Google And Yahoo Updated Email Authentication Requirements For 2025
Security Boulevard, Thursday, November 6th, 2025
Google and Yahoo have introduced a brand new set of email authentication requirements for bulk message senders. The requirements impact those who send > 5000 emails per day. To follow the new requirements, bulk senders need to deploy SPF, DKIM, and DMARC, enable easy unsubscription, and focus on message relevance.
Google has been the pioneer in encouraging, exercising, and enforcing stringent privacy policies. These policies ensure end-to-end protection of email transactions and communication. Google's new email authentication policies aim to reduce email fraud and spam in 2024.
In their latest email guidelines, Google has enforced email authentication deployments starting in Feb 2024. Domain owners who send bulk messages to Gmail addresses would be required to authenticate their emails with DMARC.
