Email is one of the few marketing channels a small business actually owns. Your social media reach can change overnight and ad costs rise and fall, but a list of customers who asked to hear from you stays yours. This guide explains how email marketing for small business in Australia works in practice: how to build a list legally, which emails to send first, how to make sure they reach the inbox, and how to measure whether it is bringing in sales and bookings.
Why email still matters for small businesses
People who join your list have already shown interest. They bought from you, booked a job, asked for a quote or signed up on your website. That makes email a good fit for the things small businesses need most:
- Bringing past customers back for a repeat purchase or a service reminder
- Following up quotes that went quiet
- Recovering online shoppers who left items in their cart
- Announcing new products, seasonal offers or opening hours
- Building trust with helpful tips, so you are the first business people think of
Email also works alongside your other channels. Ads and search bring new people to your website, and email keeps in touch with them after the first visit. If you run paid campaigns, our guide to Facebook ads for tradies shows how ads and follow up fit together.
The rules: the Spam Act in plain English
Before you send a single marketing email in Australia, you need to know the Spam Act 2003 guidance from the ACMA. It applies to every business, big or small, and even if someone else sends the emails for you. The ACMA sets out three core requirements.
1. Get consent
You must have consent from each person before you send them marketing. The ACMA describes two types:
- Express consent is when someone knowingly agrees to receive marketing from you, for example by ticking a box on a website form, filling in a form, or agreeing over the phone or face to face. The ACMA calls this best practice.
- Inferred consent can apply in some cases where a person has an ongoing relationship with your business and the marketing is directly related to it. The ACMA notes that it is less reliable than express consent and does not cover sending marketing just because someone recently bought something from you.
Keep a record of when and how each person gave consent. Under the Spam Act it is up to you to prove it. You also cannot send an email asking for consent, because that email is itself a marketing message.
2. Identify yourself
Every marketing email must clearly show your business name and correct contact details. The ACMA suggests using your legal business name, or your name and ABN.
3. Make it easy to unsubscribe
Each commercial email needs a working unsubscribe option. According to the ACMA, unsubscribe requests must be honoured within 5 working days, must not cost a fee, and must not require the person to log in or create an account.
One more point that catches many businesses out: buying an email list does not give you consent. If you use a purchased list, you are still responsible for proving consent for every address on it. In practice, building your own list is safer and works far better.
How to build your list the right way
The best email lists are built slowly from people who genuinely want to hear from you. Simple ways to grow yours:
- Add a sign up form to your website. Put it in the footer and on key pages, and say clearly what people will receive.
- Offer something useful. A first order discount for an online store, a seasonal maintenance checklist for a trade business, or a free guide for a professional service.
- Ask at the counter or on the job. A tablet form in store or a tick box on your quote form is express consent you can record.
- Ask at checkout. Online stores can include a marketing opt in at checkout. Leave the box unticked so the choice is clear.
A website that captures leads straight into a CRM makes this much easier, because every sign up lands in one place with the date and source recorded. Our guide to a small business website with a CRM explains how that setup works.
The first emails every small business should set up
You do not need to send a newsletter every week to get results. Start with a handful of automated emails that run in the background and send at the right moment.
Welcome email
Sent the moment someone joins your list. Thank them, remind them what they signed up for, deliver any offer you promised, and tell them how often you will be in touch.
Quote follow up
For service businesses, a short email two or three days after sending a quote can prompt a decision. Keep it friendly and offer to answer questions.
Abandoned cart email
For online stores, a reminder to shoppers who added products to their cart but did not finish checking out. This is one of the most useful automations an ecommerce store can run. Our Shopify growth service covers this alongside other store improvements.
Review request
After a job is finished or an order arrives, ask happy customers for a Google review. Reviews help your local search visibility, as we explain in our local SEO guide.
Reminder and win back emails
Service reminders, such as an annual air conditioner service or a dental check up, and a gentle message to customers who have not bought in a while, both bring people back without any ad spend.
Getting your emails into the inbox
An email that lands in spam earns nothing. Gmail and Yahoo have both tightened their rules for senders. Google's email sender guidelines require all senders to set up SPF or DKIM authentication and to keep spam rates reported in Postmaster Tools below 0.3%. Senders of more than 5,000 messages a day to Gmail accounts must also set up DMARC and support one click unsubscribe. Yahoo publishes similar sender best practices.
Even if you are a small sender, it is worth following the full set of rules from day one:
- Send from your own domain, such as [email protected], not a free Gmail or Hotmail address.
- Set up SPF, DKIM and DMARC records for that domain. Your email platform will give you the exact records to add.
- Only email people who opted in, and remove addresses that bounce.
- Keep a visible unsubscribe link in every marketing email.
- Send consistently. Sudden bursts of email from a quiet domain can look suspicious to inbox providers.
Writing emails people actually open
Subject lines
Be clear rather than clever. Tell people what is inside, keep it short enough to read on a phone, and avoid misleading wording. The ACCC warns businesses against false or misleading claims, and that applies to emails as much as ads.
One email, one goal
Every email should have a single main action: book now, shop the new range, leave a review, or reply with a question. One clear button works better than five competing links.
Write like a person
Small businesses have an advantage here. A short email from the owner, written in plain language, often feels more genuine than a polished template from a big brand.
Design for mobile
Many people read email on their phone. Use a single column, large text and a button big enough to tap easily.
What to measure
Open rates have become less reliable as email apps change how they load images, so focus on numbers closer to revenue:
- Clicks on the main link or button
- Bookings, sales or enquiries that came from each email
- Unsubscribes and spam complaints, which tell you when you are sending too often or to the wrong people
- List growth from your website forms each month
When your email platform is connected to your website and CRM, you can see which emails turned into real jobs or orders, not just clicks.
Common mistakes to avoid
- Adding people to your list without their consent
- Buying or scraping email lists
- Hiding or breaking the unsubscribe link
- Sending from a free email address with no domain authentication
- Only sending discounts, so customers learn to wait for the next sale
- Setting up automations once and never checking them again

Frequently asked questions
Is email marketing worth it for a small business?
For most small businesses, yes. It reaches people who already know you, costs little to run once it is set up, and automated emails like welcome, quote follow up and review requests keep working in the background.
Do I need permission to send marketing emails in Australia?
Yes. Under the Spam Act 2003 you need consent from each person before sending them marketing, and every email must identify your business and include a working unsubscribe option. The ACMA website explains the rules in detail.
Can I buy an email list?
The ACMA warns that you are still responsible for having consent for every address on a list you buy or use. Building your own list from people who opted in is safer and usually performs much better.
How often should a small business send emails?
Start with automated emails that send at the right moment, then add a regular campaign once or twice a month. Watch your unsubscribe rate and adjust if it starts to climb.
Why are my emails going to spam?
Common causes are sending from a free email address, missing SPF, DKIM or DMARC records, emailing people who did not opt in, and high complaint rates. Fixing domain authentication is usually the first step.
