James Moody co-founded Sendle in Sydney in 2014 with Sean Geoghegan and Craig Davis. The company offered small businesses door pickup, flat prices and, from 2015, carbon neutral delivery.
In 2015 Australia Post opposed the slogan 'Post without the office'. IP Australia ruled for Sendle in 2017, the year it also signed a deal with DHL eCommerce for international sending. Sendle won a Telstra Business Award in New South Wales in 2016.
The company entered the United States in 2019 and Canada in 2022. It raised A$5 million in 2016, A$20 million in 2019, A$19 million in 2020, A$45 million in 2021 and A$16 million in 2024.
In August 2025 Sendle announced a merger with ACI Logistix and FastMile to form FAST Group. Sendle stopped taking bookings on 11 January 2026 and entered creditors' voluntary liquidation on 25 February 2026. McKenna Worldwide bought the brand in July 2026 and the website returned in October.
