🇺🇦 Andriy Boychuk

Top 1% Email Marketing Expert

I help DTC leaders grow revenue through retention-led lifecycle systems across owned channels.

Email sits at the core.
SMS, WhatsApp, push, and other channels support it with purpose.

Flowium drives LTV growth, repeat purchases, and lower churn by building lifecycle strategies first, then activating channels only where they improve ROI.

We design retention systems, not campaigns.
Strategy stays fully in-house.
Execution follows the lifecycle, not the other way around.

Flowium is an Elite Klaviyo Partner trusted by 1,000+ ecommerce brands.

Typical outcomes include 30 to 50 percent of total store revenue driven by owned channels.

My approach is structured and repeatable.
Audit the lifecycle.
Fix foundations.
Build flows.
Layer channels.
Test weekly.

If you lead growth at a DTC or Shopify brand and want more from the customers you already have, let’s talk.

NO, I CAN'T PROVIDE AN AUDIT BECAUSE MOST “KLAVIYO AUDITS” ARE USELESS

The lifecycle ecosystem is full of noise: Some say send more. Others say send less. Some say discount. Others say never discount. Try SMS. Try WhatsApp. Fix UGC. Fix loyalty. Add AI. Everyone has an opinion.

And most teardown-style audits make the chaos worse. They focus on tactics, not strategy. They tell you: You’re missing a block in a flow. Your popup could be better. You should send more campaigns.

None of this meaningfully shifts LTV, AOV, or retention for a brand doing real revenue. Founders don’t need 80 small optimizations, they need the 3–5 strategic moves that materially change their unit economics.

That’s why YOCTO created the Strategy Activation™ model: A first-principles, math-driven way to uncover the retention levers that actually move the needle.

HOW A STRATEGY ACTIVATION™ WORKS

1. We ask a few targeted questions about your goals and unit economics.
2. If we believe there’s meaningful upside, we sign an NDA and get temporary access to your lifecycle tech stack (Shopify, Klaviyo, subscription platform, etc.).
3. A few days later, you receive a fully mapped strategy built using the same methodology we apply to category-leading brands.

YOU'LL WALK AWAY WITH:

1. Your highest-leverage retention opportunities - ranked, justified, and tied to the three pillars that mathematically determine LTV

2. A clear plan to increase LTV, strengthen subscription economics, and fix repurchase gaps - without adding noise or unnecessary tactics

3. LTV:CAC modeling quantifying the potential upside so you know exactly what each lever is worth

If you only look at email through dashboards and flows, you’re looking through a keyhole.You’re optimizing what’s visible… while missing the broader system shaping customer behavior.

On January 15th, I’m sitting with Daniel Shnaider CEO of Warmy to break down "The Email Keyhole Problem" - how brands mistake partial visibility for understanding, and how to bust open the door to real leverage.
