Strategy, flows, campaigns, design and reporting, run by a certified team.
Most brands we speak to already have Klaviyo. What they do not have is the flows, the segments or the time to use it properly, so email ends up contributing a fraction of what it should. The industry benchmark is roughly a quarter of ecommerce revenue.
Our Klaviyo work is led by Victoria ap Gwynedd, a Klaviyo Champion and one of the platform's chosen ambassadors. She sits alongside our developers, designers, CRO specialists and analysts, which matters more than it sounds: when a flow needs a change on the website to work properly, that change gets made rather than added to somebody else's backlog.

Full-service ecommerce agency
Development, CRO, analytics and acquisition alongside retention.
Six things brands come to us for.
Klaviyo implementation
Moving to Klaviyo or setting up a new account. We manage account configuration, customer data, integrations, lists, core flows and templates to give your team the right foundations from day one.
Email marketing campaigns
Strategy, planning, creative and campaign delivery built around your commercial calendar. We use customer data and performance insights to create email campaigns designed to engage customers and generate measurable revenue.
Automation and flow creation
Automated journeys that communicate with customers at the moments that matter. From welcome and abandoned cart flows to post-purchase, win-back and bespoke lifecycle journeys, we build automation around the way your customers behave.
Segmentation and personalisation
Using Klaviyo's customer data to move beyond one-size-fits-all messaging. We build meaningful audience segments based on behaviour, engagement and purchase history, allowing campaigns and flows to become more relevant as your data grows.
Email and SMS design
Our in-house creative team designs responsive email and SMS experiences that feel consistent with your wider brand. Templates are built to be engaging, easy to manage and designed around the requirements of ecommerce marketing.
Deliverability and optimisation
Already using Klaviyo? We audit the account, campaigns, flows, segmentation and performance to find what can be improved. That includes the technical work most retention agencies skim over: SPF, DKIM, DMARC and BIMI records, sending domain setup, sender reputation, list hygiene and engagement-based suppression. If your emails are landing in the promotions tab, the fix is usually in DNS rather than in the subject line.
01
Gold Master is Klaviyo's designation for agencies that manage client accounts directly, and it is earned on delivered results and team-wide certifications. We keep the number of Klaviyo accounts we run deliberately small, so each one gets senior attention from people who know the platform properly.
02
Victoria ap Gwynedd is a Klaviyo Champion and one of the platform's chosen ambassadors, with particular experience of the luxury and considered-purchase journey. Very few UK agencies have that depth of platform knowledge sitting in-house rather than contracted in.
03
Boodles grew open rates 80% on engagement ring campaigns after we rebuilt their flows. Ehrman Tapestry grew email revenue 21% and click-through 114% through segmentation. The Conran Shop grew email revenue 23% after we moved them onto Klaviyo during their replatform.
04
Retention rarely fails for email reasons alone. A wish list flow needs the wish list to work. A browse abandonment flow needs the tracking to fire. Because our developers, CRO specialists and analysts sit alongside the Klaviyo team, those things get fixed instead of blocking the work.
05
Klaviyo stopped being an email tool in 2025. It is now a B2C CRM, with marketing, analytics and service sitting on one data platform, and Customer Hub turning order tracking, returns and support into a signed-in experience that also sells. We have implemented Customer Hub for clients, which needs storefront development as well as configuration inside Klaviyo. Most agencies still treat the platform as a flow builder, so nobody tells you which parts you are already paying for and not using.
06
Everything we build sits in your Klaviyo account, under your login, including your sending domains and deliverability history. If you ever move on, you keep the flows, the segments and the sender reputation you have built, and we document the handover. Worth asking any agency before you sign, because not all of them work this way.

Boodles had Klaviyo but were missing the flows that matter for a considered purchase, and email was well below benchmark as a share of revenue. We audited the account, then built the journeys the jewellery buying process actually needs: a Drop a Hint flow, wish list reminders, browse abandonment and post-purchase cross-sell. Webhooks now alert the sales team when a customer does something worth a personal follow-up, so online behaviour reaches the people in the showrooms.
Increase in open rates
+80%

Ehrman depend on repeat orders from a loyal customer base, but every customer was receiving the same standard email and the team had almost no reporting to work from. We audited the database, segmented it by purchase behaviour, moved them onto Klaviyo, built the flows, templates and campaign plan around it, and trained their team to run it.
Email marketing revenue
+21%
Email click-through rate
+114%

We introduced Klaviyo as part of The Conran Shop's move from Magento to Shopify Plus, which is the useful thing about having both teams in one building: the retention platform was set up around the new data model rather than bolted on afterwards. More personalised campaigns followed.

