  title: Hunter Verify and Add to Campaign
  summary: Verify an email, add it to a campaign when valid, then start the campaign.
  description: >-
    Protects an outreach sequence from bad addresses by verifying an email
    before it is ever added to a campaign. The flow branches on the
    verification status: a valid address is added as a campaign recipient and
    the campaign is started, while any other status ends the flow. Each step
    spells out its request inline, including the api_key query parameter, so the
    flow can be read and executed without opening the underlying OpenAPI
    description.
