WHY SMS UNDERPERFORMS

SMS Should Be Your Highest-ROI Channel. For Most Brands, It’s a Blunt Instrument.

Texting has the highest open rates in marketing - and the lowest tolerance for getting it wrong. When SMS underperforms, it’s almost always one of these.

PROBLEM 01▲ LEAK

You’re blasting your whole list.

Every number gets the same text, so you burn your best customers and push the rest to unsubscribe after one too many.

PROBLEM 02▲ LEAK

SMS and email don’t talk to each other.

They run as two separate channels firing at the same people, instead of one coordinated system - so you’re paying twice to annoy the same subscriber.

PROBLEM 03▲ LEAK

You’re barely collecting numbers.

No SMS capture in your pop-up, no checkout opt-in - so your list grows slowly and the channel never reaches the scale that makes it worth it.

PROBLEM 04▲ LEAK

Your only automated text is an abandoned cart.

No welcome, no post-purchase, no replenishment, no win-back, no shipping updates - the flows that actually drive repeat revenue aren’t there.

PROBLEM 05▲ LEAK

You’re worried about compliance, so you under-send.

TCPA, opt-in rules, quiet hours - the fear of getting it wrong keeps you sending too little, or sending blind and risking real penalties.

PROBLEM 06▲ LEAK

You can’t tell what SMS actually earns.

Costs add up per message, but with no real attribution you don’t know which texts drive revenue and which just cost you money and goodwill.

Recognize a few? That’s where the free audit starts.

WHAT WE DO

SMS & Email, Built as One Revenue System.

We don’t run SMS in a silo. Texts, emails, and flows work together against one goal - more revenue per subscriber, without wearing your list out.

FIG.01 - THE REVENUE SYSTEM R · P · S I SMS FLOWS INPUT 01 II CAMPAIGNS INPUT 02 III SMS INPUT 03 REVENUE PER SUBSCRIBER REPEAT REVENUE 3 INPUTS · ONE SYSTEM
INPUT 01I

SMS Flows

The automated backbone: welcome, cart and checkout abandonment, post-purchase, replenishment, shipping, and win-back - built to fire at the right moment, not all at once.

INPUT 02II

Campaigns & Segmentation

A planned SMS calendar with real segmentation, coordinated with email, so the right people get the right text instead of one blast to everyone.

INPUT 03III

List Growth & Compliance

SMS capture built into your pop-ups and checkout to grow the list, plus TCPA-compliant opt-in, quiet hours, and consent handling so you can send confidently.

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.

01
UNIT ECONOMICS

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.

02
GROWTH LEVERS

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.

03
SCORECARD

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.

04
THE GAMEPLAN

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.

FAQ

SMS Marketing Questions, Answered.

What does an SMS marketing agency actually do?
We design, build, and run your SMS program end to end - automated flows, a segmented campaign calendar, list-growth capture, and compliance - and coordinate it with email so the channel drives repeat revenue instead of burning your list.
Do you run SMS and email together?
Yes - as one system. SMS is treated as a segmented channel coordinated with email, so the two reinforce each other instead of hitting the same person twice with competing messages.
Will SMS annoy my customers or hurt my brand?
Only if it’s done badly. Done right - segmented, well-timed, and genuinely useful - SMS is welcomed, not muted. We send to the right people at the right moment, not blasts to everyone.
What about TCPA and compliance?
We handle compliant opt-in, quiet hours, and consent management so you can send confidently. Compliance is built into the program, not bolted on after.
We’re on Mailchimp / Omnisend / Listrak. Can you migrate us to Klaviyo?
Yes - it’s one of the most common ways brands come to us. We migrate flows, segments, and historical data on a deliverability-safe ramp, so you don’t lose sender reputation or revenue in the move.
How is pricing structured?
A monthly retainer, scoped in hours to what your account actually needs - not per-message or per-campaign pricing. We quote it after the free audit, once we know what’s broken.
Do you also run WhatsApp?
Yes - for UK, EU, and LatAm lists, where text messages underperform and Meta’s pause on US WhatsApp marketing doesn’t apply. Same Klaviyo canvas, same segments, same attribution. See our WhatsApp marketing agency service.
