SMS marketing for small business: best practices and examples

Here is a number worth paying attention to: SMS messages have an open rate of around 98%. Compare that to email, which hovers between 20% and 30% on a good day. Text messages get read. Almost all of them. Almost immediately.

For small businesses, that kind of attention is gold. You are not competing with a crowded inbox or battling an algorithm. You are landing directly in someone's pocket, and they are reading your message within minutes of receiving it.

But that power comes with responsibility. Get SMS marketing right and it becomes one of the most effective channels in your toolkit. Get it wrong and you will annoy people, damage your reputation, and potentially break the law. This guide covers both sides.

Why SMS works so well for small business

The strength of SMS is immediacy. When you send a text message, it gets seen fast. The average response time for a text is 90 seconds. For email, it is 90 minutes. That difference matters when you are sending appointment reminders, time-sensitive offers, or follow-ups that need a quick response.

SMS also feels personal. A text from a business feels more like a message from someone you know than a marketing blast. That intimacy is why response rates are so much higher. People interact with texts differently than they interact with emails or social posts.

For local and service-based businesses in particular, SMS fills a gap that other channels cannot. It is perfect for the kind of short, time-sensitive, action-oriented communication that makes up most of your customer interactions.

Email is where you educate. SMS is where you activate. Use both, but know which job each one does best.

Staying compliant: the Australian rules

Before you send a single text, you need to understand the rules. In Australia, SMS marketing is governed by the Spam Act 2003 and enforced by the Australian Communications and Media Authority (ACMA). The rules are clear and the penalties for breaking them are serious.

Consent is mandatory. You must have explicit consent before sending marketing messages via SMS. Someone booking an appointment with you does not automatically give you permission to send them promotional texts. You need a clear opt-in, and you need to keep a record of it.

Identification is required. Every SMS you send must clearly identify your business. The recipient needs to know who the message is from. Use your business name as the sender ID whenever possible.

Opt-out must be easy. Every marketing SMS needs to include a way for the recipient to unsubscribe. "Reply STOP to opt out" is the standard approach. When someone opts out, you must honour it immediately. No delays, no extra messages, no "are you sure?" follow-ups.

Transactional messages are different. Appointment reminders, booking confirmations, and delivery notifications are not marketing. They are transactional messages, and they have different (less restrictive) rules. You can send these without marketing consent, as long as they are directly related to a service the customer has engaged with. But do not try to sneak promotional content into a transactional message. Regulators see through that quickly.

What to send via SMS (and what to leave for email)

SMS is not a replacement for email. It is a complement. Each channel has its strengths, and using them correctly means matching the message to the medium.

Use SMS for:

• Appointment reminders and confirmations
• Time-sensitive promotions (flash sales, last-minute availability)
• Review requests with a direct link
• Short follow-ups after a service
• Booking confirmations and changes
• Quick check-ins with active leads

Leave for email:

• Newsletters and longer content
• Detailed product or service information
• Welcome sequences with multiple pieces of content
• Invoices and detailed receipts
• Educational content and guides

The rule of thumb is simple. If the message is short, time-sensitive, and requires a quick action, use SMS. If it is longer, more detailed, or informational, use email.

Timing your messages

When you send an SMS matters almost as much as what you send. Get the timing wrong and even a good message will feel intrusive.

For appointment reminders, send the first one 24 hours before and a second one two hours before. This combination gives people time to reschedule if needed, while the second reminder catches the ones who forgot.

For promotional messages, business hours are safest. Between 10am and 7pm on weekdays tends to perform well. Avoid early mornings, late nights, and Sundays unless your audience has shown they are receptive at those times. Nobody wants a marketing text at 6am.

For review requests, send them one to two days after the service. Close enough that the experience is fresh, but not so immediate that it feels pushy.

Templates you can use today

Here are ready-to-use templates for the most common SMS marketing scenarios. Customise them with your business name and details.

Appointment reminder:
"Hi [name], just a reminder about your appointment with [business] tomorrow at [time]. Reply C to confirm or call us on [number] to reschedule."

Review request:
"Hi [name], thanks for visiting [business]. We would love to hear how it went. Leave a quick review here: [link]. It means a lot to us."

Promotional offer:
"[Business] flash deal: [offer details] this [day] only. Book now: [link]. Reply STOP to opt out."

Post-service follow-up:
"Hi [name], thanks for choosing [business]. We hope everything is going well. If you need anything, just reply to this message."

Re-engagement:
"Hi [name], it has been a while since your last visit to [business]. We would love to see you again. Book your next appointment here: [link]. Reply STOP to opt out."

The best SMS messages read like they came from a person, not a marketing department. Keep them short, warm, and useful.

Measuring your SMS ROI

Tracking SMS performance is simpler than most channels because the actions are direct and measurable. Focus on these metrics.

Delivery rate. The percentage of messages that actually reach the recipient. This should be above 95%. If it is lower, you likely have outdated phone numbers in your database that need cleaning.

Response rate. How many people reply to or click a link in your SMS. For appointment confirmations, you should expect 40% to 60%. For promotional messages, 10% to 20% is strong.

Opt-out rate. Track how many people unsubscribe after each campaign. A spike means something went wrong. Either the message was not relevant, the timing was off, or you are sending too frequently. Keep this below 2% per campaign.

Conversion rate. Of the people who clicked or responded, how many took the action you wanted? Booked an appointment, left a review, redeemed an offer. This is the number that connects your SMS efforts to actual revenue.

SMS marketing for small business works because it meets people where they already are: on their phones, ready to act. Respect the channel, keep your messages useful, stay compliant, and you will build a communication tool that consistently drives results.
