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

  • CDN domain for

    • single-tenant instances

    • multi-tenant instances (BETA)

  • [Custom tracking domain](🔗)

### 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.**

Contact your CSM or Sales for more information.

### Custom Tracking Domain

By default, Bloomreach Engagement uses the domain to serve JS SDK, service worker for web push notifications, and all of our API endpoints. However, you can configure a Custom Tracking Domain, find out more [here](🔗).
