New set of requirements for Senders by Google and Yahoo

Last update: August 28, 2025

Gmail and Yahoo Mail have recently introduced a new set of requirements for senders by Google and Yahoo. These rules, effective from February 2024, aim to protect user inboxes and improve email deliverability.

First, you must set up DKIM, SPF, and DMARC records for your sender domain. This step replaces simple email address verification and ensures your domain proves its authenticity. As a result, your emails are less likely to land in spam. You can follow this guide to configure DKIM, SPF, and DMARC for detailed instructions.

The second one is the introduction of easy one-click unsubscribe button on the email header. MailBluster has also implemented an easy one-click unsubscribe header automatically to all outgoing emails to make it easier for recipients to unsubscribe, reducing the spam complaints, as shown below :

The third one is Mailbox providers will require that all senders keep spam complaint rates below 0.3% to avoid having their email treated as spam by the mailbox provider. It is recommended to enroll with Google Postmaster Tools to monitor their spam complaint rates for Gmail recipients.

Kindly be informed that disregarding these requirements could result in Gmail and Yahoo rejecting the delivery of emails to their intended recipients. By following this new set of requirements for senders by Google and Yahoo, you can achieve higher inbox placement rates, maintain compliance with email regulations like CAN-SPAM and GDPR, and reduce negative engagement metrics. Always keep your domain records up-to-date and monitor campaigns to ensure compliance.
