only, so it's a stricter count than this one. It's Klaviyo's count, not a Shopify cross-check, and the two often disagree.

Chapter 5

Who does the work.

Why we shop your store instead of asking for your login

Most free audits start by asking for access to your Klaviyo account. I see why: the settings are in there. But your customers never see your settings. They see a pop-up on a phone, a welcome email in the Promotions tab two minutes later, and now and then a "Page not found" where a discount should be. Inside Klaviyo, none of that shows.

So my team and I sign up as your customer and keep notes for a week. What I can prove, I mark Verified. What I can't, I say so, and leave it for your numbers. You shouldn't have to hand over your account to someone before you've seen their work.

If you hire us, my team builds from those notes: a designer, a developer who works in your Klaviyo, and a manager who runs the work with me. I stay your main contact. I've built email since 2018.

Own logins

What it would take.

Klaviyo agencies charge about $1,500 to $3,000 a month for an entry retainer and $2,500 to $10,000 for a full managed program, according to the pricing guide of YOCTO, a Klaviyo agency (September 2026). Copy, design and the build are included in every plan below.

Two promises

Live in 14 days. Three flows are live within 14 days of your start date, or you get your money back. On Core, you pay $400 to start and $400 once they're live: if they're late, you don't pay the second half, and I refund the first. On Growth or Scale, your first month comes back. The clock pauses only while we wait on you, or during a Klaviyo or Shopify outage.

Pays for itself. If the flows we build haven't brought in more Klaviyo-attributed revenue than the fee within 60 days of going live, you get your money back: $800 on Core, or your first month on Growth or Scale. Only clicks count, not opens, though Klaviyo's default counts both. For stores doing $30K or more a month on Core, $50K or more on Growth, or $100K or more on Scale, that keep the flows on as built.

One refund per purchase, paid back the way you paid, within 10 business days of the claim being confirmed. If Core misses the 14 days, you don't have to claim.

Every condition, and how many stores I take

The 14-day promise

What
Three flows are live within 14 days of your start date, or you get your money back: on Core, welcome, abandoned cart and post-purchase; on Growth or Scale, the three highest-earning flows we agree in writing at the start.
Covers
The Core Flows Build, and month one of Growth and Scale.
How Core is paid
$400 with the agreement, before work starts, and $400 when the three flows are live. If they aren't live 30 days after your start date because we're waiting on you, I send the second invoice then.
Your start date
The later of the date we book and the day I have Manager access to your Klaviyo and your brand basics.
The clock
It pauses only while we wait on you (a draft to approve, or a change only you can make in Shopify, your domain or Klaviyo), or during a Klaviyo or Shopify outage.
What comes back
On Core, you don't pay the second $400, and I refund the first within 10 business days of the deadline, without you asking. On Growth or Scale, your first month's fee. Whatever we built stays yours.
Diagnosed first
We shop your store before we build, so the 14 days go on the right flows.

The pays-for-itself promise

What
If the flows we build haven't brought in more Klaviyo-attributed revenue than the fee you'd get back within 60 days of going live, you get your money back. Only clicks count, not opens.
What comes back
$800 on Core, or your first month's fee on Growth or Scale.
Who qualifies
Stores doing $30K+ a month on Core, $50K+ on Growth, or $100K+ on Scale, that keep the flows on as built. Store size is your average monthly sales in Shopify over the three full months before your start date.
How it's measured
The attributed revenue your own Klaviyo flow report shows for the flows we built, over the 60 days from the first one going live, counting clicks only: email and text clicks, with Klaviyo's default 5-day window. Opens don't count, and bot clicks are filtered out. Attributed isn't the same as extra: some of those orders might have come anyway. It's the one count we can both read in your account.
Your account
Clicks only is a setting in your Klaviyo (Settings, then Attribution). It covers your whole account, and Klaviyo recounts past months with it, so your dashboard will show less email revenue. You can preview it with Klaviyo's Compare model button before you hire us, and switch back after we've read the report.
Why the size floor
Below these sizes, the flows may not get enough traffic to pay back in 60 days.
Limits
One claim per store, one refund per purchase. The promises don't stack: on a monthly plan, only the first month's fee comes back.
How refunds are paid
Back to the way you paid, within 10 business days of the claim being confirmed, or of the deadline where I refund without a claim.
  • I take on eight retainer clients at a time, because I stay on every account myself.
  • I start up to two builds a week.
  • I start up to five Shopper Tests a week, in the order they arrive.
  • The free welcome redesign goes to the first four stores each month.

