io.inboxguard/email-deliverability

Official28 tools

Scan and fix a domain's email deliverability (SPF, DKIM, DMARC, MTA-STS, BIMI, DNS blocklists).

Scans and fixes email deliverability issues including SPF, DKIM, DMARC, and DNS records.

Captured live from the server via tools/list.

scan_domain

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. Runs at your plan tier (full blocklist set on paid plans) and saves the scan to the domain history in your account.

Parameters (2)

domainstringrequired
Domain to scan, e.g. example.com.
dkimSelectorsarray
Optional DKIM selectors to probe.

get_deliverability_score

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

Parameters (1)

domainstringrequired
Domain to score, e.g. example.com.

check_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).

Parameters (1)

domainstringrequired
Domain to check, e.g. example.com.

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.

Parameters (2)

domainstringrequired
Domain name tracked in the account, e.g. example.com.
daysinteger
Lookback window in days (default 30, max 90).

list_domains

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

No parameters.

get_domain

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.

Parameters (1)

domainstringrequired
Domain name as tracked in the account, e.g. example.com.

list_alerts

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

Parameters (3)

resolvedstring
'false' = open alerts only (default), 'true' = resolved only, 'all' = both.
severitystring
Filter by severity (default 'all').
limitinteger
Max alerts to return (default 50).

list_scans

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

Parameters (2)

domainstring
Optional: restrict to one tracked domain by name, e.g. example.com. Omit for all domains.
limitinteger
Max scans to return (default 20).

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.

Parameters (2)

alertIdstringrequired
Alert UUID, from list_alerts or get_domain.
resolvedboolean
true (default) marks the alert resolved; false reopens it.

get_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.

Parameters (1)

domainstringrequired
Domain name tracked in the account, e.g. example.com.

apply_dns_fix

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.

Parameters (3)

domainstringrequired
Domain name tracked in the account, e.g. example.com.
connectionIdstringrequired
The connectionId from get_dns_fix_plan.
opsarrayrequired
The `ops` array from get_dns_fix_plan, passed verbatim. The server validates each op against a freshly recomputed diff before executing.

analyze_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.

Parameters (4)

messagestringrequired
The raw email — full RFC 5322 message, or at least the headers block (Received, Authentication-Results, DKIM-Signature, From, …).
senderIpstring
Optional: connecting IP to evaluate SPF against (overrides the IP parsed from Received headers).
helostring
Optional: the SMTP HELO/EHLO domain.
mailFromstring
Optional: the envelope MAIL FROM (return-path) address.

scan_domains_batch

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.

Parameters (1)

domainsarrayrequired
1-50 domains to scan, e.g. ["example.com","acme.com"].

get_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.

Parameters (1)

jobIdstringrequired
The jobId returned by scan_domains_batch.

remove_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.)

Parameters (1)

domainstringrequired
Domain name tracked in the account, e.g. example.com.

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.

No parameters.

create_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.

Parameters (4)

kindstringrequired
Channel type.
targetstringrequired
Destination matching `kind`: the webhook/Slack/Teams URL, PagerDuty integration key, phone number (E.164), or email address.
displayNamestring
Optional label for the channel.
severityFilterarray
Which alert severities to deliver (default ["critical","warn"]).

create_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.

Parameters (1)

domainstringrequired
Domain name tracked in the account, e.g. example.com.

connect_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.

Parameters (2)

keystringrequired
The SNDS access key from the SNDS Automated Data Access page.
labelstring
Optional label, e.g. "prod sending IPs".

get_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.

No parameters.

get_snds_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).

No parameters.

connect_inbox_placement

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.

Parameters (3)

providerstringrequired
Inbox-placement vendor.
apiKeystringrequired
The vendor API key.
projectIdstring
GlockApps project id (required for provider=glockapps).

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.

No parameters.

start_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.

Parameters (1)

subjectstring
Optional subject line to associate with the test.

get_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.

Parameters (1)

testIdstringrequired
The testId returned by start_inbox_placement_test.

list_inbox_placement_tests

List recent seed-list inbox-placement tests for the org (most recent first) with their status and Inbox/Spam/Missing scores.

No parameters.

get_deliverability_report

Return a structured deliverability report for a tracked domain: the latest score + letter grade, each check's status (pass/warn/fail), the top issues to fix, blocklist count, and DMARC policy. Includes `pdfUrl` — the same auth-gated endpoint that returns a branded one-page PDF (send your bearer token). Use this to summarize a domain's posture or hand a client a report.

Parameters (1)

domainstringrequired
Domain name tracked in the account, e.g. example.com.

get_portfolio

Org-wide deliverability rollup across every monitored domain: average score + overall grade, the grade distribution (how many domains are A/B/C/D/F/unscored), total open alerts, the domains needing attention (lowest score / open alerts first), and a per-client-group breakdown. Use this for an at-a-glance portfolio health summary across an agency or multi-domain account.

No parameters.
