KLAVIYO AGENCY — UK
A Klaviyo agency that
runs its own stores.
Most Klaviyo agencies have never had to live with the consequences of a bad send. We have. We run our own Shopify brands, and every email we build comes out of our own margin first. Flow architecture, segmentation, SMS, migration and revenue attribution for UK ecommerce businesses.
Email that works
because we've tested it.
Most email marketing is noise. Batch-and-blast campaigns with generic discounts that train your customers to wait for a sale. We take a different approach because we've had to — we run our own stores and every email we send comes out of our own margin.
We build Klaviyo flows that are triggered by real customer behaviour: what they bought, what they browsed, when they last engaged. Proper segmentation means higher open rates, better deliverability, and more revenue per recipient.
From welcome sequences that set the tone to win-back flows that re-engage lapsed customers, every automation is built with one goal: revenue that doesn't require you to hit send.
HOW WE WORK
A clear process for
measurable results.
Review email performance, fix tracking, build proper segmentation. We audit what you have, identify gaps, and configure Klaviyo for accurate attribution.
Design and build core automated flows — welcome, cart abandonment, post-purchase, browse abandonment, and win-back. Every flow earns revenue while you sleep.
Monthly campaign calendar aligned with your promotions, product launches, and seasonal peaks. Segmented sends, not spray-and-pray blasts.
Ongoing A/B testing on subject lines, send times, and content. Segment refinement based on engagement data. Revenue attribution so you know exactly what's working.
WHAT TO EXPECT
Numbers that matter.
Across the Shopify stores we own and operate, email and SMS account for over 30% of total revenue. That is our own trading experience, not a projection for your store — your baseline, catalogue and list size will differ.
Cart abandonment, browse abandonment and checkout recovery sequences run on our own stores before we recommend them to anyone else.
Right message, right person, right time. Proper segmentation protects deliverability and drives higher revenue per recipient.
BEFORE YOU HIRE ANYONE
How to choose a Klaviyo agency.
Klaviyo is easy to buy and hard to run well. If you are comparing agencies, these are the questions that separate the ones who will move revenue from the ones who will send you a campaign calendar and an invoice.
1. Who actually builds the flows?
Ask whether the person in the pitch is the person in your account. Flow architecture is a technical job — conditional splits, profile properties, suppression logic. It is not a copywriting task with a send button.
2. How do they handle deliverability?
If an agency cannot explain domain authentication, sending reputation, engagement-based suppression and a sunset policy, they will grow your list and quietly shrink your inbox placement.
3. How is revenue attributed?
Klaviyo's default attribution window is generous. Ask how they separate email-driven revenue from revenue that would have happened anyway, and whether they will report against your Shopify numbers rather than only Klaviyo's dashboard.
4. Do they run stores themselves?
An agency that has never absorbed the cost of a bad send optimises for activity. An operator optimises for margin. Ask what they sell, where, and what their own email programme looks like.
5. What happens to your account if you leave?
Your Klaviyo account, flows, segments and data should be yours. Check that nothing is built inside an agency-owned account and that documentation comes with you.
6. Is the scope flows, campaigns, or both?
Flows earn while you sleep; campaigns earn when you send. Most underperforming programmes are campaign-heavy and flow-light. Be clear which you are paying for.
WORKING TOGETHER
Common questions.
Do you work with brands not on Shopify?
Klaviyo integrates with several platforms, but our operating experience is Shopify. If you are on something else, say so early and we will tell you honestly whether we are the right fit.
Can you migrate us from Mailchimp or another platform?
Yes. Migration covers list hygiene, profile properties, consent status, flow rebuild and a deliverability warm-up plan — not a raw contact dump.
What does a Klaviyo engagement cost?
It depends on whether you need a one-off flow build or ongoing flow and campaign management, and on list size. We will give you a scope and a fixed monthly figure before you commit. If email is not currently the right investment for your stage, we will say so.
How long before we see anything?
Core flows can be live within weeks. Meaningful evidence takes a full purchase cycle, because your repeat-purchase interval — not our schedule — decides how quickly post-purchase and win-back flows can prove themselves.
Do you do SMS as well as email?
Yes, where it earns its place. SMS is expensive per send and unforgiving of poor targeting, so we use it for time-sensitive and high-intent moments rather than as a second broadcast channel.
Who will we deal with?
You will work directly with the people building the account. We deliberately work with a small number of clients at a time.
