Klaviyo flows for founder-led Shopify brands
Klaviyo flows, built by the person who audits them.
I shop your store like a real customer for 7 days, then show you every email you sent, when it arrived, where it landed and what's missing. First findings in 48 hours.

You're not missing email. You're missing about six flows.
The usual picture: the platform's default emails and a newsletter. The revenue is in the sequences nobody built.
What's probably running
- Klaviyo's default abandoned-cart email, untouchedThe default abandoned-cart email, untouched
- One welcome email
- Nothing after the order confirmation
- Campaigns to the whole list
- No winback, no browse abandonment, no VIP tier
What a complete program runs
- A three-email cart sequence with real timing
- A four- to five-email welcome series
- Post-purchase upsell, review ask and reorder
- Segmented sends instead of one list
- Winback, browse abandonment and VIP running on their ownWinback, browse abandonment and VIP
In the best-run DTC programs, email and SMS drive 30 to 40% of revenue.1

The flows that make the money.
Six sequences, ranked by what each one returns per recipient on Klaviyo's 2026 data. Your Shopper Test shows which of these reached my test inboxes that week, and ranks the gaps it can see using the same figures.
-
Abandoned cart
Three emails with real timing and real copy, not the one default message your platform shipped with.
$6.77per recipient -
Welcome series
The one flow most stores already have, running at a single email. Four or five is where it earns.
$5.75per recipient -
Browse abandonment
Catches intent before a cart exists. Often skipped, because it needs the catalog wired up properly.
$2.08per recipient -
Post-purchase
Upsell, review ask and reorder reminder: the part of the program that compounds.
$1.80per recipient -
Winback
The cheapest revenue in the account: people who bought from you once and stopped hearing from you.
$0.82per recipient -
Back in stock
Often missing. The shopper already wants it. This email tells them it's back.

The Shopper Test: I become your customer for a week.
No login and no call. I sign up with Gmail, Outlook and Yahoo addresses, browse and leave a cart, then show you every email you sent, when it arrived and where it landed. An audit tool reads your settings. Only a shopper sees what actually arrives.

First findings
- Does your signup form work on mobile and desktop?
- Your first welcome email, and your cart email if it has fired, with timings
- Inbox, Promotions or spam, as my test inboxes on Gmail, Outlook and Yahoo saw it
- SPF, DKIM and DMARC, checked
The full route
- Every email you sent all week, on one timeline
- Side by side with three competitors you name
- The 14-point check, every gap ranked by what that flow typically earns on Klaviyo's 2026 benchmarks
- What to fix first, and what it would take
The first four stores each month also get their welcome email redesigned by me, in their brand: a finished phone and desktop design with the copy, yours to use. Hire me and I build it into your Klaviyo in week one. No case study required. I design them myself, which is why there are only four.
And the written part looks like this.
Your only email capture form redirects new subscribers to a 404.
The footer form offers "$10 off instantly". The page it sends people to returns HTTP 404, "Page not found". We fetched it live to confirm the status code, not just the rendering.
Finding 1 from a real report, shortened.A real report. I can't disclose the store, so its name is blacked out.
Every finding is marked one of two ways.
- Verified
- Seen on your live store, and you can reproduce it yourself in about a minute.
- Needs your numbers
- A model, not a claim, until a figure from inside your Shopify or Klaviyo account settles it.
And one section is titled "What we could not see, and did not guess."

From one welcome series, for a Canadian ecommerce brand.
As Klaviyo reports it: attributed revenue across 912 delivered recipients, July 1 to November 1, 2025. One store's result, not a forecast for yours.
"He understood exactly what we needed and delivered clean, professional, and responsive designs. Every email… looked great and matched our brand perfectly."
"[He] proposed a staged solution and executed it phase by phase. He has high standards and worked hard to meet our goals."

The pays-for-itself promise. If the flows I 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: the $800 on a Core Flows Build, or your first month on Growth or Scale. For stores doing $30K+ a month (Core), $50K+ (Growth) or $100K+ (Scale) that keep the flows on as built. Promise terms
The 14-day promise. Your three core flows are live within 14 days of your start date, or you get your money back. The clock pauses only while I'm waiting 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. Applies to the Core Flows Build and to month one of Growth and Scale. Promise terms
The promises don't stack. One refund per purchase; on a monthly plan, only the first month's fee.

You work with me, not an account manager. I test your store, write your report and build your flows myself. I'm based in Dhaka, ten hours ahead of New York (eleven in winter), so the work is done before your morning starts. Building email since 2018.

Is the Shopper Test really free?
Yes, for Shopify stores, one test per store every six months. No card, no login and no call. You see the quality of the thinking before you spend a dollar. Your store will show test sign-ups from my Gmail, Outlook and Yahoo addresses, and one abandoned checkout from me. When the week is over I unsubscribe from your list, and the report is yours to keep whether you hire me or not.
Do I have to get on a call?
No. The report arrives written. If you want to talk it through afterwards, that's your choice, not a condition of getting it.
I already have flows running. Is this still worth it?
Probably. Some of what matters can only be seen from the shopper's side: whether your pop-up works on a phone, how fast the first email arrives, and whether it lands in the inbox or Promotions. If your flows are strong, the report says so, and it costs you nothing.
Why not Klaviyo's own AI or templates?
Use them for a start. A template gives you the trigger and a placeholder email, and Klaviyo's Composer can draft a flow from a prompt. Neither knows your products, your voice, who to leave out, or when the second and third emails should go. Neither can sign up on your phone and find your pop-up sends people to a 404, see your welcome email land in Promotions, or put your inbox next to three competitors'. That's the work, and it's why every plan includes the copy and design.
You're one person. What if you disappear like my last freelancer?
Fair question. Three things are different. Everything is built inside your Klaviyo account from day one, so nothing half-done is stuck with me. Your core flows are live within 14 days of your start date, or you get your money back (terms). And I take on three retainer clients at a time, so yours always has my attention.
What access do you need to build?
None for the Shopper Test. To build, you add me as a Manager user in your Klaviyo account. Managers can build flows and campaigns but can't export your customer list, and you can remove me whenever you like. If your domain needs SPF, DKIM or DMARC records, I send you the exact records, or work with whoever manages your domain.
How much of my time does this take?
None for the test after you send the form. For a build: a short brief at the start, then you approve the emails in batches before anything goes live.
What happens after the report?
You decide. Fix it yourself with the report, hire me for one project, or pick a plan. I follow up once, a few days after the report. If you don't reply, that's the end of it.
Is there a contract?
A one-page agreement, not a long-term contract. Month to month, 30 days' notice, no exit fee, and it assigns every flow, template and email to you in writing.
Who owns the work?
You do, permanently. Every flow, template and campaign is built inside your own Klaviyo account. There's nothing to hand back.
We're not on Klaviyo. Can you still help?
Klaviyo is my specialty. If you're on Shopify Email, Omnisend or Mailchimp, the Shopper Test still works, and it will tell you honestly whether moving is worth it. If it is, Move to Klaviyo is $1,200 fixed, up to 25,000 profiles.
