Taking Email From 8% to 38% of Revenue — Without One Campaign to an Active Subscriber

Growplex sells hair regrowth on subscription — 67% of store revenue is Recharge auto-billing, the setup where lazy email wins by intercepting renewals. Over two years we took email from 8.29% of store revenue to 38.27% the honest way: campaigns never touched an active subscriber, and 20 lifecycle flows owned the billing cycle. $2.21M attributed in 2025 alone.

The Problem:

A Founder Doing Email Alone, on a Brand That Bills Itself

When we stepped in, Growplex was a roughly $130K-a-month brand running email in-house: ad hoc campaigns, no structured automation, the founder building every send himself inside Klaviyo. Attribution sat at 8.29%. And the structural trap was waiting — with two-thirds of revenue on Recharge auto-billing, the fastest way to grow the dashboard was to blast paying subscribers and let last-touch attribution claim their renewals. Fake growth, real churn. The honest job was harder: new customers, second purchases, and saved subscriptions.

The Strategy:

Only Count Revenue Email Actually Created

Every decision followed one rule: only count revenue email actually created. That meant excluding the people most likely to buy anyway — active Recharge subscribers and 40-day recent buyers — from every campaign, then building the full lifecycle ecosystem around the moments a subscription brand actually pivots on: the first order, the upcoming bill, the canceled subscription, and the one-time buyer who hasn't subscribed yet.

Campaigns Never Touch an Active Subscriber

Ex. Recent Buyers (40) & Active Subs rides on every campaign. A renewal that was going to happen anyway isn't campaign revenue — with the exclusion on, a third of campaign revenue came from first-time customers. Real acquisition, not renewal interception.

Put the Money Engine on the Billing Cycle

20 flows built around the subscription lifecycle — renewal reminders, Recharge nurture, subscription ascension, churn-reduction winback — because on a brand where 67% of revenue is recurring, the highest-leverage email moments orbit the bill, not the promo calendar.

Onboarding Segmented by Quiz Result

The site's hair-concern quiz feeds three separate welcome flows — Hairloss Prevention, Hairline Kit, Advanced Hair Kit — plus a 10%-off variant under continuous testing. Post-partum shedding and a receding hairline should never get the same first email.

The Execution:

20 Flows and 33 Campaigns, Aimed at the Billing Cycle

The designs below are the real sends. A month-by-month post-purchase journey that tells new customers the truth about the shedding phase. A subscription ascension sequence that sells the routine, not the bottle. A churn-reduction save. Education campaigns signed by the founder. Discounts stayed scoped: 10% for new subscribers, 20% to step into a subscription, 50% only to win back a canceled one.

Subscription Renewal Reminder Flow

The money engine: $325,224 in 74 days at $18.62 per recipient — 16.6% of all store revenue from one flow with 17,464 deliveries, timed to land before the Recharge bill.

The Month-by-Month Journey

An 8-email post-purchase arc, Month 1 through Month 6, that leads with honesty — increased shedding in the first 4 to 8 weeks is the formula working — then walks the follicle science, phase by phase, ending plain-text.

Subscription Ascension

Three emails that sell the routine after the first order: consistency education, customer before-and-afters with names and timeframes, and 20% off to make recurring the obvious choice. One-time buyers converting was its own lane: $32,723 from 19,919 deliveries.

Recharge Nurture and the 50% Save

Active subscribers get value between bills instead of promos — $143,768 at $4.53 per recipient. When a subscription cancels, a two-email save flow leads with the hair-growth cycle and closes with 50% off the first month back.
