# Set Up Domain (Both Streams)

> Provision both sending identities on a domain you own in one call: send.<rootDomain> (marketing) and notify.<rootDomain> (transactional). Isolates transactional reputation from marketing sends. Idempotent — safe to call again if DNS records already exist. Returns DNS records for both identities. Requires API key with domains:write.
