What is bulk SMS (in Australia)?

Bulk SMS is a way to send one text message to many recipients at once, rather than sending each message individually. Australian businesses use bulk SMS for marketing campaigns, events, staffing and rostering, and many other kinds of alerts. Messages send from a web app or an API, and replies come back to the same place.

MASS TEXTING USE CASES

Why Australian businesses send bulk SMS

For many Australian businesses, SMS is the most direct line to customers, right there on the device in their pocket. It suits far more than one-off promotions, from building loyalty to reaching people fast when timing matters.

FROM SETUP TO SEND

How to send bulk SMS step by step

You do not need a technical team or training to send bulk SMS messages. From choosing a provider to replying to the first responses, setup takes minutes rather than specialist skills. These six steps cover the process end to end, whether you are texting 100 Australians or 100,000.

Pick a bulk SMS service that fits your message volume, your budget, and the tools you already use. In Australia, check that it supports Spam Act compliance and sender ID registration, too. See our guide to the best SMS providers in Australia.

Decide how your messages appear to recipients. You can send from a branded alphanumeric sender ID, or a dedicated business number that customers can reply to.

Decide who should receive this campaign, from your whole list to a single segment based on location or past purchases. Make sure everyone you add has opted in to hear from you. See our guide to Australian SMS marketing laws.

Compose your text and personalise it with merge fields, such as the customer’s first name. Add a clear opt-out line, and save it as a template to keep future sends consistent.

Send your campaign straight away, or schedule it for the moment your audience is most likely to act. Delivery reports show you what landed as it happens.

Replies come back to a shared inbox, not a single phone. Your team can pick up conversations, tag them, and follow up in the same thread.

RULES IN THE WORKFLOW

Stay compliant as you send

Automated opt-in and opt-out workflows help you meet Spam Act obligations on every mass text. The next section covers what the rules require.

AUSTRALIAN SMS LAW

Stay compliant with Australian SMS law

Sending marketing texts in Australia comes with clear legal duties, and they are not optional. Two rules matter most. They are the Spam Act and the SMS Sender ID Register, and here is what each one asks of you.

The Spam Act requires consent before you send, clear identification of who you are, and a working unsubscribe option in every message. These apply to commercial SMS sent to Australian numbers. Read the detail in our guide to SMS marketing laws in Australia.

Since July 1, 2026, sender IDs must be registered through a participating telco to display your brand name. Unregistered sender IDs now show to recipients as “Unverified.” See the rules on the ACMA website, and our step-by-step guide to registering.

Keep proof of consent, and remove anyone who opts out straight away. Sinch Engage handles unsubscribe requests automatically, so opt-outs stay off your next send.
