It won't suggest what you already have
Every specialist looks at your site before suggesting anything. What you already have doesn't come up and, if something slips through, you tap «I already have it» and it won't come back.
Don't let the first order be the last.

- Automated emails that are missing or have stopped.

What is the Email & customers specialist?
It's the Argos specialist for repeat purchases. It reads your Klaviyo flows and campaigns alongside your Shopify orders and tells you which email is missing, which one underperforms and who to write to before they forget you. Without burning out your list on discounts.
- Reads
- Klaviyo and your Shopify orders
- Reviews your store
- Every 6 hours, after each Klaviyo read
- Who does it
- You, in Klaviyo, step by step, or Empact
From the first order to the second.
What happens between one purchase and the next, with its number and what you can do about it.
Reads your emails and your orders
Flows, campaigns and list health in Klaviyo, matched with who buys and who comes back in Shopify.
Hands you the play
The flow that's missing or has stopped, the campaign that doesn't sell or the customers going cold, with the data that backs it.
You do it, it gets measured
In Klaviyo, step by step, or by asking Empact. After 28 days you know whether it moved its metric.
Sample store · fictitious data
Orders waiting in your list.
Three plays from Vinoteca Olivares, the sample store. None of them needs more discounts; all of them, better aim. With your store, they come with your numbers.
What it sees
The abandoned cart flow recovers 90 of 4,260 carts in 28 days (2.1%), with a single email.
Klaviyo · 28 days

Who does it
You, in Klaviyo, step by step. Or you ask Empact.
What it sees
27,369 profiles, 38% of the list, haven't opened an email in months and still get every campaign.

What to do
A two-email re-engagement campaign and, for anyone who doesn't respond, stop sending to protect delivery for everyone else.
Who does it
You, in Klaviyo. Or you ask Empact.
What it sees
No flow is triggered by an order, and a new customer takes 11 months on average to buy again.
Klaviyo · Shopify
What to do
A three-email post-purchase flow: thank you, how to enjoy it and what to try next.
Who does it
You, in Klaviyo. Or you ask Empact, who writes it in your brand voice.
Vinoteca Olivares is the demo's sample store: its numbers are fictitious. In your dashboard, you see yours.
Your email and your customers. In one view.
What Klaviyo shows you on one side and Shopify on the other, together, with the play on top.
Flows that are missing or have stopped
Welcome, abandoned cart, post-purchase, win-back: if one is missing or has stopped sending, it tells you. It checks the live flow, not a draft copy.
Campaigns that get opened and don't sell
Campaigns with opens but no orders behind them, with what they really sold in Shopify.
Customers going cold
The ones who bought once and haven't been back in a while, so you can write to them before they forget you.
Cohorts, month by month
In Customers, what share of each month's buyers comes back at 30, 90 and 180 days, and what each one is worth.
Your list's health
Deliverability, the profiles that no longer open and how much you rely on discounts to sell by email.
Your discount policy, respected
No coupon it suggests goes beyond what you've set in your discount settings.
First, it looks at your store. Then, it measures.
No play goes out blind, and none is called a success without its numbers.
What doesn't work comes back
Every play says which metric it moves and is measured 28 days before against 28 days after. If nothing changes or it gets worse, it returns to your to-dos on its own, with a note of when it was done.
Klaviyo on one side, Shopify on the other. Or together.
Shopify already has cohorts and returning customers, and Klaviyo has its own reports. What's missing is connecting them, and someone telling you what to do.

How to find out why customers don't come back on Shopify.
A short guide to do it yourself, with what you already have. It works with or without Argos.
See how many come back
In Shopify Analytics, the returning customer rate and the cohort report: what share of a month's buyers comes back in the months that follow.
Check the four basic flows
Welcome, abandoned cart, post-purchase and customer win-back. If one is missing, or hasn't sent in weeks, start there.
Judge campaigns by what they sell
Opens are misleading: some inboxes count them even when nobody reads. Look at each campaign's orders and sales.
Look after your list
People who haven't opened in months hurt delivery for everyone else. Try to win them back and, if they don't respond, stop sending.
Don't lean on discounts for everything
If every campaign carries a coupon, your customers learn to wait. Try content, new arrivals or restocks.
Matching Klaviyo with your orders by hand takes an afternoon every month. Email & customers does it every 6 hours and leaves what moves the needle most in My week.
See Email & customers in the demoWhat it doesn't do. Nor will it, without you.
Email & customers tells you what to do with your list. This is out of scope, or up to you.
- It doesn't send emails. Nor does it touch your Klaviyo flows: it tells you what to change, and you or Empact do it.
- Klaviyo only. If you use another email tool, it sees your Shopify customers and orders, but not your flows or campaigns.
- It doesn't design your emails. It tells you which email is missing and what it should include; the design and final copy are up to you or Empact.
- Few orders, little signal. Cohorts and repeat purchases need history: with a very new store, it tells you so.
Questions about Email & customers.
What does Email & customers need?
Klaviyo and your Shopify. With Klaviyo it sees your flows, your campaigns and your list's health; with Shopify, who buys, who comes back and what each customer is worth.
Does it send emails or change my flows?
No. It suggests the play with its data and the steps for Klaviyo. You do it, or ask Empact from the play.
I use a different email tool. Will it work for me?
Partly: you see your customers, repeat purchases and cohorts from Shopify, but it only reads flows and campaigns from Klaviyo.
What are cohorts?
Your customers grouped by the month of their first purchase. They tell you what share of each group buys again and when, so you know whether repeat purchases are improving or slipping.
Will it flood my list with discounts?
No. It also tracks how much you rely on discounts, and no coupon it suggests goes against your discount policy.
How often does it review my email?
Every 6 hours, after each Klaviyo read. If a flow stops sending, you get an alert; the rest goes to My week.
