Expanding your tech stack for retention & engagement
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 programs 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 D2C 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.
