Retention marketing, rebuilt

You can finally get personal with your customers.

Merzo reads each customer's engagement story — what they've said, what they bought, what they've ignored — decides the next best move to keep them engaged, and acts on it. Then it does it again. On autopilot, continuously, for each customer.

First for Shopify stores. 3 months free, then 50% off, locked in permanently.

The 1-on-1 problem

Great retention is one-on-one. It's also tough.

Only about a quarter of first-time buyers ever come back. Not because you're careless — because personalizing for thousands of people, across five channels, by hand, isn't realistic. So most teams fall back on segments: the standard 15% off code, a cross-sell out of nowhere, the same message on email and SMS within the hour. Customers notice — and what they notice is that you don't really know them.

Meanwhile, your actual flow logic looks like this
IF opened_email AND NOT clicked → send SMS
IF clicked AND NOT purchased → send discount code
IF purchased → wait 14 days, then upsell
IF no_response_30_days → move to "lapsed" segment
ELSE → do nothing, and hope
The shift

Merzo makes it happen.

Three signals a segment-based setup can't see — and exactly what Merzo does about each one.

The cross-sell that almost worked
Maya — skincare brand
The win-back that fires for everyone at once
Tom — coffee brand
The VIP who isn't treated like one
Aisha — streetwear brand

Priya bought the hero serum six weeks ago. She clicked Maya's moisturizer cross-sell but didn't buy — then DM'd the Instagram page yesterday asking if it works for sensitive skin.

Without Merzo

Clicked, didn't buy — bucketed with 400 others.

  • Generic discount email
  • Same treatment as the whole segment
With Merzo

Merzo sees her real pattern.

  • 7am email, her own open window
  • Replies on Instagram, where she just messaged
NEXT: Email at 7am — her own open window

How it works

Here's how Merzo pulls it off.

Merzo sits above the tools you already use — Klaviyo, Meta, whatever's already in place — doing four jobs, one continuously updating decision per customer. You review everything until you trust it, then let it run.

01
EmailSMSReviews → 1 profile

Signal unification

One ongoing conversation, not five disconnected events — purchase, engagement, reviews, and support, in a single live profile per customer.

02
EmailSMSWhatsAppSocial

Channel arbitration

Merzo picks the channel, message, and timing for each customer, automatically.

03
"New arrival alert 🌿 — meet your new favorite."

Brand-faithful content

Every message matches your brand voice, personalised to their history.

04
Email ✓SMS ✓WhatsApp ✓

Cross-channel delivery

Email, SMS, WhatsApp, and social — coordinated, never overlapping.

The promise

What actually moves.

The industry metrics that matter — engagement, retention, and advocacy — and the minimum lift you can expect across each one, from day one.

Common questions

Questions you might be asking.

Straight answers to what most Shopify owners want to know first. Still have one? hello@hoptroop.com

Is Merzo a Shopify app?

Yes. Merzo is built specifically for Shopify stores — it reads your store's customer, order, and engagement data to decide what each customer needs next, and connects to the channels you already use.

How is Merzo different from Klaviyo or a loyalty app?

Those are channels — they send whatever campaign you build. Merzo is the decision layer above them: it decides what to send, to whom, on which channel, and when, then hands off execution to the tools you already use.

Do I need to replace my existing email, SMS, or review tools?

No. Merzo adds an intelligence layer on top of Klaviyo, Judge.me, and similar tools. If you're missing infrastructure for a channel entirely, Merzo can handle sending, receiving, and tracking it directly instead.

How much does a Shopify retention app like Merzo cost?

$99–$399/month, based on your customer count. Early access includes 3 months free, then 50% off for life, locked in permanently.

What results can I expect from using Merzo?

Early access cohorts are targeting a minimum 15–20% improvement, at a baseline, across engagement, retention, and advocacy metrics — including repeat purchase rate, churn, engagement score, and referral rate.

Does Merzo work across email, SMS, WhatsApp, and social?

Yes. Merzo reads engagement across every channel a customer is active on, and decides which channel to use for the next message — automatically, per customer.

How does Merzo help reduce customer churn?

By building an individual repurchase rhythm for each customer instead of applying one fixed win-back window to everyone — flagging early signs of drop-off before a customer actually lapses, rather than after.

Is Merzo a good fit for small Shopify stores?

Yes — Merzo is built specifically for SMB ecommerce brands on Shopify, with pricing that scales with your customer count rather than enterprise-level minimums or contracts.

When can I start using Merzo?
