Changing Email Security Requirements for 2024

Recent updates from Gmail and Yahoo signal a significant shift in how emails are handled, emphasizing the importance of these changes for all email users and senders. In this blog post, we will explore the upcoming changes, how they may impact your email communications and we also provide a tool to quickly check if your domain has everything in place.

Overview of New Requirements

To start off, let’s take a look at the new requirements that major email providers like Gmail and Yahoo are implementing. These changes aim to enhance security, authentication, and spam protection measures within their platforms. By adhering to these requirements, senders can ensure their emails are delivered successfully without being flagged as spam or phishing attempts.

  • Gmail: Starting in 2024, Gmail will require bulk email senders to authenticate their messages, facilitate easy email unsubscription, and maintain a spam complaint rate below 0.3%​​.
  • Yahoo: Similarly, Yahoo is enforcing standards like sender authentication and swift unsubscribe processes, underscoring the importance of responsible email practices​​.

According to a recent blog post by Postmark, Gmail and Yahoo will be implementing stricter policies regarding SPF (Sender Policy Framework) and DMARC (Domain-based Message Authentication, Reporting & Conformance) authentication protocols. This means that senders will need to properly configure these protocols for their domains to maintain optimal deliverability rates.

Key Changes and Their Implications

So what do these changes mean for you as an email sender? Firstly, it is crucial to ensure that your domain is properly set up with SPF and DMARC records. These records help verify the authenticity of your emails and prevent them from being marked as spam or rejected altogether.

This is a summary of the new key changes:

  • Authentication: SPF, DKIM, and DMARC will become essential for domain ownership verification and email authenticity​​. For­ DMAR­C you will­ need­ to set at mini­mum a p=no­ne poli­cy.
  • Ease of Unsubscribing: Providing a clear, one-click option for recipients to unsubscribe from emails is mandatory​​.
  • Spam Management: It’s crucial to keep spam complaints below the threshold of 0.3%, indicating responsible email sending practices​​.

These changes aim to curtail phishing attempts and ensure that only legitimate emails reach your inbox. For businesses and bulk email senders, adhering to these standards is now crucial to maintain their sender reputation and email deliverability.
