Confirm SPF, DKIM, DMARC and MX records


Last updated on Jul 18, 2023

Mystrika requires your email address to be completely functional (send and receive) to ensure it doesn't disturb your neighbor in the Warmup Pool.

In short, warmup emails to and from your email address should not be bouncing and creating discomfort to other members of the Warmup Pool.

This requires your SPF, DKIM, DMARC and MX records to be properly set.

Let's take a look at each one of them :

MX Records: MX records play a vital role in directing emails to your inbox. Without them, emails send to your email address may never reach them, resulting in a bounce email to email sender.

We highly advise not to have more than only ESP (Email Service Providers) record on your domain.

Ensure proper MX record configuration to guarantee seamless email delivery.

SPF Record: An SPF record serves as a security measure by specifying authorized domains allowed to send emails on your behalf.

It helps prevent unauthorized sources from sending emails using your domain, safeguarding your reputation and email deliverability.

DKIM Record: By adding a DKIM record to your domain, emails are digitally signed, making them easily traceable and verifying their authenticity.

This ensures that recipients can trust the source of the email and helps protect against email spoofing.

DMARC Record: DMARC (Domain-based Message Authentication, Reporting, and Conformance) provides an additional layer of email authentication.

It combines SPF and DKIM checks and allows domain owners to set policies for handling emails that fail authentication, helping to prevent email fraud and ensure legitimate email sources.

While MX records are for receiving of your Emails sent to your email address, SPF, DKIM and DMARC are for sending validation. And in today's era they are mandatory.

To further add, Mystrika requires your DMARC to set on "quarantine" or "reject" mode, instead of "none", as "none" provides Zero security for DMARC.

Just changing value "p=none" to "p=quarantine" or "p=reject" changes the mode for DMARC action.

Wondering if DNS records affect email deliverability?

The answer is a resounding yes!

An MX record is essential for receiving replies and ensuring smooth communication.

But that's not all. The other three records—SPF, DKIM, and DMARC—also play a crucial role in optimizing your account's performance.

To ensure your records are set up correctly, you can utilize third-party tools like Easydmarc.com, MXToolbox, or DMARCian. Simply enter your domain, and these tools will provide valuable insights into the status of your records.

By testing and confirming proper DNS record configuration, you can maximize email deliverability, enhance your account's performance, and ensure seamless communication with your recipients.
