This isn't generally required by law (but please correct me if I'm wrong; it's been some time since I worked in the email industry.) Requiring this from large senders is going beyond what the law requires.
Not all messages are subject to the laws that do exist around bulk email. For example, under the US CAN-SPAM law, "transactional" messages like purchase or shipping confirmations are not required to have unsubscribe links (even though they may be sent in bulk).
Some classes of bulk email that normal people think of as marketing are also exempt from the law, such as email from political campaigns. There are also gray areas, like transactional messages having a certain amount of marketing content in them.
I also believe the laws pertaining to bulk email do not apply to individual messages sent by a human. A particular email might be lawful for a single person to send individually, even though it might be unlawful for a program to send the same email as part of a bulk campaign.
It's unfortunately and surprisingly difficult to make generalizations about email.
