Klaviyo That Recovers
Revenue Your Store Is Leaving Behind.

In Klaviyo, Flows (formerly called Sequences) are automated email or SMS sequences triggered by a specific customer behaviour or event — a purchase, an abandoned cart, a browse of a specific product category, a birthday date. They run automatically whenever the trigger condition is met. Campaigns are one-time sends to a defined segment — your weekly email newsletter, a flash sale, a new product announcement. Most of a brand's Klaviyo revenue comes from Flows because they intercept customers at high-intent moments. Campaigns build the relationship at scale. A complete Klaviyo programme needs both — Flows to capture revenue at key moments, Campaigns to maintain engagement and drive repeat purchase at scale.

Some flows produce results immediately — an abandoned cart flow that goes live today will generate revenue from the first day if your store has cart abandonment traffic. Welcome series, post-purchase, and browse abandonment flows also show results within days. Longer-term flows like win-back and VIP programmes take 30-60 days to accumulate enough entries to produce statistically meaningful results. Segmentation improvements and deliverability work show results more gradually — typically 4-8 weeks for deliverability improvements to show in inbox placement rates, and 8-12 weeks for the impact of better segmentation to appear in campaign open and click rate trends. Overall, most clients see measurable revenue improvement from Klaviyo within 4-6 weeks of a full programme build going live.

Yes — Shopify Plus and Klaviyo is our most common ecommerce stack combination. The Klaviyo-Shopify integration gives us access to detailed product, order, and customer data that powers personalisation — recent orders in post-purchase flows, browsed products in browse abandonment, category affinity in welcome series, and AOV and purchase frequency in RFM scoring. We configure the integration to capture every Shopify event Klaviyo can receive, ensure the product catalogue is syncing correctly for dynamic product recommendations, and map Shopify customer tags to Klaviyo custom properties for segmentation. We also work with WooCommerce, Magento, BigCommerce, and custom Shopify implementations.

Yes — SMS compliance (TCPA in the US, GDPR in the UK/EU) is essential before sending any commercial SMS. We configure Klaviyo's SMS consent capture correctly — ensuring subscribers provide explicit consent at a compliant opt-in point (typically checkout or a dedicated SMS opt-in pop-up), that the consent language clearly describes what they are signing up for, that unsubscribe is handled correctly (STOP keyword processing), and that quiet hours are set to prevent sends during legally restricted times. We also ensure your SMS list is separate from your email list — SMS consent does not grant email consent and vice versa — and that your consent data is retained with the timestamp and source for audit purposes.

Klaviyo does not calculate RFM scores natively — it needs to receive them as custom properties on the customer profile. We set up an RFM calculation that runs on your Shopify or ecommerce platform order data (or via a data warehouse), calculates R (days since last purchase), F (total number of orders), and M (total spend) scores for each customer, maps those scores to one of eight segment labels (Champions through Lost), and syncs those labels to Klaviyo as custom properties via the Klaviyo API. We then build Klaviyo segments based on those custom properties. The calculation runs on a schedule — typically daily — so segment assignments update as customer behaviour changes. This approach is more reliable than trying to approximate RFM using Klaviyo's native predictive analytics features, which are limited to Klaviyo's own data model.
