Yes! You can customize tracking links to make your email URLs look more professional and brand-aligned. This not only improves your brand perception but can also boost deliverability.

Default Tracking Link Format

By default, Mailjet tracking links use the following structure:

https://os8n.mjt.lu/redirect/12345/hostname/link

After customization, the link will look like this:

https://subdomain.yourdomain.com/redirect/12345/yourdomain.com/link

Why Customize Tracking Links?

✅ Improved Deliverability

• Spam Filters: Custom tracking links aligned with your domain build trust with spam filters, reducing the risk of emails being flagged as spam.

• Domain Reputation: Using your own domain helps maintain a strong sender reputation and supports long-term deliverability.

✅ Brand Consistency

• Professional Appearance: Links featuring your domain appear more legitimate to recipients.

• Brand Recognition: Consistent branding across emails reinforces trust and familiarity.

✅ Enhanced Security

• Phishing Prevention: Recipients are less likely to distrust or block links coming from your verified domain. This makes it harder for attackers to spoof your brand.

✅ SEO & Link Trustworthiness

• Search Engine Trust: Custom links appear more credible to search engines and security tools.

• Reduced Blocking: Branded links are less likely to be flagged or blocked.

How to Customize Your Tracking Links

Before proceeding, make sure your sender domain is verified with Mailjet. If it hasn’t been verified yet, visit your Sender Addresses page to complete the process.

1. Go to Account Settings

   Navigate to Account settings → API Key management (Primary and Subaccount)
   

2. Edit API Key

   Click the cogwheel next to the API key and select Edit API Key.
   

3. Create a CNAME Record

   To customize your tracking hostname, start by creating a CNAME record. In your domain host account, add a CNAME that points to Mailjet:

   • Type: CNAME

   • Host/Subdomain: Choose a short name (e.g., go, links, redir)

   • Value: t.mailjet.com.

     Tip: Short subdomains keep links clean (e.g., go.yourdomain.com).

     After you have created your CNAME record, enter your subdomain name and select the domain as shown on the screen below. Then click ‘Update’ to continue.

     Example (BlueHost):
     

4. Updating Image URLs (Optional)

   If you want to update URLs for previously uploaded images in your templates:

   • Check the Update URLs box before confirming the changes.

   • Note: This does not affect existing campaign URLs.

   • The update process may take some time; please do not leave the page until it is complete.

Troubleshooting

If you see an error like “Entry is missing”, it usually means:

• The CNAME record is incorrect, or

• DNS propagation is still in progress (may take a few hours).

Double-check your settings, and if the issue persists, contact our Support Team.

Cloudflare Proxy Configuration

If you manage your DNS with Cloudflare, you need to turn off Cloudflare's proxy for your CNAME record and set it to DNS only. This is required because we use the CNAME record to generate and renew the certificate, as well as to terminate TLS whenever an HTTPS link is clicked.

Setting Up CAA Records

If you've published a Certification Authority Authorization (CAA) record for your domain, ensure it includes issue: letsencrypt.org to allow Mailjet to generate an SSL certificate for your subdomain.

• Root Domain Level CAA Record: The CAA record should be set at the root domain level (e.g., yourdomain.com) to cover all subdomains.
• Specific Subdomains: If you’re using a specific subdomain (e.g., subdomain1.yourdomain.com) for HTTPS tracking, place the CAA record at the higher level (yourdomain.com) since placing it directly on the subdomain with an existing CNAME may not be allowed.

Examples

• Using a Subdomain for HTTPS Tracking: If you want to use subdomain1.yourdomain.com as your custom HTTPS tracking host, point the CNAME record to t.mailjet.com. Set the CAA record at yourdomain.com.
• Using a Fourth-Level Domain: If you’re working with a domain like subdomain2.subdomain1.yourdomain.com, set the CAA record at subdomain1.yourdomain.com or yourdomain.com. The CAA checks are recursive and start from the subdomain, moving up to the root.

✅ Congratulations!

You’ve successfully customized your tracking hostname—improving deliverability, security, and brand consistency for your emails.
