Email Spam Tester

Email Spam Tester checks an email the way receiving mail servers do, before it goes out to your list.

Ask Claude for a test address and send your draft to it from the platform you normally use. A minute later the card in the chat shows the report: a score out of 100, SPF, DKIM and DMARC with alignment, reverse DNS, TLS, 21 blocklists, links, HTML structure, the Gmail and Yahoo bulk-sender rules, SpamAssassin and Rspamd verdicts and a ClamAV scan. The report ends with a fix plan, and DNS records come ready to paste. Claude can rewrite the draft from there, and you test again with a fresh address.

The same send can also show which folder the email lands in at different mailbox providers (inbox, promotions or spam). Some of those inboxes are public test inboxes, so use a message that is not confidential for that part.

The connector does not send email and cannot see your mailbox or your sending platform. You send the test message yourself, because half of the checks read what your platform adds to it. Reports open only by their link and are kept out of search engines, so a report can be shared with whoever fixes the DNS.
