Emails don't need CDNs. They don't need images. They can be sent directly from one computer to the other.

There isn't a large infrastructure set up for email because it's so damn efficient that a 1990s era computer can serve as an email server for thousands of people.

Every organization can host its own email programs: servers, clients, spam filters, etc. Most businesses and companies still host their own email.

Do you have a source for this? Most companies I know of offload mail hosting to gsuite or Microsoft.
