Google , Yahoo, and Microsoft announced an upcoming change to their policies to enhance security, privacy, and overall user experience.
These changes aim to create a safer online environment for users and reduce the risks associated with email communication.
As a result, it is crucial for you to ensure that your email practices align with these updated policies to avoid any disruptions in communication. To maintain a seamless and secure exchange of emails, we kindly request your cooperation in adhering to the following guidelines:
1. Email authentication
Ensure that your email server supports industry-standard authentication protocols such as SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting, and Conformance). This helps in verifying the authenticity of the sender and prevents email spoofing.
1.1 SPF (Sender Policy Framework)
What is SPF?
SPF is an email authentication protocol that allows the domain owner to specify which mail servers are authorized to send emails on behalf of their domain.
How to set up SPF:
To implement SPF for your domain:
Access your domain's DNS settings.
Add a TXT record containing your SPF information. For example:
Example:
v=spf1 include:_spf.google.com include:spf.protection.outlook.com -all
Customize the "include" values based on the email service providers you use.
1.2 DKIM (DomainKeys Identified Mail)
What is DKIM?
DKIM adds a digital signature to outgoing emails, allowing the recipient to verify that the email was genuinely sent by the domain owner and has not been altered during transit.
How to set up DKIM:
To implement DKIM for your domain:
Generate a DKIM key pair, usually provided by your email service provider.
Add the public key as a TXT record in your domain's DNS.
Example:
selector._domainkey.yourdomain.com IN TXT "v=DKIM1; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQC2Gv1u0Awuzx2pLkoHw84BYz0RL1D8lPKQxdJmy8QF3gIytkTcSkVLrLeQsWMx5bV8TVTIh6aBREwhHwV7PLUzB4JY0ULdnG0sW/W3UrcLCYQWqBA2vq8+jOuj6DUMcBoFwP5rtbCm0LiPy1f+yaq2KFEnq5XkFDnETUpTTekQIDAQAB"
Adjust the "selector" and "p" values accordingly.
1.3 DMARC (Domain-based Message Authentication, Reporting, and Conformance)
What is DMARC?
DMARC builds on SPF and DKIM to provide a policy framework for domain owners to specify how email receivers should handle messages that fail authentication.
How to set up DMARC:
To implement DMARC for your domain:
Create a TXT record in your DNS with the DMARC policy. For example:
_dmarc.yourdomain.com IN TXT "v=DMARC1; p=reject; rua=mailto:dmarc@example.com; ruf=mailto:dmarc@example.com; fo=1"
Customize the "p" value based on your desired policy (none, quarantine, or reject).
Best Practices:
To maintain strong email deliverability:
1. Regularly monitor DMARC reports and adjust policies accordingly.
2. Test your SPF, DKIM, and DMARC configurations using online tools.
3. Keep your DNS records up to date as your email infrastructure evolves.
If you encounter any challenges during the implementation process or have questions, please reach out to your Email Administrator/ Email Service Provider.
2. Enable Easy Unsubscription
Email recipients must be able to unsubscribe from unwanted emails without any hassle. It should just take one click.
3. Ensure you are sending a wanted email
Based on email sender guidelines from Google, you should maintain a spam rate of 0.1% or less to verify recipients of your email successfully receive your emails.
If your spam rate is consistently 0.3% or more, you may experience email performance issues, including delays, spam filtering, or bounces.
Troubleshooting
Problem: Emails are being marked as spam
Problem: Emails are being marked as spam
Likely Cause: SPF, DKIM, or DMARC records are missing or incorrectly configured, or your spam complaint rate is too high.
What to Check: Verify that your SPF, DKIM, and DMARC records are valid and active. Review your spam complaint rate and email engagement metrics.
Resolution: Correct any authentication issues, send emails only to recipients who expect them, and regularly clean your mailing lists to maintain a healthy sender reputation.
FAQs
Do I need all three authentication methods?
Do I need all three authentication methods?
Yes. Google, Yahoo, and Microsoft strongly recommend implementing SPF, DKIM, and DMARC together for the best protection and deliverability.
How often should I review my authentication settings?
How often should I review my authentication settings?
Review your settings whenever you change email providers, update infrastructure, or experience deliverability issues.
Conclusion:
Google, Yahoo, and Microsoft have strengthened their email sender requirements to improve security and reduce unwanted email. To maintain reliable email delivery, ensure your domain is authenticated with SPF, DKIM, and DMARC, provide a one-click unsubscribe option, and follow email-sending best practices.
