Email marketing

Why it matters

Winning a new customer costs far more than selling again to an existing one, and email is the cheapest way to make that second sale happen. A customer who hears from you usefully every month is far more likely to come back and to refer than one who hears nothing until they happen to need you. Email also compounds: a list of a few hundred engaged local customers is a marketing asset that keeps producing regardless of what social platforms or search engines do. The rules around consent are strict, though, and getting them wrong can mean penalties from the Australian Communications and Media Authority, so the foundation has to be right.

Consent and the Spam Act

Commercial electronic messages in Australia, including marketing emails and SMS, are governed by the Spam Act 2003 and enforced by the Australian Communications and Media Authority (ACMA). The Act has three requirements. You must have the recipient’s consent, which can be express (they ticked a box, filled in a form, or told you) or inferred from an existing business relationship where the message is relevant to it. Every message must clearly identify your business and how to contact you. And every message must contain a working unsubscribe facility, with requests honoured within five business days.

In practice this means: never buy or scrape lists, keep a record of how and when each person consented, make the unsubscribe link easy to find, and act on it promptly. Pre-ticked boxes and consent buried in terms and conditions are poor practice and risky. Reputable email platforms handle the identification and unsubscribe mechanics for you, but the consent is your responsibility. If your business is covered by the Privacy Act, the Australian Privacy Principles also govern how you collect and use the personal information on your list.

Build the list from people who already know you

The best list is built from customers and genuine prospects, not strangers. Add a clear invitation to every natural touchpoint: the enquiry form, the quote, the invoice, the counter, the booking confirmation, the follow-up call. Say plainly what they will get ("a monthly email with seasonal tips and offers") and let them opt in. A useful lead magnet, such as a checklist, price guide or seasonal reminder service, gives prospects a reason to subscribe before they are ready to buy.

Segment from the start, even simply: customers versus prospects, residential versus commercial, which service they bought. Sending a strata manager the same email as a homeowner wastes attention. Most email platforms let you tag contacts as they arrive, and the segments make everything you send more relevant.

What to send and how often

Three kinds of email do most of the work for a small business. The regular newsletter, monthly or fortnightly, keeps you in mind: one useful thing (a tip, a seasonal reminder, a short case study), one piece of news or proof, one offer or call to action. Transactional and lifecycle emails (booking confirmations, follow-ups after a job, review requests, reminders when a service is due) are sent automatically at the right moment and are often the highest-performing emails you have. Campaign emails announce something specific: a seasonal offer, a new service, an event.

Write like a person. A short, plain-text-feeling email from the owner with a clear subject line and one request outperforms a glossy template with six sections. Keep the subject honest and specific, put the point in the first two lines, and make the single action obvious. Send at a consistent rhythm so people come to expect it; test days and times rather than guessing.

Measure what matters

Open rates have become unreliable since privacy changes in mail apps began hiding them, so treat them as a rough signal only. The numbers that matter are clicks, replies, bookings and sales traced back to the email, along with unsubscribes and complaints, which tell you when you are sending too much or the wrong thing. Use tracked links to your booking or shop pages, and ask new customers how they heard about the offer. Review each send briefly and the overall program quarterly. If a type of email consistently produces nothing, change or drop it.

How to start email marketing lawfully and well

1. Choose a reputable email platform One that manages unsubscribes, consent records and segments for you.
2. Set up consent at every touchpoint Forms, quotes, invoices, counter, bookings; say what people will receive.
3. Import only contacts you can lawfully email Customers and people who opted in; record the basis for each.
4. Create two or three segments Customers versus prospects, by service or by customer type.
5. Set up lifecycle emails first Confirmation, post-job follow-up with review request, and service-due reminders.
6. Start a monthly newsletter One tip, one proof, one offer, written in the owner’s voice.
7. Track links to bookings and sales Know which emails produced revenue, not just opens.
8. Review and prune quarterly Drop what does not work; remove long-unengaged contacts to protect deliverability.

Real-world example

A Hobart wine shop turns its receipts into a list

Battery Point Cellars is an independent wine shop with a loyal local clientele and a small online store. The owner, Ren, has eleven hundred email addresses collected at the counter over several years, but has only ever sent two emails, both announcing sales. Before sending anything else, he checks what he can lawfully use: customers who bought from him have an existing business relationship, so he can infer consent for relevant messages, but he removes a few hundred addresses from an old tasting-event sign-up sheet whose consent he cannot evidence, and sets up a clear opt-in at the counter and online checkout going forward.

He segments the list into online buyers, in-store regulars and the people who attended tastings. Each month he sends a short email: one wine he is excited about and why, one short note about a producer, and one offer with a tracked link. Online buyers get a free delivery offer; locals get the tasting dates. Automated emails go out after each online order with a follow-up a fortnight later asking how they enjoyed it. Within six months the monthly email is reliably his best online sales day, the tasting evenings fill from the list alone, and his unsubscribe rate stays very low because the emails read like a note from someone who knows wine, not a catalogue.

Common mistakes

• Buying or scraping a list It breaches the Spam Act, damages your sender reputation and produces almost no sales. Build from people who know you.
• Only emailing when you want something A list that hears from you twice a year, both times a sale, learns to ignore you. Be useful between offers.
• Too much in one email Six sections and four buttons means no action. One useful thing, one proof, one request.
• Hiding the unsubscribe link It is legally required and making it hard only generates spam complaints, which hurt deliverability far more than an unsubscribe.
• Judging by open rates Opens are no longer reliable. Measure clicks, replies, bookings and sales.
• Skipping lifecycle emails The follow-up after a job and the service-due reminder are usually the highest-performing emails a small business can send, and they run themselves.

KPIs to track

• Revenue or bookings per send Tracked through links and codes. The number the program exists to produce.
• Click rate Clicks divided by delivered emails. Compare each send against your own average rather than industry figures.
• List growth from consented sign-ups New subscribers per month, net of unsubscribes.
• Unsubscribe and complaint rate Rising numbers mean too frequent or not relevant. Complaints in particular should stay very close to zero.
• Deliverability The share of emails reaching inboxes, reported by your platform. Prune unengaged contacts to protect it.

Frequently asked questions

Can I email past customers without them ticking a box?

Often yes. The Spam Act allows consent to be inferred from an existing business relationship where the message is relevant to it, and a customer who bought from you usually qualifies. Keep records, include identification and an unsubscribe link, and honour opt-outs within five business days. If in doubt, ask for express consent.

How often should I email?

Monthly is a safe starting rhythm for most small businesses, fortnightly if you have enough genuinely useful material. Consistency matters more than frequency. Watch unsubscribes as the signal that you are sending too much.

Does the Spam Act cover SMS too?

Yes. The same consent, identification and unsubscribe rules apply to commercial text messages, and ACMA has taken enforcement action against businesses over SMS marketing.

Should I use a template or plain text?

Simple wins. A clean, lightly formatted email that reads like a note from the owner usually outperforms heavy templates. Use images where they add something, such as a product or a finished job.

Key takeaways

• Email is usually the highest-return channel because you own the list and the people on it already know you.
• Consent, identification and a working unsubscribe are legal requirements under the Spam Act; record consent for every address.
• Build the list from customers and genuine prospects at every touchpoint; never buy one.
• Lifecycle emails first, then a consistent, useful newsletter, then campaigns to relevant segments.
• Measure clicks, bookings and sales, not opens; prune unengaged contacts to protect deliverability.
