Best Email Marketing Tools for Australian Businesses in 2026

Australian email marketing is governed by the Spam Act 2003, which requires explicit consent from recipients, a functional unsubscribe mechanism, and sender identification in every commercial email. Most major email platforms are compliant with these requirements but there are differences worth knowing about for Australian businesses.

Mailchimp for Australian businesses

Mailchimp is compliant with the Australian Spam Act and includes unsubscribe functionality by default. The main considerations for Australian businesses are the pricing in USD (which fluctuates with the exchange rate) and data storage. Mailchimp stores data in the United States. For businesses with data sovereignty concerns, this may be relevant. Mailchimp free covers 500 subscribers which is sufficient for small businesses starting out.

Campaign Monitor: best for Australian businesses

Campaign Monitor is an Australian company founded in Sydney, now operating globally. Data can be stored in Australian data centres, which addresses data sovereignty requirements for businesses that need this. The platform is fully compliant with the Spam Act. At comparable pricing to international alternatives, Campaign Monitor is worth considering for Australian businesses that prefer local data handling and local support.
