6. Apple Business Mail — New Entrant for Apple Ecosystem
Launching April 14, 2026, Apple Business Mail offers free business email for up to unlimited users through iCloud. Tight integration with Apple devices and a focus on privacy make it appealing, but it is limited to the Apple ecosystem and lacks advanced admin controls.
