Every link you include in your Marketo emails will have a tracking code automatically appended when sent. For those in highly regulated industries, your company may require that you securely encrypt the Marketo tracking links. Remember that Marketo takes the URLs you place inside of emails and shortens them using the "Branded Tracking Link" domain (this is another CNAME you set up in Marketo under Admin--> Email). These tracking links are how Marketo enables you to track engagement with your emails.

Do I NEED Secured Domains for Tracking Links?
Secured Domains for Tracking Links ensures that tracking links can be served securely for domains which have implemented HSTS (HTTP Strict Transport Security). HSTS is a web server directive which more and more companies are choosing to enforce that tells the browser all subsequent requests for resources on that domain to be loaded through HTTPS. Securing your tracking links has additional benefits some companies find valuable:
- HTTPS is displayed instead of HTTP when hovering over the link within the email (for those provisioned post- Apr 15, 2019 - please open a support case if you're unsure or want HTTPS display enabled)
- It prevents the browser from temporarily displaying a "Not Secure" warning instead of the Lock icon (to the left of the address bar) while redirecting to your landing page
- Secured links may help improve deliverability, as that is a ranking factor in their algorithms.
If you have HSTS implemented on your top-level domains or sub-domains, you WILL NEED Secured Domains for Tracking Links.
Additional information on HSTS and how to check if your company has it implemented can be found here: SSL: The HSTS policy and your Marketo subdomains
