Unmeasured means there is not enough evidence to decide. How these checks work
Start using io.github.serg-tanichev/email-spam-tester
Choose your client, copy the configuration, then enable the server in your client’s MCP settings.
Run this command in your terminal, then restart Claude Code.

The message exactly as it was received: headers, both bodies, source. Useful when a finding points at a header and the agent needs to see what it actually sent rather than what it believes it sent. The message is kept for an hour after it arrives and then deleted; within that hour anyone with the slug can read it. After that only the report remains.
DiscoveredRead a report by its slug without waiting, with provider placement so far. The report stays at its link for good and anyone with the link can read it: the checks, the score, the fix plan, and the subject and sender of the email.
DiscoveredReserve a single-use address to send a draft email to, for a full check. Returns the address and the URL its report will appear at. The address accepts exactly one message and expires after an hour. The email has to be sent by the person, from the platform or mailbox they really send from: half the checks read what that platform adds. The report covers 42 checks (SPF, DKIM, DMARC, reverse DNS, TLS, blocklists, content, links, the Gmail and Yahoo bulk-sender rules) and a plan of what to fix. lang is decided now because the message arrives minutes later over SMTP, which carries no hint of who is waiting for it. What wait_for_report returns quotes check lines in English whatever it is set to; the person following report_url sees their own language.
DiscoveredWait until the message arrives and has been analysed, then summarise it. Call it after the email has been sent to the address from get_test_address. Blocks rather than returning "not ready yet": an agent told to poll writes a sleep loop and usually gives up before the analysis finishes. Provider placement keeps filling in for up to 30 minutes after the report; get_report reads the latest.
