We build Shopify Plus stores and run Klaviyo on top of them, so your retention is wired into the store, not bolted beside it. Design-led, AI-enabled, built for APAC. Doing both is where the advantage is. Because we build the store, we build the data your retention runs on: the metafields Klaviyo reads, the events it fires, the catalogue your flows depend on. Your programme is wired into a model we own, so the storefront and the lifecycle move as one system. That's email that runs on your store, not just beside it. What we do in Klaviyo: onboarding and migration, lifecycle flows, behavioural and predictive segmentation, deliverability, SMS, sign-up forms, and reporting against your own numbers, not just industry averages. Strategy, build, then ongoing management. Custom design runs through all of it. Storefront and emails, designed from scratch to match the brand, down to the detail most people only notice when it's missing. Our process is AI-enabled, end to end. We've built our own AI tools for brand audits, competitive research and account diagnostics, so the heavy analysis happens fast and our people spend their time on judgement. The depth of a large team, at the speed of a small one. We diagnose before we prescribe. The person who scopes your programme is the one who runs it. We're built for APAC. In your timezone, fluent across English, Mandarin, Bahasa and Malay, at home with multi-market Shopify Plus and the region's consent rules. A local partner for brands selling across Southeast Asia and beyond. We work with global brands, luxury and heritage names, and fast-growing DTC operators. Brands that notice when one email is off-brand. So do we. Already on Shopify or Shopify Plus, or building one? If you want a Klaviyo programme wired to the same foundations, run by people who understand both, let's talk.

Durante más de 10 años hemos trabajado con una premisa clara: la retención no es táctica, es estructura. Y se diseña desde el negocio, no desde la herramienta. Antes de plantear una estrategia de email, entendemos qué queréis vender, con qué margen, qué producto os interesa empujar, qué stock hay que mover y cómo se comporta vuestro cliente cuando compra... y cuando no lo hace. Porque el email no es un canal aislado. Es una palanca de crecimiento. Trabajamos con Klaviyo, sí. Pero la herramienta no es la estrategia. Lo que construimos son sistemas: automatizaciones conectadas entre sí, segmentación basada en comportamiento real y decisiones que responden al momento exacto del cliente. Y, si os somos sinceros, no queremos ser “la agencia de email”. Queremos ser el equipo que entiende cómo crece tu negocio y usa el email como palanca estratégica. Cuando encuentras un equipo que entiende tu marca y comparte tu ambición, lo notas. Y normalmente, ahí es cuando sabes que ya has encontrado tu agencia. 📨 e.martinez@maktagg.com

Goldsend is a retention marketing partner for ambitious ecommerce brands that want to turn more first-time buyers into loyal, repeat customers. We work with growing DTC brands that are investing heavily in customer acquisition but are not generating enough long-term value from the customers they have already paid to acquire. By connecting strategy, customer data and hands-on execution, we build retention systems that increase repeat purchases, strengthen customer relationships and improve lifetime value. Our team plans, builds and manages email, SMS and WhatsApp across the full customer lifecycle. This includes welcome and conversion journeys, post-purchase communications, replenishment, cross-sell, loyalty, customer win-back and ongoing campaigns. We also support segmentation, personalisation, testing, deliverability, performance reporting and lifecycle strategy. Unlike agencies that produce a strategy deck and leave clients to implement it, Goldsend works as an extension of the internal team. We identify where customers and revenue are being lost, prioritise the opportunities that will make the greatest commercial difference, and then build and run the programmes needed to address them. Brands can work with Goldsend through a focused strategy session, a comprehensive platform and lifecycle audit, or an ongoing Retention Operating System partnership. Every engagement is built around clear priorities, practical recommendations and measurable commercial outcomes. Goldsend is a Klaviyo Gold Partner with hands-on experience across Klaviyo, Braze and Customer.io. We primarily support ecommerce businesses generating between £1 million and £10 million in annual revenue, particularly brands in health, beauty, apparel, home and other categories with strong repeat-purchase potential. Our approach is commercially rigorous, straightforward and tailored to each brand’s customers, resources, technology and stage of growth. No generic playbooks or unnecessary agency theatre. Just smarter lifecycle marketing designed to help every customer relationship become more valuable over time.
