If the email addresses are published on the website then that would be fine but I wouldn't like to say what the ruling is with whois emails
Mr Bacon Farmer,
Thankyou for lodging a report with the ACMA.
In order for us to look into this problem further could you please clarify if
you have had any previous association with these companies and if you have
tried to unsubscribe to the emails.
The ACMA can contact the business on your behalf and inform it of its
obligations under the Spam Act 2003. However, as you did not agree to the
disclosure of your electronic address the ACMA will be unable to have your
details removed from the mailing list.
If you would like the ACMA to request that you be unsubscribed from, please
reply to this email providing your consent for the ACMA to disclose your
electronic address.
If you have any queries about this matter, please contact me by return email.
Yours sincerely
Anti-Spam Team
Australian Communications & Media Authority
Just because a site lists an email address does not make it acceptable to send unsolicited email. I'd suggest to the OP, read the ACMA guidelines as it will ultimately govern what is an isn't SPAM in Australia.
Really? I'm no expert but I would have thought that a company listing their email address was inviting contact?
It's a little bit of a gray area. Inferred consent is not automatic for a publicly available address. This link summarises how it works: http://www.acma.gov.au/WEB/STANDARD/pc=PC_310515
If your business sells washers for taps, you cannot send commercial emails to all businesses with conspicuously published email addresses on the
assumption that they all need washers in their taps. However, you could send your promotional emails to plumbing supplies stores.
With conspicuous publication, there must be a strong link between what you are promoting and the recipient's role or line of business.
