About
Sentinely exists because the evidence already arrives every day — trapped in XML nobody reads. We turn it into something a person can act on.
You publish a single DNS record. From then on, mailbox providers worldwide send us the DMARC aggregate reports for your domain. We parse them, resolve every sending source, check authentication, alignment, record syntax and blocklist status, compare your DNS with the previous observation to catch what changed, and return a verdict: a 0–100 score with a grade, alerts, a digest and reports you can export.
Marketing teams who need their campaigns to authenticate and to know which platforms send in their name. IT and security teams taking a domain from p=none to enforcement. And the agencies, MSPs and consultants who do both, for many clients at once — multi-tenant, white-label, with a read-only API.
Sentinely reads aggregate reports. It is not a mail gateway, it does not test inbox placement, and it never touches your DNS. We would rather tell you what it doesn't do than have you find out later — so the limits are written down next to the features, on every page.
