Email revenue architects for replenishment brands

Your customers run out. Make sure they reorder from you, not from an ad.

We engineer email and SMS revenue for CEOs of subscription and replenishment brands doing $100K–$500K a month, with email under 15% of revenue.

  • Deliverability
  • Segmentation
  • Proven lift

Email revenue architects, not another agency selling copy and pretty templates.

Pay once for the build. After that, you only pay in months your email and SMS revenue beats its baseline.No lift, no fee.

Revenue engineers, not template makers.

We run retention on unit economics, not open rates.

Why now

Email got more valuable in 2026. It also got a lot harder.

Paid traffic is rented. Your list is owned. But the rules for reaching an inbox, and for proving what email earns, changed. Most brands and agencies never caught up.

Gmail now rejects, not just filters

Full enforcement of bulk-sender rules since November 2025. Unauthenticated mail can be refused at the server.

Outlook joined in

Since May 2025, Microsoft rejects non-compliant mail from domains sending over 5,000 a day.

Open rates stopped meaning much

Apple's Mail Privacy Protection inflates more than half of all opens. Reports built on opens are guessing.

Attribution isn't proof

Klaviyo itself says attribution doesn't prove causation. A holdout test does.

Generic AI costs trust

Klaviyo's 2026 research: only 13% of consumers fully trust AI. Emails built on your own customer data still earn.

Every re-buy you miss, you pay for twice

When a customer runs out and nothing reaches them, the reorder goes to whoever shows up in their feed next.

75%

had no signup popup. 972 of 1,302 Shopify brands doing $50K+ a month with Klaviyo installed, checked on their homepage.

14%

What we build

Pretty templates don't fix a spam folder.

The work that moves email revenue is the part most agencies skip. That is where we start.

What most email agencies sell

  • Templates and copy
  • The same newsletter to the whole list
  • One 30-day reminder for every product
  • Open rates and attributed revenue in the report
  • Your account, run in their name

What we engineer

  • Authentication, warmup and inbox placement before the first send
  • Segments by purchase cycle, product and engagement
  • Reorder timing per product, from your own order data
  • Incremental revenue from a holdout, plus LTV and cohorts
  • Everything built in your account. You own all of it

The engine. We do all of this for you.

  • Inbox firstSPF, DKIM, DMARC and BIMI on your sending domain, warmed up, and placement checked every month.
  • Your own audienceA popup that asks one question first, then collects email and phone, with email and SMS consent captured right.
  • Replenishment, timed per productReorder reminders set to when each product actually runs out, not a generic delay. Personalized, in your voice, never robotic.
  • Deep segmentationBy purchase cycle, product, subscription and engagement. Inactive subscribers suppressed to protect your domain.
  • One journeyEmail, SMS and retargeting fed from the same segments, from welcome to winback.
  • Proof, not attributionA locked baseline and a holdout group, so you see the revenue email created. LTV and cohort curves every month.

FAQ

Questions founders ask on the call.

How do you prove the revenue is real?

We lock a baseline before we start and keep a holdout group that never gets the new flows. The difference between the two is the revenue email created, not just what Klaviyo credits to it.

How does "pay only when it works" work?

You pay one fee for the build. After that, the monthly fee is charged only in months your email and SMS revenue is above the locked baseline. Numbers depend on your size; we share them on the call.

What exactly is the baseline?

Klaviyo-attributed email and SMS revenue from a normal 60 days before we start, locked on day one. Any month at or below it costs you nothing.

Do we have to switch platforms, or give up our account?

No. We build inside your Klaviyo account. You keep admin access and own everything we build, including if you stop working with us.

Why start with deliverability?

Gmail, Yahoo and Outlook now reject mail that isn't authenticated properly. Every flow and campaign after that depends on reaching the inbox, so it comes first.

What do you need from us?

Access to Shopify and Klaviyo, your brand assets, and one 30-minute kickoff. We handle the rest.

Let's see what your email should be bringing in.

30 minutes. We'll show you where your list leaks and what it's worth to fix it. 2 spots left for this month, because the founder runs every account.