A Klaviyo agency helps businesses implement, manage and optimise the Klaviyo platform. Depending on your requirements, this can include account setup, platform migration, integrations, email and SMS campaign management, automated flow creation, segmentation, template design and ongoing performance optimisation.
It depends on how much of the work you want us to take on. Some clients use us for a few hours a month to review performance, keep flows healthy and sense-check the campaign plan. Others have us running the whole retention programme every week, covering strategy, campaigns, flows, design and reporting. A one-off implementation or account rebuild is scoped as a project with a fixed figure. Either way you get a monthly number before anything starts.
Our Klaviyo work is led by Victoria ap Gwynedd, a Klaviyo Champion and one of the platform's chosen ambassadors, supported by our in-house designers for templates and analysts for reporting. You get a named contact who knows your account and your customers rather than a rotating queue.
Yes, and we have done for clients. Customer Hub is Klaviyo's signed-in shopper experience, bringing order tracking, returns, subscriptions, product recommendations and support together in one place. It needs development work on the storefront as well as configuration inside Klaviyo, which is where being both a Klaviyo partner and a Shopify Premier partner matters. Our developers build the storefront side while the Klaviyo team sets up the data and service logic.
You do. Everything we build sits in your Klaviyo account under your login, including your sending domains and deliverability history. If you ever move on, you keep the flows, the segments and the sender reputation you have built, and we document the handover. It is worth asking any agency this before you sign, because not all of them work that way.
Regularly. Most brands we speak to already have Klaviyo but are not getting much from it. We normally begin with an account audit covering campaigns, flows, segmentation, customer data, deliverability and integrations, then prioritise the opportunities likely to have the greatest impact.
Yes. Deliverability is a technical problem before it is a creative one. We check SPF, DKIM, DMARC and BIMI records, sending domain configuration, sender reputation, list hygiene and engagement-based segmentation, then fix the causes rather than rewriting subject lines and hoping. Because we also build ecommerce platforms, we can change DNS and on-site capture as part of the same piece of work.
Yes. We manage migrations to Klaviyo from other email and retention platforms. This can include transferring customer data and lists, setting up integrations, recreating or improving existing automations and building the templates and account structures needed before launch.
We report on attributed revenue and repeat purchase rather than open rates alone, so it becomes visible early if something is not working. If a flow or a campaign approach is not performing we rebuild it rather than defend it. Ongoing retainers carry a three month notice period.
The right flows depend on your customers and business model, but common ecommerce automations include welcome, abandoned browse, abandoned cart, post-purchase and win-back journeys. We review customer behaviour and your wider retention strategy before deciding which flows to prioritise rather than implementing the same structure for every brand.
Yes. We can plan and manage email and SMS activity together, creating coordinated customer journeys instead of treating each channel separately. This allows messaging to be planned around the wider customer lifecycle and helps avoid unnecessary overlap between channels.
Yes. We work across major ecommerce platforms including Shopify, Shopify Plus and Adobe Commerce, and can connect Klaviyo with the wider systems that influence your customer data. As a Shopify Premier partner we also build the on-site changes a flow sometimes depends on, rather than handing you a specification for someone else to implement.
Klaviyo distinguishes between partners who refer clients and partners who manage accounts directly. Master applies to the second group, which is what we do. Tiers within that are earned on delivered results and team-wide certifications rather than bought, and ours is Gold Master. The part worth more than the tier is having a Klaviyo Champion on staff, which is a personal certification rather than an agency one.
Yes. We provide ongoing Klaviyo support covering campaigns, automated flows, segmentation, testing, reporting and optimisation. We can act as an extension of your internal team or manage your retention marketing activity on an ongoing basis.
We look beyond individual campaign open and click rates to understand the commercial impact of retention activity. Depending on your objectives this can include attributed revenue, conversion, flow performance, repeat purchasing, customer engagement and the contribution of email and SMS to wider ecommerce growth.
