What Red Sift DMARC (BYOK) is for

Red Sift DMARC (BYOK) lets an AI assistant read your own Red Sift DMARC data through the Red Sift DMARC API with a key you supply (OnDMARC API key (business-tier add-on; only super-users can view keys)). Read-only: 9 tools (list_domain_names, list_domains, list_tags, list_dmarc_guardian_issues, list_reporting_domains, list_email_sources, get_delivery_statuses, get_dmarc_results, list_dns_changes). The BYOK key travels with each request, is used for that one call only and is never stored, logged or cached; it is only ever sent to rpc.redsift.cloud. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Red Sift DMARC. Red Sift DMARC and its logos are trademarks of their owners and are used only to say which service the connector works with.

Ask your assistant things like:

  • "Which domains are in my OnDMARC account?"
  • "Which of my domains have a DMARC policy problem in OnDMARC?"
  • "Which domain tags exist in OnDMARC?"
  • "What DMARC Guardian issues are open on my domains?"
  • "Which domains reported DMARC data recently?"
  • "Which email sources are sending unauthenticated mail for example.com?"

What it does

  • list_domain_names: List the domain names in the OnDMARC account (names only; use list_domains for details).
  • list_domains: List domains with DMARC and DNS status, tags, notes, last update and email volume statistics. Optionally filter by domain names or a volume date range.
  • list_tags: List the account's domain tags with title, colour and description.
  • list_dmarc_guardian_issues: List active DMARC Guardian issues (detected email authentication problems) across the domains the key can access, with the affected domain and notes.
  • list_reporting_domains: List domains that have sent DMARC aggregate or forensic reports to OnDMARC, with first and last report times.
  • list_email_sources: List classified email sending sources (IPs and hostnames) with classification (valid, invalid, forwarder, unknown, misconfigured), domain and validation status.
  • get_delivery_statuses: Get daily DMARC delivery counts (total, pass, and failures by disposition none, quarantine, reject) for a date range, optionally for one domain.
  • get_dmarc_results: Get DMARC results grouped by SPF and DKIM configuration (alignment modes, disposition, results, selectors) with message counts for a date range.
  • list_dns_changes: List DNS record changes (SPF, DKIM, DMARC and others) across the account with record type, new and previous value, severity and time.

BYOK key

You bring your own Red Sift DMARC OnDMARC API key (business-tier add-on; only super-users can view keys) (https://docs.redsift.com/ondmarc.yaml). Your assistant sends it in the X-Upstream-Key header with each request. ConnectorBay uses it for that one call only: it is never stored, logged or cached, never shown in an answer, and it is only sent to rpc.redsift.cloud over https, with no redirects followed. Create a key with the fewest permissions the tools need (read-only if the provider offers it), and revoke it at the provider whenever you like.

Data sources

Live from the Red Sift DMARC API (rpc.redsift.cloud) with a BYOK key; documentation: https://docs.redsift.com/ondmarc.yaml. Endpoints checked against that documentation on 2026-10-16.

What it is not

Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Red Sift DMARC. Red Sift DMARC and its logos are trademarks of their owners and are used only to say which service the connector works with. It is read-only: it never creates, changes, sends or deletes anything in your Red Sift DMARC account.
