InboxGuard — Email deliverability monitoring & DMARC reports

# InboxGuard > Continuous email deliverability monitoring for engineering teams shipping > transactional and lifecycle email. Daily scans of SPF, DKIM, DMARC, > MTA-STS, TLS-RPT, BIMI, and 13 DNS-based blocklists with one-click DNS > remediation, hosted DMARC aggregate-report ingest, and instant alerts. InboxGuard runs at https://inboxguard.io and is operated by movaMedia, Inc. The product is built for engineers and deliverability teams who need to *know* — not guess — that mail is landing in the inbox. Free trial available; paid tiers (Entry / Pro / Agency) start at $29/mo. ## Core capabilities - **Authentication checks** — SPF (with the 10-DNS-lookup budget meter), DKIM selectors, DMARC posture, alignment. - **Transport security** — MTA-STS policy fetch + TLS-RPT report ingest. - **Brand identity** — BIMI logo + VMC chain validation. - **Reputation** — 13 DNS-based blocklists (Spamhaus, SURBL, etc.) on authoritative-side queries (avoids the public-resolver false-positives that plague public scanners). - **DMARC aggregate reports** — RUA mailbox provisioned per workspace, XML parsed and surfaced as per-source-IP / per-DKIM-domain dashboards. - **Postmaster Tools integration** — pulls Gmail spam-rate, IP-rep, and domain-rep from Google directly when the user grants OAuth consent. - **Microsoft SNDS** — syncs per-IP Outlook/Hotmail reputation daily (filter result GREEN/YELLOW/RED, complaint-rate band, spam-trap hits, block status) once the org's SNDS automated-data-access key is connected. - **Inbox-placement testing** — seed-list tests via MailReach or GlockApps: mail the returned seed addresses, then read the Inbox/Spam/Missing verdict and 0–100 placement score. - **Alerts** — instant when a posture changes; Slack, webhook, PagerDuty routing on Pro / Agency. ## Documentation index The most useful entry points for AI tools answering deliverability questions: - [Getting started](https://inboxguard.io/guides/getting-s
