versioning:
  scheme: none
  current: null
  docs: https://products.zetaglobal.com/sailthru/Content/developers/api-basics/technical.html
  note: >-
    The API carries no version identifier in its path, headers or parameters.
    The only versioned surface is the client-side JavaScript tag
    (spm.v1.min.js), where "v1" is a major-line marker rather than a release.
deprecation:
  policy_url: null
  sunset_header: false
  deprecation_header: false
  note: >-
    No deprecation policy, no RFC 8594 Sunset/Deprecation header support and
    no documented notice period were found. Product changes are announced in
    the release notes only.
sla:
  url: null
  uptime_target: null
  note: >-
    No public SLA or uptime commitment. Zeta Global's trust center lists a
    "Status Monitoring" control, but the underlying documentation is gated
    behind a SafeBase access request.
status_page:
  url: null
  state: inactive
  note: >-
    Sailthru's Atlassian Statuspage still exists but has been DEACTIVATED —
    https://sailthru.statuspage.io/ redirects to /inactive and renders "This
    page is currently inactive and can only be viewed by team members", and the
    branded https://status.sailthru.com/ returns HTTP 403. There is no
    replacement status page under zetaglobal.com (status.zetaglobal.com does
    not resolve). No StatusPage pointer is wired in apis.yml because there is
    no status page a customer or an agent can read.
  evidence:
  - {url: 'https://sailthru.statuspage.io/', status: 200, result: redirects to /inactive}
  - {url: 'https://status.sailthru.com/', status: 403}
  - {url: 'https://status.zetaglobal.com/', status: 0, result: does not resolve}

  current_owner: Zeta Global Holdings Corp.
  acquired: '2025-11'
  history:
  - {year: 2008, event: Founded in New York}
  - {year: 2018, event: Acquired by CM Group (later renamed Marigold)}
  - {year: 2025, event: 'Zeta Global completes acquisition of Marigold''s enterprise software business, including Sailthru'}
  - {date: '2026-01-14', event: 'Phased rebrand begins — Marigold name and logo replaced with Zeta across the Sailthru product'}
  note: >-
    The developer surface moved with the company. sailthru.com now 302s to
    zetaglobal.com/sailthru/, and the documentation that used to live at
    getstarted.sailthru.com (now unreachable — TLS handshake failure) and
    getstarted.meetmarigold.com is served from
    products.zetaglobal.com/sailthru/. api.sailthru.com itself still answers
    API calls, but a bare GET of its root now 302s to the documentation site.
