Classification of the feature
Shopify is expanding Shopify Messaging with the ability to create SMS marketing automations directly in the Shopify admin. This brings part of traditional marketing automation closer to the core of the store: triggers, customer data, and sending logic are now more embedded within the Shopify ecosystem instead of residing exclusively in external tools.
This is particularly relevant for shops that have so far used email automations, but send SMS only manually or via third-party providers. Especially in the D2C environment, SMS can make sense when timing is critical, for example with abandoned carts, back-in-stock notifications, or time-limited promotions.
What’s important, however, is putting it into context: SMS is not a replacement for email marketing and it’s also not a channel for just any kind of campaign. Direct delivery to the smartphone makes the channel highly attention-grabbing, but at the same time much more sensitive. Poor segmentation stands out negatively here much faster than with emails.
As of today, according to Shopify’s documentation, the exact availability of certain features depends on the country, store configuration, and messaging support.
What the feature is – and what it isn’t
The new feature enables automated SMS messages based on Shopify events or customer segments. This means messages can be sent not only manually, but also according to rules.
A typical process looks like this:
A customer puts a product in the shopping cart, leaves the shop, and after a set period of time automatically receives a short reminder by SMS.
Or:
A customer regularly buys certain consumable products and, after a realistic period of use, automatically receives a reminder to reorder.
The feature is therefore primarily a tool for transaction-related communication and repeat-purchase logic.
It is not intended, however, for sending large quantities of promotional messages indiscriminately. SMS works differently from email. Users tolerate far fewer messages, react more sensitively to irrelevant content, and unsubscribe more quickly.
Nor does Shopify Messaging replace a full customer data platform. Complex cross-channel journeys, advanced attribution models, or extensive AI-based personalization remain typical tasks for specialized systems.
Requirements & Data Basis
The most important point before any SMS automation is obtaining consent.
No marketing SMS should be sent without valid SMS consent. This is especially true in Europe, where data protection and advertising regulations are interpreted strictly. A customer must have demonstrably agreed to receive marketing SMS messages.
In practical terms, this means:
- Phone number must be saved correctly
- Consent must be documented
- Unsubscribing must be possible at any time
- Language and country logic must be taken into account
International shops in particular often underestimate the importance of data quality.
An example:
A phone number is being saved without an international country code. The system may then be unable to correctly identify or deliver to the recipient.
The language is just as critical. If a French customer suddenly receives a text message in German, it quickly comes across as spam.
Character sets also play a role. SMS messages that use Unicode characters, such as certain emojis or special symbols, can reduce the number of characters available. This directly affects the cost, because messages may technically be split into multiple SMS segments.
Before go-live, the following should therefore be checked:
- Which countries are supported?
- Which sender names are possible?
- How are opt-outs processed?
- What phone number formats are available?
- Which language is stored for each market?
How to use it concretely in the Shopify admin
The practical setup starts in the Shopify admin area, within the Marketing or Messaging sections.
The typical procedure is as follows:
First, SMS marketing is activated and linked with the necessary settings. These include, among other things, consent logic, supported markets, and, if applicable, shipping options.
After that, an automation is created.
First you define the trigger here. Common triggers are:
- cart abandonment
- Purchase completed
- Customer added to segment
- Product available again
Next, you specify when the message should be sent.
That sounds trivial, but it’s crucial.
A cart abandonment SMS sent after ten minutes often comes across as pushy. After two to four hours, it’s more likely that the user will see the message as a helpful reminder.
After that, the actual SMS text is created.
Important here:
SMS work better when they are extremely clear. Not a long marketing text, but a specific piece of information with a clear link.
For example:
“Your shopping cart is still waiting for you: [Link]”
This is followed by testing.
Before going live, teams should always check:
- Do links work correctly?
- Is the language correct?
- Are special characters displayed correctly?
- Is the SMS delivered in the correct country?
- Is the logout working?
Especially for larger shops, it is also advisable to have an internal test segment with different devices and countries.
Practice logic that determines costs and quality
With SMS, quality is determined not only by the content, but above all by the sending logic.
The biggest mistake many shops make: too many messages.
SMS is expensive compared to email. At the same time, acceptance drops quickly when customers receive several messages within a short period of time.
That’s why every automation should have a clear priority.
For example, if a customer has already received a shipping confirmation or support communication, an additional marketing SMS can quickly feel overwhelming.
Equally important is frequency control.
If X happens, then Y should only be triggered if the customer has not received any other SMS in the last few days.
Splitting is also relevant.
Long messages can technically be split into multiple SMS. This increases costs and often makes them harder to read. That’s why short messages usually work better.
Another point is deliverability.
Not every phone number is valid. Some countries have their own requirements for sender names or registrations. International shops should therefore test per market instead of rolling out the same logic globally.
Typical practical applications
Cart abandonment in mobile purchases
Especially on mobile devices, users often abandon the process shortly before making a purchase. A brief reminder a few hours later can be useful if there was already an intention to buy.
