Gmail to require email authentication and easy unsubscribes to reduce spam in 2024

Starting February 2024, bulk email senders to Gmail must authenticate emails and allow one-click unsubscribes.
Google aims to set new industry standards to improve email hygiene and security.
Bulk senders must stay under a 0.3% spam rate threshold to reach Gmail inboxes.
Google already blocks 99.9% of spam with AI defenses.
The changes intend to give users more control over unwanted emails and prevent spoofing.
