Custom domains

This page covers how to use custom domains to portray a consistent brand image.

Domain requirements

• Domains must be procured, owned, and managed by you.
• The domain used for this feature must be unique (that is, different from your website domain), and the domain can’t be used to host any web content.
  • You can also use unique subdomains, such as sms.braze.com or whatsapp.braze.com.

Delegating your custom domain

When you delegate your domain to Braze, we automatically handle the certificate renewal to prevent a lapse in service.

To delegate your domain to Braze, do the following:

1. Bring a domain that meets the above requirements to your customer success manager. Braze will then check the existing DNS configuration for the domain and confirm that:

• No CAA records exist OR
• CAA records do exist but have a record for <any number> issue "letsencrypt.org" or <anynumber> issuewild "letsencrypt.org"

2. Create four new A records, one for each IP, and confirm that they are the only A records that exist for the domain link host:
   • 151.101.130.133
   • 151.101.194.133
   • 151.101.2.133
   • 151.101.66.133

Using custom domains

After they’re configured, custom domains can be assigned to one or multiple WhatsApp and SMS subscription groups.

Campaigns sent with click tracking turned on or built within WhatsApp template messages will use the assigned domain associated with your subscription groups.

Frequently asked questions

Can delegated domains be shared across multiple subscription groups?

Yes. A single domain can be used with multiple subscription groups. To do so, select the domain for each subscription group that it should be associated with.

Can delegated domains be shared across multiple workspaces?

Yes. Domains can be associated with subscription groups in multiple workspaces, assuming the workspaces are contained within the same company.
