iCloud Mail

iCloud Mail is a cloud storage and synchronization service created by Apple Inc. Launched on October 12, 2011, it allows users to store and access data across multiple devices, including Apple Mail, Apple Calendar, Apple Photos, Apple Notes, contacts, settings, backups, and files. It is integrated into various operating systems, such as iOS, iPadOS, watchOS, tvOS, macOS, a limited web interface, and Windows applications.

The service offers a free storage plan of 5 GB, which can be upgraded to 50 GB, 200 GB, or 2 TB through paid plans. All paid plans feature iCloud+ that adds Private Relay, Hide My Email, and Custom Email Domain functionality. As of 2018, iCloud Mail had an estimated user base of 850 million, up from 782 million in 2016.

In December 2022, Apple implemented optional end-to-end encryption for all iCloud data, except for Calendar, Contacts, and Mail, which rely on legacy sync technologies to ensure compatibility with third-party apps (CalDav, CardDav, IMAP). The feature was first launched to US customers on December 13, 2022, and released worldwide on January 23, 2023.

Some key features of iCloud Mail include its seamless integration with the Apple ecosystem, allowing for easy collaboration with other users, and the availability of customer support from Apple. However, iCloud Mail has been designed by Apple to primarily offer personal email solutions, resulting in a lack of advanced features available in competing email providers.
