  • Scan domain deliverability

    Run a full email-deliverability scan (SPF, DKIM, DMARC, MTA-STS, TLS-RPT, MX TLS, BIMI, DNS blocklists) for a domain and return a 0-100 score with per-check findings. A check can come back `not_applicable` (does not apply to this domain, e.g. MTA-STS on a domain with no MX — excluded from the score, not a failure) or `unverified` (could not be determined this scan, e.g. DKIM behind an ESP with a random per-tenant selector like Amazon SES Easy DKIM — never treat as a failure). `scoreSubtitle` exp

  • Get deliverability score

    Return the overall deliverability score and letter grade for a domain (runs a fresh scan).

  • Check DNS blocklists

    Check a domain (apex + MX-host IPs) against supported DNS blocklists and return listings, targets checked, and issues (authoritative-side queries; no public-resolver false positives).

  • Get DMARC summary

    Summarize ingested DMARC aggregate (RUA) reports for a domain tracked in your InboxGuard account: report volume, pass rate, top sending sources, and the rua inbox to publish. The domain must already be added to the account, and the plan must include DMARC ingest.

  • List tracked domains

    List the account's tracked domains with latest scan score, last scan time, and open alert count.

  • Get domain detail

    Full detail for one tracked domain: the domain record, the latest scan with all per-check findings (spf, dmarc, dkim, ptr, mta_sts, tls_rpt, mx_tls, blocklist), recent score history, open/recent alerts, and Google Postmaster stats when connected.

  • List alerts

    List the account's deliverability alerts (score drops, check failures, blocklist listings). Defaults to open alerts only.

  • List scan history

    List recent scans (id, domain, run time, score) across all tracked domains, or for one domain when a name is given.

  • Resolve alert

    Mark an alert resolved (or reopen it with resolved=false). Requires an API key with write/full scope. Resolving an already-resolved alert is a no-op.

  • Preview the DNS fix plan

    Compute the exact DNS-record changes needed to fix a tracked domain's deliverability, based on its latest scan and the org's connected registrar (Cloudflare/Route 53/GoDaddy/Namecheap). Read-only — nothing changes. Returns the `ops` to pass verbatim to apply_dns_fix, plus `manualReview` items that need a human decision (SPF sender list, DKIM keys, BIMI logo). Requires the domain to be tracked, a scan to exist, and a registrar connection covering the zone.

  • Apply the DNS fix plan

    Apply a DNS fix plan to a tracked domain by publishing records at the connected registrar. DESTRUCTIVE: it creates/updates/deletes DNS records. Two-step by design — first call get_dns_fix_plan, then pass its `connectionId` and `ops` here verbatim. The server re-derives the diff from the latest scan and rejects any op that no longer matches, so an agent can never apply arbitrary records. Requires an owner/admin API key with write or full scope. Re-scan afterward to confirm the fix.

  • Analyze raw email headers

    Re-verify SPF, DKIM, DMARC, and ARC from a raw RFC 5322 email (full message or just the headers block). Returns InboxGuard's independent verdict (`ours`), the sender's own Authentication-Results (`theirs`), whether they `agree`, and parsed envelope/headers — useful for spotting forged or mismatched auth results. No account needed.

  • Batch-scan domains (async)

    Queue an asynchronous batch scan of up to 50 domains and get a jobId immediately (avoids the 30s per-call limit). Poll get_scan_job with the jobId until status is succeeded/partial/failed to read per-domain scores. Requires an API key with write or full scope. These scans are NOT added to monitoring or saved to history.

  • Get batch-scan job

    Poll an async batch scan started with scan_domains_batch: returns status (queued/running/succeeded/partial/failed), completed count, and per-domain results (domain, ok, score, grade) as they finish.

  • Remove a monitored domain

    Stop monitoring a domain and delete it (and its scan history) from the account. DESTRUCTIVE and not reversible. Requires an owner/admin API key with write or full scope. (To ADD a domain, run scan_domain with this API key — authenticated scans auto-track the domain.)

  • List registrar connections

    List the registrar accounts (Cloudflare, Route 53, GoDaddy, Namecheap) connected to the org — provider, verification, last-used time — plus the supported providers. Use this to check whether the detect-and-fix loop (get_dns_fix_plan / apply_dns_fix) is available before attempting it.

  • Create a notification channel

    Create a channel that InboxGuard alerts are delivered to: webhook (HMAC-signed), Slack, Microsoft Teams, PagerDuty, SMS, or email. Returns the channel id, and for kind=webhook the `signing_secret` used to verify deliveries. Requires an owner/admin API key with write or full scope.

  • Create a public share link

    Create a read-only public share link for a tracked domain's latest report (anyone with the URL can view it; no account). Returns a `token` and the public `url` (https://inboxguard.io/r/<token>). Requires an owner/admin API key with write or full scope, on a plan that includes public reports.

  • Connect Microsoft SNDS

    Store this org's Microsoft SNDS (Smart Network Data Services) automated-data-access key so InboxGuard syncs per-IP Outlook/Hotmail reputation daily. Get the key from the SNDS Automated Data Access page (https://sendersupport.olc.protection.outlook.com/snds/). Requires an owner/admin API key with write or full scope. Data appears within ~24h of the first sync.

  • Get Microsoft SNDS status

    Report whether Microsoft SNDS is connected for the org, the last sync time + status, how many sending IPs are tracked, and how many are currently blocked by Outlook/Hotmail. Use before get_snds_ip_stats to confirm the integration is live.

  • Get Microsoft SNDS per-IP stats

    Return the latest per-IP reputation from Microsoft SNDS for the org's sending IPs: filter result (GREEN/YELLOW/RED), complaint-rate band, spam-trap hits, message volume, and current block status. Requires SNDS to be connected (see connect_snds / get_snds_status).

  • Connect an inbox-placement provider

    Store the org's seed-list inbox-placement provider + API key (provider: 'mailreach' or 'glockapps'; GlockApps also needs projectId). Enables start_inbox_placement_test. Requires an owner/admin API key with write or full scope.

  • Get inbox-placement status

    Report whether a seed-list inbox-placement provider is connected for the org, which provider, and how many tests have run. Lists the supported providers when not connected.

  • Start an inbox-placement test

    Start a seed-list inbox-placement test. Returns a testId, the seed addresses to mail your campaign to, and (if the provider requires it) a header to insert. After sending to the seeds, poll get_inbox_placement_test for the Inbox/Spam/Missing verdict. Requires inbox-placement to be connected and an owner/admin API key with write or full scope.

  • Get an inbox-placement test

    Poll a seed-list inbox-placement test by testId. Returns status (running/completed/failed) and, once measured, the Inbox/Spam/Missing counts and inbox-placement score (0–100). Call after sending your campaign to the seed addresses from start_inbox_placement_test.
