The best email marketing software that integrates with Shopify
Every email tool claims a Shopify integration. Most ship a one-way contact export or lean on a Zapier bridge that breaks the moment you need order data in an automation. We only ranked tools with a real, native, two-way connection — products, orders, checkout and browse events flowing both ways in real time — then tested how deep that sync actually goes. The difference decides whether abandoned-cart and post-purchase flows work.
The one criterion that decides this list is the depth of the native Shopify connection: real-time, bi-directional sync of products, orders and on-site events into segments and automations — not a nightly contact dump. We weighted integration depth above all, then ecommerce automation and value, and discounted everything that does not touch the store. See the full rubric →

Klaviyo
Best Shopify integration
The deepest native Shopify integration in the category, full stop. Products, orders, checkout and browse events sync in real time and bi-directionally, feeding predictive analytics, abandoned-cart, browse-abandon and post-purchase flows that actually fire on live store data. It is the most expensive option once you cross 5,000 profiles, and that is the honest cost of the best connection on the market.
Purpose-built for Shopify and the value pick. The native app syncs orders and events cleanly, bundles email and SMS in one automation, and the free tier is real. Segmentation on store data is a step behind Klaviyo and the brand carries less analytical depth, but for most stores the connection is more than good enough at a fraction of the price.
Its Deep Data Shopify integration is the real thing — order and abandoned-cart data flow into the strongest automation builder in the field, not a Zapier patch. The catch is that Deep Data requires the Plus plan, so the true entry price is $49/mo, and the tool is built for lifecycle marketing broadly rather than store mechanics specifically. Pick it when automation logic matters more than store-native dashboards.
After the 2019 split, Mailchimp rebuilt a native Shopify app, and it works — order sync, product retargeting, basic abandoned-cart. The sync is shallower than Klaviyo or Omnisend and store-data segmentation is more limited, but for a merchant already fluent in Mailchimp it is a reasonable, familiar path.
A native Shopify plugin syncs contacts and orders, and send-based pricing keeps a large store list cheap until you mail it. Automation and store-data segmentation are mid-tier, and the integration is solid rather than deep, but for a budget-conscious store the economics are strong.
Here to name the trap. Constant Contact lists a Shopify connection, but it is a shallow, largely one-way contact sync — no real-time order events, thin abandoned-cart, no live store segmentation. For a content-led brand it can serve; for a store that needs cart and order flows it leaves you blind to the data that drives revenue.
What counts as a real Shopify integration versus a fake one?+
A real integration is a native app that syncs products, orders and on-site events bi-directionally in near real time, so your segments and automations react to live store activity. A fake one is a nightly one-way contact export or a Zapier bridge that passes a few fields and breaks under volume. Klaviyo, Omnisend and ActiveCampaign Deep Data are real; a shallow contact-only sync is not.
Is Klaviyo worth the higher price over Omnisend?+
If store-data segmentation and predictive analytics drive real revenue for you, yes — Klaviyo's sync depth and modeling are a clear step beyond. If you mainly need reliable abandoned-cart and post-purchase flows plus SMS at a sane price, Omnisend delivers most of the value for a fraction of the cost. Most stores under roughly 5,000 contacts are well served by Omnisend; data-hungry brands graduate to Klaviyo.
Can I use ActiveCampaign with Shopify without Zapier?+
Yes. ActiveCampaign's Deep Data integration is native and passes order and abandoned-cart data directly, but it requires the Plus plan, so budget $49/mo as the real entry point. Choose it when you want the strongest automation logic and are willing to trade store-native dashboards for it.
Why is Constant Contact ranked last here?+
Because its Shopify connection is shallow and largely one-way. It can sync contacts, but it does not stream live order and checkout events, so the cart and post-purchase flows that drive ecommerce revenue have nothing to fire on. For a store, that is the wrong tool.
