Klaviyo Agency · Supplements & CPG
Supplements are a replenishment business, and the email program has to be built like one: replenishment timing per SKU, subscription lifecycle, and the welcome economics that decide whether a first order ever becomes a second.

A supplement brand lives or dies on the second and third order, and the timing math is unforgiving: a 60-day supply reordered late is a churned customer who never decided to leave. Klaviyo's own consumables data shows repeat purchases typically lag the product's run-out window by 20 to 25 days when the email program does not manage the cycle. That gap is exactly what a replenishment system closes, and it is what generic agency playbooks built for apparel never touch.
Consumption-window math per product size, engagement-gated tails, and subscription cross-sell at proven repeat intent. The build is published.
Popup-to-first-order paths that protect margin instead of training discount-waiters. See the welcome build.
Dunning and failed-payment recovery, pause-instead-of-cancel saves, and subscriber-versus-one-timer logic across every flow and campaign.
Campaigns segmented by the outcome the customer bought: energy, sleep, gut, performance. This is what lets cadence scale without unsubscribes climbing.
The supplement content calendar, cadence tuned to engaged list size, and the compliance-aware copy constraints the category carries.
The peak-season ramp, flow adjustments, and offer structure per our published BFCM playbook for supplement brands.
Our supplement library is the deepest part of the published playbook: welcome, replenishment, winback, post-purchase, BFCM, and the benchmarks behind each, every stat cited to a verifiable source. Read how we think before you ever talk to us.
We review your flows, replenishment coverage, and subscription lifecycle against the published checklist and hand you a prioritized fix list.
Replenishment timing per SKU, the welcome economics, and the subscription lifecycle, in revenue-priority order.
Goal-segmented campaigns on the supplement calendar, testing, and quarterly cleanups.
The full lifecycle stack plus two category-specific layers: replenishment flows timed to each SKU's consumption window, and subscription lifecycle messaging including dunning. The complete list is in our flow stack guide.
The center of gravity shifts to lifecycle economics: converting one-time buyers to subscribers at proven repeat intent, saving failed payments, and offering pauses before cancels. Involuntary churn from failed payments is one of the largest silent leaks in subscription businesses, and most accounts we open have no dunning flow at all.
Yes. The replenishment mechanics apply to any consumable: coffee, snacks, personal care, pet. The timing math changes per category, and that math is the point.
The usual Shopify subscription stack: Recharge, Stay Ai, Skio, and Shopify's native subscriptions, wired into Klaviyo events for dunning and lifecycle messaging.
