This article explains the 2024 email authentication changes by Google and Yahoo, detailing new DKIM and DMARC requirements, the ban on @gmail.com sender emails, and stricter spam complaint limits with actionable steps.
Significant transformations are taking place in email communication as Google and Yahoo roll out new authentication and spam-prevention protocols starting in February 2024. These updates aim to improve email security, enhance deliverability, and establish trust between senders and recipients.
Note: If you already have DKIM and DMARC set up, these changes will not impact you.
Understanding the Shift: Google's New Authentication Standards
What was once considered a best practice for bulk email senders has now become a mandatory requirement for ensuring email delivery. Both Google and Yahoo have implemented new authentication standards to:
-
Strengthen email security and reduce phishing attempts
-
Improve deliverability and sender credibility
-
Reduce spam and prevent unauthorized email spoofing
-
Protect domain reputation and ensure seamless communication
These changes will primarily affect high-volume senders but will also apply to all email senders to some extent.
Key Updates You Should Know
1. Mandatory Email Authentication
-
DKIM & DMARC Implementation: All email senders must have DomainKeys Identified Mail (DKIM) and a Domain-based Message Authentication, Reporting & Conformance (DMARC) record in place to ensure email authenticity and reduce spoofing risks.
-
Impact on Bulk Senders: Bulk senders who fail to authenticate emails may experience increased rejections, reduced deliverability, or complete blocking of their messages.
-
Action Required: If you haven’t already set up DKIM and DMARC, now is the time to do so.
2. Transition from @gmail.com to Custom Domains
-
Google encourages senders to use their own domains instead of generic @gmail.com addresses.
-
If you don’t currently have a custom domain, you can purchase and authenticate one through your email service provider to comply with the new requirements.
3. Keep Spam Complaint Rates Below 0.1%
-
Google is reinforcing a strict spam complaint threshold for email senders.
-
If your spam complaints exceed 0.1%, you may experience deliverability issues or permanent blocks.
-
To stay compliant, send only relevant, high-quality emails and allow recipients an easy way to unsubscribe.

Frequently Asked Questions (FAQs)
Who Will Be Affected by These Changes?
These new requirements apply to all email senders, with a more significant impact on bulk email senders. However, 1:1 emails and sales automation emails sent through The CRM's platform will not be affected.
What Happens If You Don’t Comply?
Non-compliance can result in:
-
Emails being rejected or marked as spam
-
Damage to your sender reputation
-
Long-term deliverability issues affecting email marketing success
Is There a Minimum Email Volume for These Rules to Apply?
No. Although Google has referred to 5,000 daily emails as an indicator of bulk sending, both Google and Yahoo have clarified that there is no safe threshold. Even low-volume senders should ensure compliance.
Can I Set Up Authentication Before the CRM Releases Its Native Tools?
Yes. You don’t need to wait—authentication can be set up manually. The CRM is enhancing tools to simplify the process, but early compliance is recommended.
What Is DKIM and Why Is It Important?
DKIM is an email authentication method that digitally signs emails, ensuring their integrity and verifying the sender’s authenticity. It helps prevent fraud and improves deliverability.
How Does DKIM Work?
-
When an email is sent, DKIM adds a digital signature using a private key.
-
The recipient’s email server verifies the email using a public key published in the sender’s DNS.
-
If the verification is successful, the email is considered legitimate and is delivered accordingly.
What Is DMARC and Why Is It Necessary?
DMARC is a security standard that helps email providers identify whether an email is legitimate or fraudulent based on DKIM and SPF verification.
How Does DMARC Work?
-
It instructs email providers on how to handle unverified emails—whether to allow, quarantine, or reject them.
-
It provides reports on unauthorized email activities to help domain owners prevent email spoofing and phishing attacks.
Are There Risks for Low-Volume Senders Using DKIM?
No. Some believe that low-volume senders may struggle to build a domain reputation, but data from The CRM shows that DKIM positively impacts open rates for senders of all sizes.
Will High-Volume Senders Face Deliverability Issues When Switching Domains?
Large senders may face initial disruptions when transitioning to their own authentication, but not adopting these measures could lead to complete email blocking.
If transitioning to a new domain, follow best practices, including warming up the domain by gradually increasing sending volume.
Google and Yahoo’s 2024 authentication updates are reshaping email communication by prioritizing security, trust, and deliverability. To ensure compliance and protect your email reputation, set up DKIM, implement DMARC, reduce spam complaints, and transition to a custom domain. The CRM remains committed to guiding users through these changes and ensuring a smooth adaptation to these new industry standards.
