From an order in Shopify to the customer's WhatsApp reply in under 10 seconds. Here is what the data flow looks like.
An example from Chatarmin's customer base: a customer orders a pet food subscription for 84 euros in a Shopify store at 14:23. Within 7 seconds the order reaches Chatarmin as a webhook, is matched with her WhatsApp profile and triggers the post-purchase flow. At 14:23 she receives a WhatsApp confirmation with a tracking link. Three days later comes the shipping update, 14 days later the review request. After 60 days, based on how long the food lasts, the restock reminder follows. One system, all based on Shopify order data, not a single manual step.
"There are over 10,000 customers we currently can't reach by email."
— Shopify brand with 50,000+ euros in monthly revenue, from a Chatarmin sales call
More than 1,100 sales calls with e-commerce brands show that Shopify is by far the most used integration at Chatarmin. The reason is the low implementation threshold rather than the marketing promise. WhatsApp marketing for Shopify is up and running in a few minutes, with no developer, no CSV import and no nightly sync job. That is why brands with 50,000+ euros in monthly revenue end up with Chatarmin: the setup costs less than the sales call that precedes it.
70% of all Shopify carts are abandoned before checkout. WhatsApp reaches the share that email misses.
As soon as a customer enters email and phone number in the Shopify checkout and closes the tab, Shopify sends a checkouts/update webhook to Chatarmin. If the phone number belongs to a WhatsApp profile with a valid opt-in, the abandoned cart flow starts after the configured delay (30 minutes, 2 hours or 24 hours). The message is personalised automatically: first name, image of the most expensive item in the cart, direct checkout link with pre-fill, and optionally a discount code from the Shopify discount system.
From Chatarmin's customer base: abandoned cart flows on WhatsApp convert 3 to 10 times better than by email. An example at an average cart value of 60 euros and a 5% conversion rate: 100 messages cost 11 euros in Meta fees and bring in 300 euros of revenue, a ROI of 27:1. Three A/B variants run in parallel, so you can systematically optimise copy, image and discount logic.
"WhatsApp messages get read. The open rate is 85%, while winback emails often land below 15%. And unlike email, a WhatsApp message appears right on the lock screen."
— Summary from several Chatarmin sales calls
The WhatsApp flow runs alongside your Klaviyo abandoned cart rather than replacing it. You can send on both channels (WhatsApp 30 minutes after abandonment, email after 2 hours), or use Klaviyo lists for email non-openers and trigger WhatsApp only where the email is still unopened after 48 hours. Your Customer Success Manager sets up either option with you during onboarding.
The thank-you page widget turns 20 to 40% of buyers into WhatsApp subscribers. Your list grows passively with every order.
Right after a purchase, the customer's attention is at its peak: they have just spent money, they expect a confirmation and shipping details, and they are ready to open a channel for it. Chatarmin places an opt-in widget with a clear promise ("Shipping updates via WhatsApp") on the Shopify order confirmation page. Between 20% and 40% of buyers sign up. For a store with 1,000 orders a month, that is 200 to 400 new WhatsApp subscribers, without active acquisition and without ad spend.
Once a buyer has opted in, Chatarmin handles the entire post-purchase communication on WhatsApp. Order confirmation within 10 seconds of the webhook. Shipping update with a tracking link as soon as Shopify sets the fulfilment status to "shipped". Delivery confirmation once the carrier webhook reports "delivered". Review request 14 days after delivery. Optionally a cross-sell or restock reminder based on product category and usage time. Every step is fed with Shopify order data and shows open rate, click rate and attributed revenue in the dashboard.
"Shipping updates on WhatsApp reduce support requests by up to 70%. The customer gets the information proactively, before they even ask."
— From Chatarmin's customer base
Treating WhatsApp for Shopify purely as a marketing channel misses half its value. Every buyer who opts in through the thank-you page widget is not only a recipient for future campaigns but also a support contact who no longer needs to email "Where is my order?". If you also use Chatarmin for customer service (armincx by Chatarmin), both use cases run through one inbox: marketing campaigns from your Shopify stack and support requests from the same channel. That saves 2 to 4 service tickets per order on average.
Three workflows that come straight out of your Shopify data.
The widget on your Shopify order confirmation page invites buyers to your WhatsApp channel, and they confirm by double opt-in right in the chat. 20 to 40 percent of buyers sign up there, which means up to 400 new contacts at 1,000 orders a month.
As soon as Shopify marks an order as "shipped", the update goes out with a tracking link. When the carrier reports "delivered", the delivery confirmation follows, and 14 days later the review request.
For supplements, cosmetics, coffee or pet food, Chatarmin reminds customers to reorder once the product's typical usage time is up, with a direct link to the product in your store.
