  title: Mailchimp Pre-Send Checklist then Send Campaign
  summary: Run the send checklist for a campaign and only send if it is ready.
  description: >-
    A guarded send. The workflow pulls the campaign's send checklist and
    branches on the is_ready flag: when the campaign passes all checks it
    triggers the send action, and when it does not it ends without sending so a
    half-configured campaign is never delivered. This is the safe wrapper around
    the otherwise irreversible send call. Authentication uses HTTP Basic auth
    with any username and your Mailchimp API key as the password.
