In 2026, over 75 percent of businesses use SMS marketing, and 65 percent plan to increase their texting budgets this year. The global industry is worth roughly $17 billion. Yet most brands report disappointing results from the channel. The problem is not SMS itself — it is that most marketers have imported their email playbook into a medium that operates on completely different rules.
The brands winning at SMS are not the ones with the biggest lists. They are the ones that treat every text message like what it actually is: a direct line into someone’s pocket. Here is what separates the ones getting results from the ones burning through subscriber goodwill.
The Uncomfortable Truth About Your SMS List
Email trained marketers to think that bigger lists equal better results. So they chase subscriber volume, run “text WIN to 12345” campaigns that inflate their numbers with low-intent contacts, and then blast those lists with generic offers every week. The result is predictable — opt-out rates climb, deliverability suffers, and the channel slowly dies.
Your SMS list is not an asset if the people on it do not want to hear from you — it is a slow-motion opt-out queue.
Research from Omnisend shows that segmented SMS campaigns consistently outperform bulk sends on conversion rate — often by a factor of three or more. The top three reasons consumers say they opt in to brand texts are appointment reminders (76 percent), order tracking (61 percent), and promotion alerts (59 percent). Notice what those have in common: they are all useful in a specific moment. Nobody signs up to be “kept in the loop” with weekly blasts.
The brands making SMS work in Australia have figured out something counterintuitive: list quality crushes list size, every time. A smaller, permission-based list of genuinely engaged subscribers will outperform a bloated database on every metric that matters.
Why SMS Plays by Different Rules Than Email
When someone gives you their phone number, they are handing you something more personal than an email address. Nearly 74 percent of consumers check their text notifications within five minutes. Compare that to email, where open rates hover around 20 percent on a good day. SMS is not competing with 47 other messages in an inbox — it is sitting on a lock screen, front and centre.
That immediacy is SMS’s superpower, but it is also why the tolerance for irrelevance is so much lower. A promotional email you do not care about gets deleted. A promotional text you do not care about feels like an intrusion. Three of those in a row and the customer opts out — permanently.
This is the fundamental mistake most SMS marketing strategies make. They optimise for reach when they should be optimising for relevance. Every message needs to pass a simple test: would the person receiving this be glad they got it?
What Does a Good SMS Marketing Strategy Actually Look Like?
It starts with consent that means something. Under Australia’s Spam Act 2003, you need express or inferred consent before sending commercial texts. But legal compliance is the floor, not the ceiling. The brands getting the best results are transparent about frequency at sign-up (“You’ll hear from us 2-3 times a month with exclusive offers”), deliver on that promise, and make opting out effortless.
With iOS now classifying unsaved numbers as “Unknown Senders” and filtering them into a separate folder, brands that have not built genuine trust with their subscribers are essentially sending messages into a void. The permission-based approach is not just ethical — it is the only one that still works technically.
Segment ruthlessly, then segment again
If you are sending the same text to your entire list, you do not have an SMS strategy — you have a loudspeaker. At minimum, segment by recency of purchase, product category affinity, and engagement level. A loyalty member who shops weekly should get a different message at a different time than someone who bought once six months ago.
Platforms like Trudy from Trevor Services automate this by analysing purchase patterns and triggering contextually relevant messages. The difference between “Hey, 20% off everything this weekend!” and a personalised restock reminder based on someone’s actual purchase history is not just personalisation. It is the difference between being useful and being noise.
Write like a human, not a marketing department
You have 160 characters. There is no room for corporate speak. The best SMS campaigns read like a message from a friend who happens to know about a good deal. Short sentences. One clear action. No “Dear Valued Customer.”
And stop putting “DO NOT REPLY” at the end of your texts. Two-way messaging is one of SMS’s biggest advantages over email. Let customers reply to ask questions, confirm bookings, or give feedback. In 2026, 42 percent of businesses say chatbots and virtual assistants are their top SMS priority, specifically because conversational messaging drives higher engagement than broadcast.
Timing is strategy, not logistics
When you send matters as much as what you say. The data shows mid-morning and early evening on weekdays tend to perform best, but “the data” is an average — and averages hide the insights that matter.
AI-driven send-time optimisation now analyses individual subscriber behaviour to determine when each person is most likely to engage. It is the difference between scheduling a blast for 10am Tuesday because a blog post told you to, and sending each message at the moment that person is most receptive. If your SMS platform cannot do this, it is already outdated.
The Metrics That Actually Matter
Most brands track SMS delivery rates and call it measurement. That is like measuring a restaurant’s success by how many people walked past the front door.
The metrics that tell you whether your SMS marketing strategy is working are revenue per subscriber (not per message — per subscriber, per month), opt-out rate per campaign (this is your canary in the coal mine), and conversion rate by segment. If you are not tracking these three, you are flying blind.
Trevor Services builds real-time dashboards that surface these metrics alongside your other campaign channels, so you can see exactly where SMS fits in the broader engagement picture — and where it is pulling more weight than you expected.
Where SMS Is Heading Next
Rich Communication Services (RCS) is bringing richer media into the native messaging app — images, carousels, interactive buttons — without requiring customers to download anything. As Australian carriers expand RCS support, the line between SMS and app-based messaging will blur. The brands that have built strong, permission-based subscriber relationships now will be positioned to take advantage. The ones still blasting generic texts to bloated lists will wonder why nobody is opening their messages anymore.
The direction is clear: SMS is becoming more personal, more conversational, and less tolerant of lazy marketing. The brands that thrive will be the ones that treat every text as something a real person will read in a real moment — and make it worth their time.
If your SMS channel is underperforming, the problem probably is not the channel. It is how you are using it. Talk to Trevor Services about building an SMS strategy that earns attention instead of burning goodwill.
