Step 3: Click on Manage on the right side of your domain

Now, Mailjet will provide you with two DNS records unique to your domain.

Step 4: Ignore the SPF record for the reasons mentioned above and copy the DKIM record.

Step 5: Go to your DNS zone (In our case it’s in Cloudflare)

Note: Turn off any proxy settings if you’re using Cloudflare.

Once verified, you’ll be able to see Mailjet displaying Your DomainKey record looks good!

You can start sending emails and you’ll see them under the DMARC compliant tab with DKIM passing and aligning with your domain.

Note: Wait at least 24 hours to receive the updated reports

Setup SPF

As for the SPF configuration, you’ll need to:

Step 1: Head to your domain DNS zone.

Step 2: Create a subdomain for your main domain using the prefix “bnc3”.

Step 3: Add a CNAME record as the Name/Host and as the Target/Value.

Step 4: Add Mailjet’s include mechanism to your root domain’s SPF Record

Note: If you already have an SPF Record on your root domain, ensure that you simply add “” to your existing SPF Record. Creating an additional SPF Record for your root domain will cause duplication.

Step 5: Get in touch with the Mailjet support team and ask them to activate your personalized return path.
