Done-for-you Klaviyo retention system for Shopify brands. Flows, campaigns, segmentation, optimization — built and run by senior humans (no GPT cosplay).
Klaviyo is the most powerful tool in DTC — and the most misused. The difference between a 5% and a 35% email channel isn't the platform. It's the operator.
That's exactly what we fix.
Most agencies sell sends. We sell repeat revenue. Here's the honest side-by-side.
The same framework we've used for Shopify brands from $300k/yr to $4M+/yr.
Before any pretty emails, we map how email actually makes you money. Lifecycle map, KPI plan, segments, triggers, and the stack to track it all.
The money flows on paper first. Welcome, abandoned cart, browse, post-purchase, win-back, loyalty, bounce-back, cross-sell — with logic, timing and angles for every email.
A master design + reusable blocks, not random one-off creatives. On-brand, mobile-first, built to be scaled across hundreds of future campaigns.
We build it all live inside Klaviyo. Triggers, splits, filters, custom properties, events, deliverability. QA'd on every device before a single send.
Soft-launch to a small segment, monitor deliverability, then go full send. Two weeks of free hands-on monitoring + a 30-day revenue report after launch.
From Mailchimp, Omnisend, Yotpo. Lists, templates, flows and deliverability — moved cleanly without losing your warm reputation.
We tear apart your Klaviyo and your funnel. You leave with a Shopify-tailored roadmap. Credited back if you proceed.
Content plan, design, segmentation, send — 8 to 12 campaigns a month, A/B tested, operated by humans.
Welcome, abandoned cart, browse, post-purchase, win-back, replenishment, loyalty. The full lifecycle, fully tested.
On-brand, mobile-first, hand-coded for high deliverability and high click-through across every inbox provider.
Two-channel orchestration with proper consent, compliance and frequency control. Klaviyo SMS and Reviews fully integrated.
Sure, ChatGPT can write a subject line. Can it look at your Klaviyo dashboard, spot why your post-purchase open rate dropped 11 points last Tuesday, and ship the fix by Friday? Yeah. Didn't think so.
(We feed it coffee. It's fine.)
Every operator on the team has 5+ years inside Klaviyo. Not 5 months. Not a bootcamp. Five-plus years of real DTC accounts.
We've shipped 200+ email systems across beauty, supplements, fashion, food, hardware and outdoor. We know the patterns AI hasn't seen.
Strategists, designers, copywriters and Klaviyo engineers — separate humans, not one generalist 'figuring it out' in your account.
Weekly Loom reviews, real Slack replies under an hour, a U.S.-friendly schedule. You'll know the names of the people in your inbox.
Real Klaviyo accounts. Real attribution. Names lightly anonymized — full references and dashboards on request.
Inherited a Klaviyo with 3 generic flows and a 9% open rate. We rebuilt the lifecycle from welcome to win-back, added a popup A/B test, and rewrote every email around real buyer objections. Email went from 7% → 31% of monthly revenue.
Big catalog, low repeat rate, almost zero segmentation. We built browse, cart, post-purchase, replenishment and win-back, plus a behavioral segmentation layer. Result: a top-3 revenue channel, not an afterthought.
Luxury buyer, long consideration cycle, very high AOV. We split the lifecycle by intent (research vs. ready-to-buy), redesigned the master template to match the brand, and ran weekly newsletter A/B tests. Email is now the #1 owned channel.
Our best Welcome Flows hit 55%+. We set 40% as the floor — a conservative number we're confident any healthy eCommerce brand can hit. Plus 2 weeks of free post-launch monitoring: anything that breaks, we fix at no cost.
They rebuilt our entire Klaviyo from the ground up. Email went from 8% to 34% of revenue in four months. Single best agency call we've made.
Founder, beauty DTC brand · $1.8M / yrStrategic, technical, and they actually care about the numbers. Weekly Loom reviews, real Slack replies — no other agency we've worked with does that.
Head of Growth, supplements brand30-minute call. We review your Klaviyo live and leave you with a written opportunity map — whether you hire us or not.
No pitch deck. No 12-month contract. Just useful work.
