Key takeaways
- iMessage marketing means reaching iPhone customers in a blue bubble with cart reminders, order news, offers and replies.
- Blue bubbles are iMessage between Apple devices; green bubbles are RCS or SMS, which a brand can already send to iPhones today.
- US consent rules for marketing texts are the right baseline: opt-in first, brand name, STOP, quiet hours.
- iMessage is coming soon to Kanal: a store will send the first iMessage, such as an abandoned cart reminder, with the same automations as on WhatsApp.
iMessage marketing means reaching customers in the Messages app on their iPhone, in a blue bubble: a cart reminder, an order update, a launch, a reply to a question. iMessage for business has long meant Apple's customer service channel, run from a support console. iMessage is coming soon to Kanal: a Shopify store will instead send the first iMessage itself, an abandoned cart reminder for example, and run the same automations it runs on WhatsApp. This guide explains what reaches an iPhone today, the US consent rules to follow, message examples, and how to plan for your iPhone customers.
Facts about Apple come from Apple Support and Apple's Messages for Business documentation, and the US rules from the CTIA Messaging Principles and the FCC rule at 47 CFR 64.1200, all read on October 19, 2026.
Blue bubbles, green bubbles: what reaches an iPhone
Apple Support explains that the Messages app sends three kinds of messages:
| Type | Bubble | Sent to | Notes from Apple |
|---|---|---|---|
| iMessage | Blue | Other Apple devices, over Wi-Fi or cellular data | End-to-end encrypted |
| RCS | Green | Apple and non-Apple devices | Needs iOS 18 and a supporting carrier; encryption depends on carriers |
| SMS/MMS | Green | Any phone | A carrier service, not end-to-end encrypted |
In 1, Messages sends iMessage, RCS or SMS/MMS; in 2, iMessage shows in a blue bubble.
A brand that sends SMS or RCS is already in the Messages app of its iPhone customers, in green. iMessage marketing is about the blue bubble: the same app, the format customers use with friends and family. For the consumer side, see what iMessage is and iMessage vs WhatsApp.
iMessage for business: the two approaches
| Apple Messages for Business | iMessage from your store with Kanal (coming soon) | |
|---|---|---|
| What it is | Apple's customer service channel in Messages | Messages sent from your Shopify store's data, like WhatsApp |
| How you connect | An Apple-approved Messaging Service Provider | The Kanal app on your Shopify store |
| What the customer sees | A business profile, without a phone number | Your messages in a blue bubble |
| Typical use | Support conversations handled by agents | Cart reminders, post-purchase flows, campaigns, AI agent replies |
Apple's channel is documented in our guide to Apple Messages for Business. For the technical side of sending iMessages, read our iMessage API guide.

Consent and US rules for iMessage marketing
Treat marketing iMessages like marketing texts:
- Opt-in first. The CTIA Messaging Principles and Best Practices say messages should be sent only after the consumer has opted in, with a clear call to action that names your brand and how to opt out.
- STOP works. Under the FCC rule at 47 CFR 64.1200, replies such as stop, quit, end, revoke, opt out, cancel or unsubscribe revoke consent, to be honored within ten business days.
- Quiet hours. The same rule bars telephone solicitations before 8 a.m. and after 9 p.m. at the recipient's local time; some states set narrower windows.
- Your brand name first, so customers know who is writing.
Our guide to SMS opt-in and consent covers these rules in detail, including what records to keep.
Plan for iPhone and Android customers together
Not every customer can receive iMessage. Apple Support notes that iPhones on iOS 18 with a supporting carrier can receive RCS, and that "some businesses can send alerts and updates on your orders" through it.
In 1, RCS needs iOS 18 and a supporting carrier; in 2, some businesses send order alerts and updates through RCS.
| Customer | Channel that fits |
|---|---|
| iPhone with iMessage on | iMessage on Kanal (coming soon); SMS or RCS in the meantime |
| Android with RCS | RCS, with your verified brand, product cards and buttons |
| Uses WhatsApp | WhatsApp, with a conversation if they reply |
| Any phone | SMS |
Measure each channel the same way: orders and revenue attributed to the send, against a holdout group, minus the cost of the messages. See our RCS messaging examples for what the green-bubble channel can show.
