JMAP
A modern email synchronization protocol principally designed by Fastmail and standardized as IETF RFC 8620 in 2019. Based on JSON, it reduces round-trip requests compared to traditional IMAP and performs more efficiently on mobile networks.
Timeline (last 90 days)
JMAP processes multiple operations in bulk through a single HTTP request, reducing the number of network round trips, and natively supports push notifications.
Fastmail is the provider with the most complete JMAP support among commercial email services, and third-party email clients such as Mimestream have also begun supporting the JMAP protocol.
