Getting SMS marketing right in Australia
Effective SMS marketing in Australia means treating it as a high-trust channel. It requires more than a short message—compliance, relevance, and a clear role within your wider marketing mix.
1. Start with compliance first
Before you think about messaging, automation, or conversion, start with the rules. ACMA says businesses sending marketing SMS must have consent, identify themselves clearly, and include an unsubscribe function that is easy to use. The unsubscribe request must be actioned within 5 business days, and the opt-out pathway must work for at least 30 days after the message is sent. This is the baseline for email compliance, too—if a customer cannot easily understand who is contacting them and how to stop future messages, the program is not built properly.
- Use express consent wherever possible
- Keep clear records of when and how consent was collected
- Identify your business in every commercial SMS
- Include a simple opt-out, such as STOP
- Make sure opt-outs are processed within 5 business days
- Review current ACMA guidance before launch
2. Be intentional about your SMS strategy
Email can carry richer storytelling, more detail, and more content variety, while SMS works better as a trigger, prompt, or accelerator. It is often strongest when it nudges action at a high-intent moment rather than trying to carry the full campaign on its own. That is why good programs pair short, urgent texts with broader journeys and SMS marketing strategies that define exactly when the channel should step in.
- Use SMS to support moments of urgency or immediacy
- Lead with one action, one message, and one CTA
- Avoid squeezing a whole campaign into 160 characters
- Let email or landing pages carry the heavier detail
- Reserve SMS for moments that benefit from speed
3. Build a quality opt-in list
The value of an SMS list is not size alone—it is permission quality. A smaller list of people who clearly understand what they signed up for will almost always outperform a larger, weaker list. This is especially important for small businesses that are trying to build trust early and cannot afford unsubscribes driven by confusion.
- Explain what subscribers are opting in to
- Offer a clear reason to sign up, such as early access or useful updates
- Set expectations on frequency from the start
- Avoid pre-ticked boxes or unclear language
- Clean your list regularly and remove stale contacts
4. Focus on audience segmentation
Mass SMS sendouts are rarely the smartest option. Because SMS is such a direct channel, relevance matters even more. Segment your audience by:
- Purchase frequency
- Average order value
- Recent purchase activity
- Lifecycle stage (for example, first-time customer or loyal fan)
- Engagement level
- Product interest
- Location
With accurate and up-to-date segmentation, you can match content to customer behaviour, not just demographic data. That makes messages feel useful instead of invasive, and it helps reduce unsubscribes.
5. Keep your messaging concise
Strong SMS copy respects the format. That means one clear message per send, phrased in a way that feels human, brand-aligned, and useful. In Australia, generic or overly automated copy can feel especially impersonal. AI can speed up ideation, but human judgement should shape the final message so the tone feels credible.
- Stick to one message and one action per SMS
- Put the key value up front
- Keep language clear, natural, and specific
- Avoid spam signals like all caps, cluttered punctuation, or overhyped claims
6. Get your timing and frequency right
Timing can shape how your messages are received. Send messages in local business hours where possible, and make sure the timing fits the message itself. A reminder or lunchtime offer should arrive when it makes sense for the customer. It also helps to keep frequency in check,
- Send in local time zones
- Stay close to business hours for promotional texts
- Match send time to message intent
- Start with a restrained cadence, such as 2-6 marketing messages per month
- Increase frequency only when performance and subscriber feedback support it

7. Use automation when you can
Automation can take pressure off your team while helping SMS marketing arrive at the right moment. It is most effective when used for trigger-based sends, such as order updates, reminders, abandoned cart follow-ups, and post-purchase check-ins.
- Use automation for messages triggered by customer actions or key moments
- Review each trigger, delay, and message before it goes live
- Keep transactional and promotional journeys clearly separated
- Remove customers from a flow once the message no longer applies
- Track clicks, replies, and conversions to keep improving over time
