  title: Mailchimp Find Member, Mark VIP, and Tag
  summary: Search a member by email, flag them VIP, then apply a VIP tag.
  description: >-
    A find-then-act enrichment flow for high-value contacts. The workflow
    searches the audience for a member by email and branches: when a match is
    found it patches the member to set VIP status and then applies a VIP tag for
    segmentation, and when no match is found it ends. The matched subscriber
    hash threads from the search into both write steps. Authentication uses HTTP
    Basic auth with any username and your Mailchimp API key as the password.
