The Best Email Marketing Shopify Apps

Introduction

Email is the only marketing channel you own outright, and most stores still treat it as an afterthought.

Ad costs rise, algorithms shift, and social reach evaporates, but a subscriber list keeps working whether or not you are spending.

This guide covers the best email marketing apps on Shopify by job, from list growth to automated flows to cart recovery, with ratings pulled straight from the Shopify App Store.

By the end you will know which app fits your stage, and when upgrading is worth the cost.

Email marketing is really three jobs

Most merchants install one app and expect it to do everything.

In practice, email splits into three distinct jobs.

List growth captures emails through popups and forms. Automated flows send the right message at the right moment, like abandoned cart or welcome sequences. Campaigns are the newsletters and promotions you send on purpose.

Some apps cover all three. Others do one job exceptionally well and cost far less.

Start by naming which job is currently broken.

Shopify Messaging, the free native starting point

Shopify's own Shopify Messaging is where most stores should begin, because it is built in and costs almost nothing.

It sends automated messages for welcome emails, abandoned cart reminders, and standard occasions, with your brand styling applied automatically.

There is no separate platform to learn and no integration to maintain.

Its limits are real. Segmentation and automation are basic compared to dedicated platforms, so it will not carry you forever.

Best for new stores proving that email works before paying for a bigger tool.

Klaviyo, the deep data platform

Klaviyo is the default choice for growing stores that want serious segmentation and automation.

Its Shopify integration is the deepest available, syncing store data in near real time so every message reflects current behavior. It supports email, SMS, and WhatsApp, with over 117,000 brands using it alongside Shopify.

Now the honest part. Klaviyo sits at a 4.6 star rating across roughly 2,860 reviews, noticeably lower than its rivals, and the recurring complaint is cost.

Merchants report steep price increases as their lists grow, with some describing renewals well above what they originally signed up for.

Best for stores with enough order volume that better targeting clearly pays for the bill.

Omnisend, the multichannel middle ground

Omnisend answers a simple question: how much of Klaviyo do you actually need?

It bundles email, SMS, and push notifications into one workflow builder, with pre-built ecommerce flows for cart abandonment, browse abandonment, and post-purchase.

For most stores, that covers the retention motions that matter without the configuration overhead or the pricing surprises.

It holds a 4.8 star rating across roughly 2,950 reviews and is free to install, rating higher than Klaviyo on the App Store.

Best for stores that want strong automation and SMS in one place without enterprise complexity.

SendWILL, for list growth first

SendWILL Popup Email Marketing is the most reviewed email app in the category, and it earns that through focus.

It grows your subscriber list with email popups and sends newsletters, doing the list growth job cleanly rather than trying to be a full platform.

It holds a 4.9 star rating across more than 7,100 reviews, is completely free, and carries the Built for Shopify badge.

If your list is small, no amount of clever automation will save you, which makes this the right first install.

Best for stores that need subscribers before they need sophisticated flows.

Pop Convert, for on-brand popups

Pop Convert is the other list growth heavyweight, with more than 8,300 reviews at 4.9 stars and the Built for Shopify badge.

It builds popups, banners, and free shipping bars that match your store's design instead of fighting it.

The distinction from SendWILL is emphasis: Pop Convert leans into banners and promotional bars alongside popups.

It offers a free plan, so testing costs nothing.

Best for stores that want polished capture without a heavy platform.

Brevo PushOwl, for pay-per-send economics

Brevo PushOwl combines email, push notifications, and SMS, with pricing that suits large lists sent to infrequently.

Where most platforms charge by contact count, pay-per-send models mean a big dormant list does not quietly drain your budget every month.

It carries a 4.8 star rating across more than 1,870 reviews, with a free plan available.

Best for stores with large customer databases that send campaigns a few times a month.

Wiz and the AI flow builders

Wiz AI Email Marketing represents the newest shift in the category: skipping manual flow building entirely.

It generates abandoned checkout recovery, welcome emails, winback flows, and back-in-stock alerts automatically, writing and designing the emails itself.

It holds a perfect 5.0 star rating across 213 reviews, is Built for Shopify, and offers a free plan.

The caveat is scale. A few hundred reviews is far less proof than Klaviyo's thousands, so test it on one flow before trusting your whole program to it.

Best for time-poor merchants who want flows running without building them by hand.

Abandoned Cart Email Marketing

Uppush Abandoned Cart Recovery narrows in on the highest value flow in ecommerce.

It handles abandoned checkout recovery with pay-as-you-go pricing, so you pay for what you send rather than a monthly seat.

It carries a 4.9 star rating across 149 reviews, is Built for Shopify, and offers a free plan.

Cart recovery alone often justifies an email tool, since those shoppers already told you what they wanted.

Best for stores that only need recovery and do not want a full platform.

Also worth knowing

Mailchimp remains viable at 4.8 stars across roughly 1,260 reviews, and makes sense if your team already knows it, though its Shopify-specific flows are weaker than Klaviyo's or Omnisend's.

Shopify Forms is free and handles capture, though its 4.4 star rating across 648 reviews is the lowest of the native tools.

Seguno is worth a look for Shopify-native simplicity. Shopify's own case study on Clay Imports reports a 30 percent lift in conversion on sample orders using it.

Where email stops and partners begin

Email works because it reaches people who already know you.

The harder problem is reaching people who do not, which is where paid ads get expensive fast.

An affiliate program solves that differently, letting creators and loyal customers introduce your brand and earn only when a sale closes.

Affilitrak is a Shopify affiliate marketing platform built for that, with a core plan that is free, and it pairs naturally with email since your best affiliates are often already on your list.

How to choose without overpaying

Start with the broken job, not the biggest brand.

If your list is small, install a capture tool like SendWILL or Pop Convert first. If cart abandonment is the leak, Uppush or Wiz fixes it cheaply.

Only move to Klaviyo or Omnisend when segmentation depth will genuinely convert to revenue, and model the cost at your projected list size before you commit. Shopify's Help Center covers the native tools you already have.

Watch pricing that scales with contacts, since a growing list can quietly turn a cheap tool expensive.

Conclusion

The best email app is the one matched to the job you actually need done today.

Begin with Shopify Messaging to prove the channel, grow the list with SendWILL or Pop Convert, recover carts with Uppush, and graduate to Omnisend or Klaviyo only when the data depth pays for itself.

Then remember that email talks to people who already found you, while affiliates go find the ones who have not.

So look at your last campaign honestly: are you emailing a list you built on purpose, or one that just happened to you?
