PAASE is a UK-based, Klaviyo Master Elite agency founded in 2019 and headquartered in Milton Keynes/Buckinghamshire. From the outset, we’ve specialised in helping eCommerce and D2C brands harness zero‑ and first‑party data to craft smarter, more personalised email and SMS journeys. As pioneers, we were the first UK agency to achieve Klaviyo Platinum Master status, and the first Elite Master partner headquartered in EMEA.

Our approach blends cutting‑edge AI with rigorous commercial focus. We design predictive segmentation and dynamic content workflows that adapt in real time—optimising send times, content, and customer experiences at every stage. Leveraging an Urgency‑Impact framework, we prioritise high‑ROI initiatives through iterative testing and AI‑driven automation, ensuring efficiency and relevance.

We form long‑term partnerships rooted in transparency, data‑backed decisions, and shared success. Whether delivering rapid revenue uplifts—such as a 233 % increase in automated revenue and 238 % more daily orders for Okanui—or building sustainable frameworks, our portfolio spans global brands across beauty, fashion, homewares, wellness, and more. With PAASE, Klaviyo clients gain a partner who merges technology, strategy, and commercial insight to fuel scalable growth.
