The Australian Communications and Media Authority (ACMA) has enforcement responsibility for the Spam Act. However, there is more to this law than just not sending without consent.
The three main things to remember are:
- Consent - make sure you have consent to contact the recipient and can prove you have obtained it.
- Identify - include accurate information to identify yourself or your organisation as the authorised sender of the message
- Unsubscribe - make sure your messages have a functional unsubscribe facility, so that recipients can unsubscribe (also known as "Opt Out") at any time.
Some organisations are exempt, such as charities, educational institutions and the government of course!
