Claim Domain

Claim a domain that is already verified by another team.

Body Parameters

name (string, required) — The name of the domain you want to claim.
region (string) — The region where emails will be sent from. Possible values: 'us-east-1' | 'eu-west-1' | 'sa-east-1' | 'ap-northeast-1'

Choose a subdomain for the Return-Path address. Defaults to send (i.e., send.yourdomain.tld). Avoid setting values that could undermine credibility (e.g. testing), as they may be exposed to recipients.

Track the open rate of each email.

Track clicks within the body of each HTML email.

Configure a custom subdomain for click and open tracking. For example, setting "links" on domain example.com will produce a CNAME record for links.example.com. Avoid setting values that have a negative connotation (e.g. tracking).
