Sending Bulk Emails Will Require DKIM, DMARC, and SPF Security Starting in 2024

Published 6. 12. 2023

With increasing demands for security and protection against unwanted emails, we find ourselves in a situation where we must adapt to new rules set by leading email service providers. Gmail and Yahoo are entering the year 2024 with new rules for mass emails, and Microsoft is very likely to join them soon.

What does this mean for you?

From 2024 onward, these three key elements will be essential for successful bulk email distribution:


  • DKIM (DomainKeys Identified Mail): This element ensures that the email was sent by an authorized party and was not altered during transmission.

  • DMARC (Domain-based Message Authentication, Reporting, and Conformance): DMARC provides a mechanism for verifying the email processor, increasing the security of email delivery.

  • SPF (Sender Policy Framework): SPF identifies authorized servers that have permission to send emails on behalf of your domain.


While these technologies were previously considered recommended settings, from 2024, they will be necessary for the proper functioning of bulk email distribution.

The change in rules for sending bulk emails will affect Gmail (details can be found on their official blog), Yahoo, and most likely Microsoft, so proper security is indeed unavoidable.
