How Studio KSL Grew Email and SMS from 16% to 61% of Total Revenue on Klaviyo

Turn email and SMS from an afterthought into a primary revenue channel. The brand had strong products, a loyal audience, and a complex ecosystem of one-time purchases, subscriptions, and memberships, but the retention layer was not built to monetize any of it. The goal was full lifecycle coverage: automation across the customer journey, behavior-based segmentation, and SMS as a net-new channel.

Email produced roughly 16% of total revenue with only two active flows. Automation revenue was effectively zero. Sends were sporadic, segmentation was minimal, and there was no SMS program at all. For a brand with subscriptions and a membership app, nearly the entire lifecycle was going unmarketed.

We took over the full retention channel: strategy, flows, campaigns, segmentation, and SMS. We rebuilt the automation layer from the ground up around how customers actually move through the ecosystem, from first purchase through subscription and membership, then layered a consistent campaign program on top. SMS launched as a net-new channel once the email foundation was producing.

Rebuilt the flow architecture from 2 flows to 20+ revenue-producing automations covering welcome, abandonment, post-purchase, subscription lifecycle, and winback. Implemented behavior-based segmentation across purchase and membership activity so engaged buyers, subscribers, and lapsed customers each get different messaging. Launched SMS from zero. Established a consistent campaign rhythm with monthly attribution reporting so the brand can see exactly what the channel produces.

Within a year, email and SMS grew from 16% to 61% of total revenue. Attributed revenue grew 14x, from $10.7K to $153K per quarter. Flow revenue went from near zero to $56K per quarter. SMS, which did not exist at the start, now contributes $8.5K per quarter as a growing channel. The engagement has expanded twice since the original scope.
