    from: 'Accounts <accounts@yourdomain.com.au>',
    to: order.email,
    subject: 'Tax Invoice & Receipt (AUD)',
    html: `<p>Thank you for your payment of ${order.total} AUD (includes 10% GST).</p>`,

Frequently Asked Questions

Everything you need to know about transactional email API Australia

Clear, transparent answers on deliverability, API authentication, and rate limits.

Our servers are in the EU, so an Australian API call is a long round trip — which is why the send is accepted and queued on the call rather than held open while a provider is contacted. Your signup and checkout flows. SadaSend processes calls in Sydney under 20ms.
