How Often Should You Update Your DNS Records?
While there is no one-size-fits-all answer, a good practice is to review and update your DNS records at least quarterly. However, any significant changes in your
email service provider (ESP), email infrastructure, or domain configuration should prompt an immediate review. Additionally, regular audits can help you identify and fix any misconfigurations or outdated records.
What are the Consequences of Not Updating DNS Records?
Failing to regularly update your DNS records can lead to a host of issues, including poor email deliverability, increased risk of your emails being marked as spam, and potential
security vulnerabilities. Outdated records might not align with your current email-sending practices, causing legitimate emails to be rejected or flagged by recipient mail servers.
How to Update DNS Records?
Updating DNS records typically involves accessing your domain registrar's control panel or your DNS hosting provider's dashboard. Here are the general steps:
Log in to your domain registrar or DNS hosting account.
Navigate to the DNS management section.
Locate the existing SPF, DKIM, and DMARC records.
Update the records with the new information provided by your ESP or IT team.
Save the changes and verify them using tools like DNS lookup or email authentication testing services.

Regularly updating your DNS records is an indispensable part of an effective email marketing strategy. By keeping your SPF, DKIM, and DMARC records current, you can significantly enhance your email deliverability, protect your brand reputation, and safeguard against security threats. Make it a routine to review and update these records to ensure that your email marketing efforts yield the best possible results.
