In February 2024, Gmail started requiring that bulk senders comply with the new regulations outlined in the blog article.

1. Authenticate their email: Bulk senders must authenticate their emails following well-established best practices to enhance email security.
2. Enable easy unsubscription: Large senders must allow Gmail recipients to unsubscribe from commercial emails with a single click and process unsubscription requests within two days.
3. Ensure they’re sending wanted email: Gmail will enforce a clear spam rate threshold for senders to prevent Gmail users from receiving unwanted messages.

These practices are aimed at improving email security and user experience. Gmail emphasizes the importance of collaboration within the email community to implement these changes effectively.

These changes signify a commitment to enhancing email security and user experience, benefiting users worldwide.
