Issue Description
Changing your primary domain can be a bit of a daunting task if you don't know where to start, this guide will walk you through the steps you will need to take to use a new domain with your Marketo instance.
Issue Resolution
- Create your new Landing Page CNAME and point that to your Marketo instance. If this new CNAME is going to be used as your primary domain, then the original Domain Name in Admin > Landing Pages will need to be changed to reflect your new domain. The original domain should be added as a domain alias so any URLs referencing the original domain will continue to work.
- Adding a new primary branding domain (CNAME) for emails is also recommended when changing domains. This will allow tracked links in emails to reference the new domain going forward. You'll want to leave the original branding domain (CNAME) active and listed so that tracked links in any previsouly sent emails will continue to work.
- If you plan on signing your emails with your new domain, setting up a new SPF/DKIM record is recommended to help keep your deliverability rates as high as possible.
