Introduction
SendGrid, the tool we use to send out mailings from within our application, has recently updated its policy. As part of this update, it is now required for our customers to set up DMARC (Domain-based Message Authentication, Reporting, and Conformance) on their DNS (Domain Name System).
What is DMARC?
DMARC is an email authentication protocol that helps protect email senders and recipients from email fraud. By implementing DMARC, you can enhance the security of your email communications and ensure that your recipients can trust the emails they receive from your domain.
Why is DMARC Required for SendGrid?
SendGrid has implemented this requirement to enhance the deliverability and security of email communications. By setting up DMARC, you not only comply with SendGrid's policy but also contribute to a more secure and trustworthy email ecosystem.
How to Set Up DMARC for Your Domain
Setting up DMARC involves making changes to your DNS records. Here is a step-by-step guide to help you through the process:
Access Your DNS Provider: Log in to your DNS provider's platform. This is where you manage your domain's DNS records.
Create a DMARC Record: Add a DMARC TXT record to your DNS. The record should include information about how you want DMARC to handle emails that fail authentication. Below is an example of a DMARC record:
cssCopy codev=DMARC1; p=quarantine; rua=mailto:[email protected]; ruf=mailto:[email protected]
v=DMARC1: Indicates the DMARC version.p=quarantine: Specifies the policy for messages that fail DMARC authentication. In this example, such messages will be quarantined.
You can customize the record based on your preferences. Be sure to replace
[email protected]with the email address where you want to receive DMARC reports.Publish the Record: Save the changes and publish the DMARC record to your DNS.
Monitor DMARC Reports: Regularly review the DMARC reports to gain insights into your email authentication status. Make adjustments to your DMARC policy as needed.
