Shopify sends email itself, and rather more capably than this category implies. Its own tool comes with a free monthly send allowance that resets each month and does not roll over, and it already runs the automations sold hardest elsewhere: abandoned cart, abandoned checkout, browse abandonment, a welcome series, win-back and birthday. Abandoned checkout sends do not even count against the allowance. Capture is a separate free tool, which is not installed by default, and that is why plenty of merchants never find it.

So the useful question is narrower than which email app. What the paid platforms add is one flow spanning email, SMS and push rather than three tools that each know half the story, deeper segmentation, and connections to everything else you run. Those are real advantages. They are also the vendors' own claims rather than anything the platform documents, and they are worth weighing against a free tool that already covers the common cases.

What to look for in a Kalviyo app

Capture and sending are two different products
Part of this category only collects addresses and hands them to something else to send. Part of it is a full sending platform. Both describe themselves as newsletter apps, and buying the first while expecting the second is the most common mistake made here.
Do the arithmetic on what you actually send
Work out your list size times your sends per month before reading any pricing page. A great many stores never exceed the free allowance, and the ones that do usually know it. This is a ten-minute calculation that decides the whole question.
Consent belongs to the customer record
The opt-in level, when it was given and where it was collected are stored against the customer in Shopify, not inside the app, which means the legal basis survives you switching platforms. Check the app writes all three properly, because an app that only marks somebody subscribed has left you with less than you think.

What does the Built for Shopify badge mean?

Built for Shopify
Built for Shopify is the highest level of recognition Shopify awards an app. To earn the badge, an app must meet Shopify's standards for safety, performance, ease of use, and proven usefulness: it cannot slow down the admin, storefront, or checkout, must integrate seamlessly into the Shopify admin, and must demonstrate quality through installs, reviews, and ratings over time. When comparing similar apps, preferring ones with the badge is a safe default. Learn more about the Built for Shopify badge →

The rankings on these pages are Shopify's own organic search results; we never edit them, including for our own apps.
