## What is DNS Survey?

DNS Survey reads a domain's public DNS records and explains, in plain English, how that domain handles email.

Type a domain and you get:

• A plain-English summary — who hosts the mailboxes, whether sender authorisation (SPF) is published, whether an anti-spoofing policy (DMARC) is in place and how strict it is, and whether outgoing mail is signed (DKIM).

• Third-party senders — the outside services allowed to send email as that domain, with the evidence for each. Shared sending platforms are labelled separately, because they prove mail is being sent without revealing which application sends it.

• Vendors by category — products the domain shows evidence of using, from mailbox hosting and CRM to payments, security and developer tools, each shown with the record that identified it.

• The raw records — SPF, DMARC, MX, NS, CNAME, A, TXT and DKIM, including SPF lookup-limit counting and DMARC policy warnings. Touch and hold to copy any value.

Everything comes from public DNS. The app never connects to mail servers, sends email, or asks for credentials.

Nothing is stored. No history, no cache, no account — a result exists only while you are looking at it.

Detection is best-effort: a match on a verification token means the domain was verified with that service at some point, not that it is in use today.
