Shopify treats SMS consent as its own thing rather than a variation on email, and the detail is more useful than it sounds. A customer's SMS marketing state is one of a documented set that includes pending as well as subscribed and unsubscribed, so a half-finished opt-in is a state you can see rather than a gap. The phone number itself is stricter than an email address: it is stored in international format and the same number cannot be assigned to two customers, which quietly turns your list into something with a hard edge on it. And no phone number on the account means no message, whatever the consent record says.

The other native detail worth knowing is at checkout, where Shopify provides a consent checkbox component and documents that only the SMS marketing policy is supported by it. There is no equivalent for email. That makes checkout the one place where SMS opt-in is a first-class, platform-supported moment rather than something an app has bolted on, and it is worth asking any vendor whether they use it.

What to look for in a Birthday app

Where the opt-ins come from: Checkout, a popup, a keyword reply, a form: each produces consent of a different quality and a different volume. The valuable ones leave a record you can point at later, showing when and where somebody agreed. Ask what the app writes back to the customer record, because that is what survives if you ever change vendors.
The registration you will have to do yourself: Sending marketing texts means a sender your carrier recognizes, and that process, its paperwork and its wait, belongs to the messaging provider rather than to Shopify. Find out what the app requires of you before your first send, since this is where launches slip by weeks.
What a message actually costs: Per-message pricing, per-country rates, whether images or links cost more, and what happens to your bill when a campaign goes to the whole list are the numbers that decide this purchase. Compare them like a phone bill, not like a software subscription.
Whether replies reach a human: A text invites an answer, and some of your customers will send one. Two-way messaging, where a person can pick up the conversation, is the difference between a channel and a broadcast, and only some of these listings offer it.
Suites that also do email: Several results here are email platforms with SMS attached. That can be the right answer, since one contact record and one automation builder beats two. Judge the SMS half on its own merits though: sender setup, deliverability by country, and whether the flows treat a text as a text rather than a short email.

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 →
