The honest part

Why most Shopify email programs underperform.

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.

⚠ The cost of waiting another quarter

Every month without a real retention system, you're paying for it.

Why Inbox Lab

Not another "email agency".

Most agencies sell sends. We sell repeat revenue. Here's the honest side-by-side.

Other agencies

  • Generic copy from a template library
  • Reused flows across every client
  • Weak or broken segmentation
  • No real A/B testing program
  • No strategy — just send more
  • Junior accounts running senior brands

The 5-step email profit system

A repeatable system, not an agency lottery.

The same framework we've used for Shopify brands from $300k/yr to $4M+/yr.

01

Strategy & Profit Architecture

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.

→ Profit-focused lifecycle map + KPI plan
02

Flow & Content Blueprint

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.

→ Visual flowcharts for every core sequence
03

Email Design System

A master design + reusable blocks, not random one-off creatives. On-brand, mobile-first, built to be scaled across hundreds of future campaigns.

→ Master template + ready-to-send designs
04

Implementation & Tech Setup

We build it all live inside Klaviyo. Triggers, splits, filters, custom properties, events, deliverability. QA'd on every device before a single send.

→ Fully implemented, tested, tracked flows
05

Testing, Launch & 2-Week Support

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.

→ Live system + post-launch optimization
What we do

Everything Klaviyo, nothing else. By design.

Klaviyo Migration

From Mailchimp, Omnisend, Yotpo. Lists, templates, flows and deliverability — moved cleanly without losing your warm reputation.

Account Audit

We tear apart your Klaviyo and your funnel. You leave with a Shopify-tailored roadmap. Credited back if you proceed.

Monthly Newsletters

Content plan, design, segmentation, send — 8 to 12 campaigns a month, A/B tested, operated by humans.

Flow Build & Optimization

Welcome, abandoned cart, browse, post-purchase, win-back, replenishment, loyalty. The full lifecycle, fully tested.

Responsive Template Design

On-brand, mobile-first, hand-coded for high deliverability and high click-through across every inbox provider.

SMS + Reviews

Two-channel orchestration with proper consent, compliance and frequency control. Klaviyo SMS and Reviews fully integrated.

Human operators · AI-resistant since 2017

The kind of email taste AI hasn't learned yet.

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.)

01

Every operator on the team has 5+ years inside Klaviyo. Not 5 months. Not a bootcamp. Five-plus years of real DTC accounts.

02

We've shipped 200+ email systems across beauty, supplements, fashion, food, hardware and outdoor. We know the patterns AI hasn't seen.

03

Strategists, designers, copywriters and Klaviyo engineers — separate humans, not one generalist 'figuring it out' in your account.

04

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.

Case 01 · DTC Beauty · Skincare

Maya — clean beauty brand on Shopify

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.

Recreation Outfitters — US outdoor retailer

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.

The guarantee

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.

From the clients

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 / yr

Strategic, 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 brand
Objection handling

Questions we've actually heard.

We already have email flows
Most brands do. The issue is that they're often generic, outdated, or not optimized for conversions. We audit what you have, keep what works, and rebuild what doesn't — so your flows actually drive revenue, not just 'look nice'.
How long does setup take?
Typically 4–6 weeks depending on project scope. The base Flow Setup is 3–4 weeks; Standard runs 5–7 weeks; Pro can stretch to 7–10 if we're building 10+ flows from scratch. Either way, you get a live timeline before we start.
Do you only work with Klaviyo?
Yes. Shopify + Klaviyo is our core specialization. We don't split focus across five ESPs. That deep focus is why we can guarantee things like a 40%+ welcome flow open rate.
Will this work for my niche?
We primarily work with beauty, apparel, wellness, supplements, and other DTC Shopify brands. If you're on Shopify and sell a product people buy more than once, email retention will work.
Do I need high traffic?
Not necessarily for flow setup. Even a modest list can see massive gains from proper welcome, abandoned cart, and post-purchase flows. That said, advanced optimization and A/B testing perform better with traffic volume — which is why we scale the program as you grow.
