We help you bridge gaps in your retention strategy and introduce you to the right partners, integrating loyalty, referral, and engagement solutions with data-driven personalisation.
-
We help you design and implement loyalty programmes that integrate directly with Klaviyo, so every reward, tier update and redemption feeds back into your lifecycle. Paired with referral marketing, it becomes a full retention and acquisition loop, where your best customers feel recognised and keep coming back because of it.

Your existing customers are often your best acquisition channel. We build referral marketing programmes for DTC brands that connect seamlessly with your email and SMS strategy, turning satisfied buyers into a consistent source of new, high-quality customers.

We layer customer personalisation across your ecommerce experience, from dynamic email content to on-site recommendations, so every touchpoint feels relevant. The more your communications reflect individual behaviour, the stronger the relationship you build over time.
-
We help you collect, manage and activate reviews and UGC across your lifecycle within email campaigns, flows and SMS, making use of a versatile retention marketing tech stack. Social proof at the right moment reduces hesitation and builds the kind of trust that turns first-time buyers into repeat customers.

Frequently Asked Questions
-
Our retention marketing retainer covers end-to-end Klaviyo account management from strategy, segmentation, campaign creation and flow builds to reporting, optimisation and ongoing testing. The exact scope is tailored to your brand, but the goal is always the same: a fully managed email and SMS programme that grows with your DTC brand.
-
Our CRM audit is a standalone, deep diagnostic of your existing Klaviyo setup that identifies gaps, quick wins and longer-term opportunities within your retention strategy. The retention marketing retainer is an ongoing partnership where we manage and optimise your programme month to month. Some brands start with an audit before moving into a retainer. Others come straight to us ready to hand over.
-
We work best with premium DTC and ecommerce brands in fashion, beauty, wellness, and food and beverage that are established, growing steadily, seeing consistent traffic, and ready to scale their customer retention through email and SMS marketing. As a boutique Klaviyo agency, we only take on a select number of clients at a time, so fit matters as much to us as it does to you.
-
Yes, and most of our clients are. We have deep expertise in Klaviyo, including auditing existing accounts, improving underperforming setups, and rebuilding flows and campaigns where needed. As a Klaviyo Platinum Master Partner, we consider it a core part of our work. That said, we keep our approach flexible and can also support brands using other platforms, as well as broader retention systems such as Manychat automations and related social channels.
We also support Klaviyo migrations for brands moving from other CRM platforms, handling everything from data and flows to ensure a smooth transition without disrupting your existing performance.
-
Email marketing agency onboarding typically takes one week and covers strategy alignment, account access, and any foundational work required before we go live. This does not include our in-depth audits, which take around three weeks. Flows typically go live within four to five weeks, and early results and small wins often show up within the first month. Compounding results, the kind that come from a fully optimised lifecycle, build over the first 90 days and beyond.
-
Yes. We’re a UK-based Klaviyo agency and retention marketing agency, but we work with eCommerce and DTC brands internationally. Our clients are based across Europe, the Middle East, Asia, North America and Australia. Klaviyo is a global platform, and we regularly support brands in different markets, time zones and growth stages. If the brand is the right fit, location is not a barrier.
-
We're a boutique Klaviyo agency and Klaviyo Platinum Partner, which means we have a deliberately small, senior team. Every client works directly with experienced Klaviyo strategists specialising in retention for premium DTC brands, which means the work is focused, the relationships are close, and we have a proven track record for results.
