There are two types of domains used by Bloomreach Engagement that can be customized:

  • CDN domain for
    • single-tenant instances
    • multi-tenant instances (BETA)


CDN domain for multi-tenant instances is currently unavailable.

Custom CDN domain

The default CDN domain is It has several functions, namely:

  • Consent page
  • Surveys
  • Email click tracking - all email links go through the CDN link and then redirect to the target URL
  • Email open tracking pixel

In order to set up the custom CDN domain, DNS records need to be added on both Bloomreach Engagement and the client's side.



Only the Super Admin role or a combination of both Account Admin with the Instance Manager role can change the field Custom Public URL.

Once the DNS records are set up, the domain needs to be set up in the respective project(s) where you expect the domain to be used. This should be performed in Project Settings by filling in the field "Custom Public URL" as shown below. Do not forget to save the settings.



Custom CDN domain is available for clients with single-tenant or exclusive instances. There are security and performance advantages for private and exclusive instances.

Custom CDN Domain is also available for multi-tenant instances but for now, only in the Beta version.
