The POP/IMAP server-based email standard is over 30 years old – that makes it almost as old as the internet itself!
Imagine for a moment if we still stored and shared files on floppy disks or watched our favourite YouTube cat videos on VHS tapes? Of course, that would not be very practical given the technology we now have at our fingertips.
Likewise, it is impractical for businesses to continue using an outdated email technology when a superior system, designed for the needs of modern businesses is available to use.
