Sinch launches Australian hosting region for Mailgun

Sinch has launched an Australian hosting region for Sinch Mailgun, allowing customers to keep email data stored in Australia.

The new region initially supports Mailgun Send, the group's email API product, on local infrastructure. Transactional email data and logs will remain onshore, including email sending data, delivery events, analytics and backups.

The launch is aimed at sectors with tighter obligations around where data is held and how it is protected, including financial services, healthcare and higher education, where routine customer and patient communications can involve sensitive information.

For banks and other financial organisations, the local setup can support transactional emails such as payment reminders, card lock or unlock notifications and one-time passwords. Healthcare providers can keep appointment reminder data in Australia, while universities and colleges can do the same for enrolment confirmations and other student communications.

Australian businesses have faced mounting pressure to manage customer data more carefully as policymakers review privacy rules and regulators sharpen their focus on information security. Sinch pointed to reforms to the Privacy Act, Australian Privacy Principle 8 and APRA's CPS 234 standard as factors driving demand for local hosting.

The Australian region carries SOC 2 and ISO 27001 certifications. It is designed for organisations that need local data residency without relying on hosting in the United States or Europe.

Regional demand

Although the hosting region is aimed at Australian organisations, it is also available to customers in New Zealand and elsewhere in Asia Pacific. Those businesses may want email delivery and hosting closer to their users than options based in the US or EU.

Data residency has become a more prominent issue for software and communications providers serving regulated industries. Customers increasingly want assurance that operational data generated by routine digital interactions stays within national borders, especially when vendors process logs, backups and performance records alongside message content.

That shift has prompted global providers to add local infrastructure in markets where public policy and customer procurement standards place greater weight on sovereign control of information. Email systems have drawn particular attention because they often handle authentication messages, account notices and health or education updates that can reveal personal details even when the message itself appears routine.

Sinch has also been expanding its position in Australia. It recently rebranded MessageMedia as Sinch Engage and announced an artificial intelligence partnership with Australian company Coderra, adding to its messaging and communications portfolio in the market.

Sinch said those moves mean Australian customers can use email, WhatsApp, SMS and AI-based messaging tools through one supplier with a local presence. The latest infrastructure launch adds email data residency to that offering.

Sinch reported net sales of USD $3 billion in 2025 and said it serves more than 200,000 customers globally. The Stockholm-headquartered company handles more than 1 trillion customer interactions each year across messaging, email and voice services.

"Australian enterprises want a trusted partner who can keep their most critical customer data within Australia without sacrificing speed. Sinch Mailgun delivers that," said Wendy Johnstone, Executive Vice President, APAC at Sinch.

"We are enabling organisations with Australia data residency requirements to seamlessly route high-volume, secure communications over fully certified, onshore infrastructure," said Johnstone.