What matters here is restraint. A single reminder is usually more effective than several escalating follow‑ups.
Back-in-Stock Notifications
For products with high demand, SMS often works better than email because it gets more attention.
This applies especially to limited products, seasonal items, or sizes that sell out quickly.
Repurchase logic for consumable products
Shops that sell dietary supplements, cosmetics, or consumable goods can determine usage periods relatively precisely.
If a product typically lasts 30 days, it can make sense to send a reminder after about 25 days.
Reactivation of inactive existing customers
If customers used to order regularly but haven’t been active for a longer period of time, a single SMS can be a good idea.
What matters most is relevance. Without a specific reason, the message quickly comes across as arbitrary.
Text and template examples
Short text messages usually work better than long ones. Many shops try to cram too much information into a single message.
cart abandonment
“Your shopping cart is still saved: [Kurzlink]”
Back in Stock
“Your desired size is available again: [short link]”
Repurchase Reminder
“Time to reorder? You can find your product here: [Kurzlink]”
Note on character limits
The longer the message and the more special characters or emojis are used, the more likely it is that it will technically be split into multiple SMS messages. This can increase costs and reduce readability.
When it makes sense – and when it doesn’t
SMS makes sense when:
- the message is time-critical
- a purchase intention already existed
- mobile usage dominates
- Customer relationship already exists
- clear segmentation is possible
SMS makes less sense when:
- broad mass communication is planned
- there is no proper consent basis in place
- Products have little repurchase potential
- Customers rarely buy on mobile
- Teams do not have clear frequency control
A simple warning signal:
If the same message could just as easily be an email, an SMS is often unnecessary.
Mistakes to avoid
Too many messages
Several text messages within a short period of time can quickly come across as pushy. It becomes especially problematic when different systems are sending messages in parallel.
Poor segmentation
Not every customer should receive the same message. Without segmentation, relevance and deliverability often decline at the same time.
Texts that are too long
SMS messages are not a substitute for a newsletter. Long texts reduce readability and increase sending costs.
Missing language logic
International shops need clear language rules for each market. Using the wrong language quickly comes across as unprofessional.
No internal testing
Especially for larger shops, different countries, devices, and consent scenarios should be tested.
Technical implications for larger shops
As your shop grows, the technical requirements increase as well.
A central topic is data consistency.
When customer data is stored in parallel in Shopify, the CRM, the helpdesk, and external marketing tools, it’s easy for different consent statuses to arise. As a result, the same customer can be considered both “allowed” and “not allowed” at the same time.
Integrations also play a major role.
Before the rollout, the following should be clarified:
- Which systems are allowed to trigger SMS messages?
- Where is the primary source of consent located?
- How are cancellations synchronized?
- Which events trigger automations?
- Are there any overlaps with email flows?
In addition, larger shops should define governance rules.
For example:
- maximum number of SMS per week
- Approval processes
- Country rules
- Logging and Documentation
- Testing and rollback processes
Test cases are particularly important.
When a customer:
- Abandons cart
- still buys it afterwards
- receives an email in parallel
- is recognized in the wrong country
… the automation must respond in a way that can be understood.
Moving Primates Perspective
In projects with larger Shopify stores, a recurring pattern often emerges: teams think about copy and campaigns first, but consider shipping logic and data quality too late. Especially with international stores, problems often don’t arise in marketing itself, but with consent status, phone number formats, or missing frequency capping between different tools. It’s also typical that SMS are triggered in parallel from multiple systems, causing customers to receive duplicate messages. A practical solution is therefore centralized governance: clear responsibilities, defined sending rules per market, and a small internal test segment that runs through every new automation completely before rollout.
10-point checklist before shipping or go-live
- Is documented SMS consent available?
- Are phone numbers correctly formatted for international use?
- Has the correct language been checked for each market?
- Do unsubscriptions work correctly?
- Are frequency limits defined?
- Have all the links been tested?
- Are there overlaps with other marketing tools?
- Were different devices tested?
- Are test customers and internal approvals available?
- Is it clearly documented which teams are allowed to send SMS messages?
FAQ
How much does SMS marketing cost in Shopify?
According to Shopify’s documentation, the costs depend, among other things, on the country, shipping volume, and type of SMS. In addition, long messages or Unicode characters affect the actual sending costs.
What data do I need at a minimum?
At a minimum, you need a valid phone number and documented SMS consent. In practice, it’s also important to have language, market, and meaningful segmentation data.
When is SMS unsuitable?
When there is no clear relevance or time sensitivity. For general newsletters or broad discount promotions, email is often the more suitable option.
How often should you send text messages?
There is no universally valid number. In practice, however, users tolerate significantly fewer text messages than emails. Therefore, the frequency should be deliberately limited.
Can international shops use the same automation everywhere?
Usually not a good idea. Countries differ in language, consent rules, and delivery logic. International shops should review automations for each market.
Do you need to test SMS separately as well?
Yes. In particular, international shops should test different devices, number formats, languages, and consent scenarios before automations go live.
