In their own words
Mail-Tester
Mail-Tester checks an email, its mail server, and sending IP, then gives a spam score and reports configuration findings. To run a test, send a message to an address generated by the service and open the result page. Checks include blocklists, SpamAssassin, SPF, DKIM, Sender-ID, DMARC, links, and pictures. The free plan allows three tests within a rolling 24-hour period. A test counts after a new message is sent, the result page is requested, and the result is returned successfully; reopening that result does not use another test. Free results remain available for 7 days. With an account using its own prefix, results remain available for 30 days. Accounts also provide white-labeling, result-page CSS customization, statistics, a 30-day test listing, and pages without ads. Paid plans include an iframe and JSON API for integration; API output can include message details, authentication checks, body analysis, blacklist results, and broken links. One-time test bundles cost $5 as a one-time purchase to $250, paid once; monthly plans cost $10 a month to $250 a month. Passing does not guarantee inbox placement.
