The Ecommerce Email Marketing Agency for DTC Brands That Want Repeat Revenue
We design and run email and SMS programs for ecommerce brands - the lifecycle flows, campaigns, and segmentation that turn one-time buyers into repeat customers. Less batch-and-blast, more revenue you can predict.
Most Ecommerce Brands Leave Their Easiest Revenue in the Inbox.
Email and SMS should be your highest-ROI channel. When it isn’t, it’s almost always one of these reasons.
Your flows were set up once and never touched.
Welcome, abandonment, post-purchase - all running on defaults while your products, prices, and customers moved on.
You’re blasting your whole list.
Same email to every subscriber, so you wear out your best customers and train everyone else to ignore you.
Your only segments are “engaged” and “not engaged.”
No lifecycle, no behavior, no purchase history - so your messaging can’t match where someone actually is.
Campaigns go out, but nobody knows what’s working.
No testing, no real attribution, no read on which sends actually drive revenue versus noise.
SMS is either unused or annoying.
Either you’re leaving the channel on the table, or you’re sending blunt blasts that get you muted.
Deliverability is quietly slipping.
Inbox placement drops a little each month, revenue leaks with it, and nothing warns you until it’s bad.
Email & SMS, Built as One Revenue System.
We don’t run campaigns in isolation. Flows, campaigns, and SMS work together against one goal - more revenue per subscriber.
Lifecycle Flows
The automated backbone: welcome, browse, cart and checkout abandonment, post-purchase, win-back, replenishment - built and continuously optimized, not set-and-forget.
Campaigns & Calendar
A planned campaign calendar with real segmentation, so the right people get the right message instead of one blast to everyone.
SMS & Deliverability
SMS as a segmented channel that complements email, plus active deliverability and list health so your sends keep landing in the inbox.
Your Free Audit Is a Complete Gameplan, Not a Sales Call.
Most agencies sign you, then disappear for eight weeks to “audit” before they tell you anything. We do the opposite. Before you pay a cent - before you even decide - you get a full teardown of your account and the exact plan to fix it, built from your real numbers. Here’s what lands in your inbox.
A Full Unit Economics Analysis
We pull your real numbers from Shopify and Klaviyo - margins, breakeven, retention order by order, and the most you can spend to acquire a customer without losing money. You see exactly where the business makes money and where it leaks.
Every Growth Lever, Mapped
The full set of levers that move LTV - converting one-time buyers to subscription, cutting voluntary and failed-payment churn, reactivating cancellers, lifting subscription AOV. You see which ones actually move the needle.
A Prioritized Lifecycle Scorecard
A flow-by-flow benchmark of your current program - what’s working, what’s broken, what’s missing - scored against brands like yours and ranked by revenue impact. A number, and a reason.
The Complete Gameplan
One prioritized roadmap - which flows to fix, kill, or build, which subscriber segments to split out, and which subscription levers to pull, in order, with targets and trajectory. Not a 40-page deck. A plan you can start tomorrow.
All built from your live Klaviyo, Shopify, and subscription data - never a template.

Anyone can publish their own wins. These weren’t published by us. Klaviyo, Skio, Loop and others wrote up our clients’ results as their own customer success stories. Read them at the source.

The Founder Does the Diagnosis
George Kapernaros founded YOCTO to do one thing better than anyone else: turn DTC retention into a measurable system. He sits on the Klaviyo Partner Advisory Council, the Forbes Business Council, and the Fast Company Executive Board - and he personally runs the audit on every account before a single deliverable is complete.
