We will need to ask for sendgrid api-key upfront (provide some docs for people to register it)
(should have: allow optional opt-in, if API key is not-null)
(nice to have: for people to add it later via make command)

Domain validation

• call API and figure out the route53 needed for domain validation
• Either from init step (call API and figure out the route53 needed for domain validation)
• or from Make apply step's beginning to fill in the route53 validation records
• call domain verification (can we do this via patch)
