Mailjet - SPF & DKIM Configuration

1. Log in to your Mailjet account and navigate to Account Settings.
2. Go to the "Sender domains & addresses" section.

3. Click the gear icon next to the domain you want to authenticate and select "Setup SPF/DKIM Authentication."

Once clicked, you'll be provided with your SPF and DKIM records.

Mailjet – SPF Record Configuration

Important Note: Mailjet provides the SPF record v=spf1 include:spf.mailjet.com ?all, however you should not publish this in your DNS or add include:spf.mailjet.com to your existing SPF record. Mailjet emails will still fail SPF checks even if you do. The correct setup requires a CNAME record instead. To pass the SPF check:

• Step 1: Go to your domain's DNS zone.
• Step 2: Create a subdomain using the prefix "bnc3" - e.g., bnc3.yourdomain.com.
• Step 3: Add a CNAME record with bnc3.yourdomain.com as the Name/Host and bnc3.mailjet.com as the Target/Value.
  
• Step 4: Once the record is published, contact Mailjet's support team and ask them to activate your personalized return path. After activation, SPF alignment will pass correctly using the bnc3.yourdomain.com subdomain.
  
  
  

  Mailjet – DKIM Record Configuration

  
  To set up DKIM, copy the provided DKIM record and publish it as a TXT record in your domain's DNS zone.

After saving, return to Mailjet and click Refresh.

If everything is configured correctly, a green checkmark will confirm that your DKIM record has been successfully verified. As for SPF, do not worry about it showing a warning - you only need to publish the CNAME record mentioned above and ask Mailjet's support team to activate it, and that's it.
