What we check

Three ways good emails get binned.

Spam trigger words, by category

Urgency and pressure, money hype, overpromising, manipulative phrasing and offer bait — the word patterns filters have been trained on for twenty years. Every hit is highlighted in your copy, weighted by how hard it trips filters.

Australian Spam Act 2003

The Spam Act requires consent, clear sender identification, and a functional unsubscribe in every commercial email. We check your copy for an unsubscribe line, business identifiers (name, ABN, phone, address, website) and fake “Re:” subject lines — the things ACMA actually enforces.

Formatting red flags

ALL CAPS, stacked exclamation marks, link-stuffing, shortened URLs and thin “two lines plus a link” emails all score badly before anyone reads a word. We flag each one with the fix.

The 60-second version

The Spam Act 2003, for people who send email.

Australia's spam law comes down to three rules. Get them right and cold outreach is a legitimate, compliant sales channel — get them wrong and ACMA can and does issue penalties.

Consent comes first

You need express consent (they asked for it) or inferred consent — an existing relationship, or a conspicuously published work address for B2B messages relevant to the person's role — before you send.

Say who you are

Every commercial email must clearly and accurately identify the business that authorised it. A signature with your business name, ABN and contact details covers it.

Unsubscribe must work

A functional, low-cost opt-out in every message, honoured within 5 business days and kept working for at least 30 days after sending. “Reply STOP” or an unsubscribe link both count.

General guidance only, not legal advice. For the full requirements see the Spam Act 2003 and ACMA's guidance for business.