Customers who haven't ordered in 60, 90 or 120 days aren't lost revenue. With the Shopify integration, Chatarmin automatically identifies inactive customers based on last order date. A winback flow via WhatsApp reactivates them with a personalized offer or an exclusive discount code.
Shopify itself provides the basis: the date of the last order, order frequency and lifetime value per customer. That lets you stage the flow, for example a reminder after 60 days, an offer after 90 days and a discount code from the Shopify discount system after 120 days. Anyone who buys in between drops out of the flow automatically.
Restock reminders complement this approach: if you sell consumables (supplements, cosmetics, pet food, coffee), Chatarmin sends an automatic repurchase reminder after a defined interval. The interval is based on the product's average consumption period.
The Shopify integration delivers all the data you need for meaningful segmentation: purchase history, order frequency, cart value, product categories, tags. In Chatarmin, you can define VIP segments such as customers with a lifetime value above 200 EUR or customers with 3+ orders.
These segments receive their own WhatsApp flows: early access to new products, exclusive discounts, personal messages. VIP customers feel valued, purchase more frequently and recommend your brand.
48% of Chatarmin customers use Klaviyo in parallel. That's no coincidence. Shopify provides the shop data, Klaviyo manages email marketing and Chatarmin handles WhatsApp. All three systems sync bidirectionally.
How it works together: Klaviyo segments (VIP, cart abandoners, buyers of specific product categories) are directly available in Chatarmin as audiences for WhatsApp campaigns. Email addresses collected in the WhatsApp welcome flow automatically sync back to Klaviyo. Both lists grow in parallel, without cannibalization.
A concrete use case: Klaviyo sends an email campaign. After 48 hours, all non-openers automatically receive a WhatsApp follow-up. Conversion of the non-opener group increases by 15-25%.

Meta charges 11 cents per marketing conversation in Germany and around 5 cents in Austria and Switzerland. Chatarmin passes these costs on 1:1, with no mark-up on the message fee.
For a Shopify store you can run the numbers on your own data. The cart recovery example above shows the lever: 100 reminders cost 11 euros and, at an average cart value of 60 euros and a 5 percent conversion rate, bring in 300 euros of revenue. The same logic applies to winback and restock, using the order value of your existing customers. Shopify provides the numbers, and the Chatarmin dashboard shows per flow whether the maths works out.
Messages inside an open 24-hour service window are free. If your customer messages you after placing an order, the shipping updates in that window carry no Meta fee.

Everything you need to know.
The Chatarmin Shopify integration works with all Shopify plans, from Basic to Plus. All core features are available regardless of plan: abandoned cart flows, post-purchase, shipping updates, revenue attribution, segmentation and VIP flows. Shopify Plus additionally allows a checkout opt-in checkbox directly in the checkout process. All other opt-in methods (pop-ups, Thank-You-Page, QR codes) work with any plan.
Chatarmin attributes every purchase to the triggering WhatsApp campaign. You see cost per message vs. generated revenue per campaign in the dashboard.
Yes, Shopify, Klaviyo and Chatarmin sync bidirectionally. Klaviyo segments (VIP, cart abandoners, buyers of specific product categories) are directly available in Chatarmin as audiences for WhatsApp campaigns. Email addresses collected in the WhatsApp welcome flow automatically sync back to Klaviyo. Both email and WhatsApp lists grow in parallel, without cannibalization.
No. Subscribers overlap only 30 to 40 percent. Strongest combo: retarget email non-openers via WhatsApp.
Meta charges 11 cents per marketing conversation in Germany and around 5 cents in Austria and Switzerland, and Chatarmin passes that on 1:1. Whether a flow pays off shows up in the dashboard, right next to the Shopify revenue attributed to it.
An abandoned checkout through the checkouts/update webhook, a new order, the fulfilment status "shipped" and the carrier's delivery notification. On top of that come time-based triggers such as the date of the last order for winback or the usage time for restock.
The strongest option is the widget on the order confirmation page, with a sign-up rate of 20 to 40 percent. Mobile pop-ups, QR codes in the parcel and, on Shopify Plus, the checkbox right in the checkout add to that. Phone numbers from Shopify orders alone are not enough for marketing messages, which need a separate WhatsApp opt-in.
No, both run in parallel. Either WhatsApp after 30 minutes and email after 2 hours, or WhatsApp only for customers who have not opened the email after 48 hours. You set this up together during onboarding.
Yes. Orders, products and customer data flow between Shopify and Chatarmin in real time in both directions. WhatsApp events such as an opt-in or an order placed through a flow land directly in the Shopify customer profile.
