Klaviyo Retention Agency
Most Klaviyo agencies sell sends. A retention agency sells the system underneath them: the lifecycle architecture, segmentation, and deliverability that decide whether a first order ever becomes a fifth. That system is our entire business, and we publish how we build it.

Retention is not a synonym for email. It is three layers that most accounts have in the wrong proportions, and the proportions are the whole game: flows generate nearly 41% of email revenue from just 5.3% of sends, yet most agencies spend most of their hours on the campaign layer.
The automated lifecycle: welcome, recovery, post-purchase, replenishment, winback, sunset. This is where retention revenue durably lives, built to our published flow stack standard.
Engagement tiers, buyer cohorts, and suppression logic. This layer decides what every send costs your sender reputation, and it is where most accounts silently leak.
The variable revenue on top, sized by engaged list and season per our cadence formula. Important, but only after the other two layers hold.
Every engagement opens with the same forensic pass, because underperforming Klaviyo accounts fail in predictable places:
Winback windows suppressing next season's buyers, welcome discounts leaking to existing customers, subscriber flows hitting one-time buyers.
Definitions built on inflated opens, engaged segments that stopped updating, and a sender reputation quietly paying for both.
Windows set generously, revenue double-counted across channels, and reporting that would not survive your CFO. We name the window on every number.
No replenishment timing, no dunning, no sunset. The flows nobody notices are missing until the audit, because their absence looks like nothing happening.
The center of our practice is DTC brands from roughly $1M to $20M+ on Shopify and Klaviyo: big enough that the retention layer moves real revenue, focused enough that architecture beats headcount. Deepest vertical playbooks: supplements, CPG and food-beverage, beauty, fishing and outdoor, leather goods, and home decor. If you primarily need paid acquisition or a production mill, we say so and point you at the right shop in our honest agency guide. The full service breakdown lives on the Klaviyo agency page.
The published-checklist audit: flows, segmentation, deliverability, attribution, ranked by revenue impact. The fix list is yours whether or not we build it.
Roughly 60 days on the architecture, in priority order from the audit. Flows need traffic to validate, so the sequencing is the craft.
Campaigns, testing, and quarterly cleanups per the maintenance SOP, judged at day 90 on flow revenue share and repeat rate with windows held constant.
An agency whose product is the lifecycle system (flows, segmentation, deliverability, and honest measurement) rather than a monthly volume of sends. The distinction matters because the automated layer generates an outsized share of email revenue, and it is the layer generic engagements neglect.
A campaign-first agency shows results fast and shallow: better calendars move numbers within a month. An architecture-first engagement is slower to show and far more durable: rebuilt flows compound with every future subscriber. We sequence architecture first because the other order leaks money the entire time.
We scope from the audit, so pricing reflects what the account needs rather than a package tier. For context, full-service retention retainers across the industry run from roughly $3,000 to $15,000+ per month; mid-market engagements typically land in the $6,000 to $12,000 band.
Campaign improvements inside a month, architecture results by day 90, because flows need send volume to prove themselves. Anyone promising a step change in month one is selling.
Run our own process on us: the agency evaluation guide with its scoring rubric, and the pre-hire account audit. We publish both precisely so you can.
