Email automation for Shopify marketing

EmailOS runs email flows inside your Shopify admin, from welcome series to cart recovery, without leaving the store.

Marketing email flows

Trigger, wait, send. Pause, archive, or filter who enters.

Customer journeys and ops alerts in one place

Growing stores need lifecycle email without a heavy ESP, and ops still run on copy-paste.

Abandoned carts go quiet

Abandoned cart and abandoned cart email sequences stall when cart recovery lives outside the store.

Transactional email is not enough

Order receipts do not cover a welcome email, welcome series, winback email, restock reminders, or browse abandonment.

Ops still copy-paste alerts

Backorders, dropship, and wholesale orders still trigger manual staff emails instead of a flow.

EmailOS automates customer journeys and internal notifications from the same flow.

<Who_it_is_for />

Built for Shopify teams that want email in admin

For growing Shopify stores that want email automation without a heavy ESP. A practical Klaviyo alternative, more capable than Shopify's built-in email marketing for automated journeys.

A fit if you need

  • Welcome email, welcome series, cart recovery, post purchase email, browse abandonment, and winback email
  • Ops complexity: backorders, preorders, made-to-order, restocks, dropship, 3PL, wholesale
  • Everything inside Shopify admin, not a separate marketing dashboard

Not a fit if you need

  • SMS, popups, review collection, or list-growth forms
  • A standalone ESP with a separate marketing dashboard
  • A CLI inbox or an image-to-HTML converter. Those are different products.

<How_it_works />

Three steps from preset to live flow

Install the app, pick a template, and turn it on. Shopify events fire the sequence.

01

Pick a preset or start custom

Welcome, abandoned cart, browse abandonment, shipping, reactivation, and ops templates are ready to edit.

02

Design the emails

Drag blocks, pull in Shopify products and discounts, personalize with {{variables}}.

03

Turn the flow on

Shopify events and storefront tracking fire the sequence. Delays, filters, and segments control who gets what.

<Product_capabilities />

Flows, a visual builder, and email in Shopify

Email marketing journeys and operational alerts share the same triggers, filters, and send log.

<Automation_flows />

Build multi-step email flows: trigger, wait, send

Pause, archive, or filter who enters. Launch a Shopify cart recovery email flow, welcome series, or custom email flows for customers and staff.

Triggers & filters

Trigger on cart abandoned, orders, shipments, product views, or a schedule. Filter by consent, tags, spend, cart contents, location, and discount codes.

Ready-made presets

Start from marketing presets (welcome, cart recovery, browse abandonment, post-purchase, winback) or ops presets (backorder, dropship, wholesale, large-order alerts).

Staff routing

Staff steps can email up to 3 notify recipients instead of the customer, routed by product or customer tags.

<Visual_builder />

<Post_send_actions />

Automate what happens after an email sends

Optional steps after a send can update Shopify records or call external systems. Tag customers, orders, or products; append notes; set metafields; remove someone from a segment; or POST a webhook.

<Segments />

Reusable audiences with AND/OR rules

Build reusable audiences with AND/OR rules and except this customer exclusions. Flows can target a segment so the right customers enter each journey. Target by purchase history, location, tags, and email engagement.

<EmailOS_FAQ />

Questions merchants ask

Is EmailOS a Klaviyo alternative?
EmailOS is a Klaviyo alternative built for Shopify-native email automation: email flows, a visual builder, segments, and ops alerts. It does not replace a full multi-channel ESP with SMS, popups, and list growth.
Do I need to leave Shopify?
No. You install the app and run flows from the Shopify admin.
Can I send from my own domain?
Yes on Plus and Pro after DNS verification. Free trial uses the shared EmailOS sending domain.
What happens if someone buys after an abandoned cart email is queued?
Purchase and related events can stop recovery sequences so customers are not emailed for a cart they already checked out.
Can I email my warehouse or supplier instead of the customer?
Yes. A flow step can send to staff or supplier addresses (up to 3). Product-tag filters route backorder, dropship, and 3PL orders without tagging every order.
Is there a drag-and-drop editor?
Yes. Blocks, Shopify product and discount pickers, countdown timers, and HTML if you need it.
How is revenue attributed?
Last-touch: an email click in the 7 days before an order can be attributed to that email.