Notes

Questions founders ask first.

Straight answers. Anything else, ask me.

How do I know you're for real?

Check us the way you'd check anyone: a real name (Moin Hossain, also on LinkedIn), a domain email (hello@byteroc.com), prices and promise terms on this page, and a real report page at the top. The test needs no login and no card, so finding out costs you a URL.

Is this just one freelancer? What if you disappear like my last one?

No. There are four of us: me and three salaried team members, each of whom has signed a confidentiality agreement with me. Everything is built inside your Klaviyo from day one, so nothing half-done is stuck with us. Your core flows are live within 14 days of your start date, or you get your money back, on the terms under the plans. And I take eight retainer clients at most, so I stay the contact on every account. If I'm ever out for more than a business day, my manager answers in my place, from the same notes.

Is my customer list safe? What access do you need?

None for the test. To build, you add each of us as a Manager user in your Klaviyo. Manager users can't export your list, and you can remove any of us at any time. If your domain needs SPF, DKIM or DMARC records, I send you the exact records, or work with whoever manages your domain.

Is the Shopper Test a free Klaviyo audit?

Yes, but not the usual kind. Most free audits need access to your Klaviyo account, and read your flows and settings. The Shopper Test needs no login: we sign up as your customer and record what actually arrives, when, and in which tab. So it can't see your revenue, list size, segments, or why a flow didn't fire. The report marks those Needs your numbers. It's free for Shopify stores, one test per store every six months, and it still works if you're not on Klaviyo.

Is the free test a sales pitch?

Partly, and I'll say so: I hope you'll hire us afterwards. The report is yours either way. We sign up with our own addresses, leave a test cart, and unsubscribe after day 7. One free test per store every six months.

Won't the time difference slow things down?

Message me by 5 p.m. Eastern and you'll have my reply by 9 a.m. Eastern the next business day: my working day is your night. The test runs on fixed clocks: first findings in 48 hours, the report on day 7. On Growth and Scale there is a weekly check-in.

How do refunds work?

On the terms in the box under the plans. On the Core Flows Build, you pay $400 to start and $400 once your flows are live. If they miss the 14 days, you don't pay the second half, and I refund the first without you having to ask. Any other refund goes back to the way you paid, within 10 business days of the claim being confirmed. One refund per purchase, and on a monthly plan only the first month's fee.

Klaviyo and Shopify show different email revenue. Which do you count?

Klaviyo's, counted on clicks only. For the pays-for-itself check, I read your own Klaviyo flow report for the flows we built, with your attribution set to count email and text clicks, no opens, and bot clicks filtered out. Klaviyo's default also credits orders to emails that were only opened, and Apple Mail can record an open on its own, which is why the default reads high. Shopify counts its own way, so the two will still disagree. That's why the counting rule is written into the terms before you start.

I already have flows, or someone running them. Is this still worth it?

Probably. The test sees what a shopper sees: your pop-up on a phone, and where each email lands. It needs no login, so it's a free second opinion on whoever runs your Klaviyo, and nobody on your side has to do anything. If your flows are strong, the report says so, and it costs you nothing.

Is there a contract? What do I keep if I stop?

A one-page agreement: month to month, 30 days' notice, no exit fee. Every flow, template and email is assigned to you in writing, and stays in your account, with your list, if you stop.

How fast will I see a return?

Flows are due live within 14 days of your start date, and they only catch shoppers who arrive after that. Abandoned cart usually moves first. I don't publish an average return: one store's result isn't a forecast for yours.

Still deciding?
