## Solution

Perform the following steps:

1. Get the domain you want to add as a custom domain.
2. Ensure the domain has the correct Canonical Name (CNAME) values configured.
3. Add a CNAME record in your Domain Name System (DNS) settings, pointing to the MoEngage domain.
4. Use the appropriate CNAME value based on the cluster you are on.

## Example

For instance, CNAME value: ux.mnge.co (X stands for the cluster).

<Info>
  To find the name values of a custom domain, you can use methods such as nslookup or free online tools such as [CNAME LOOKUP - MxToolbox](https://mxtoolbox.com/CNAMELookup.aspx) and [DNS Lookup](https://www.nslookup.io/).
