Fraudmarc vs Mail-Tester

Fraudmarc provides brand and customer protection services centered on SPF, DKIM, and DMARC email authentication. It manages and monitors authentication policies and provides free DMARC reports. Its SPF Compression service imports and compresses existing policies, gives users a panel for adding email vendors, and dynamically updates flattened policies when customers or vendors make changes. The service is designed to help address SPF's 10 DNS lookup limit while keeping policies within specification limits. DMARC tools include hosted report analysis, automated analysis, and SenderTrace Intelligence, which identifies people and departments behind email sources. Fraudmarc also lists free SPF record and DMARC policy checkers, and makes its Community Edition DMARC Analyzer available on GitHub. It offers web and self-hosted access. DMARC Standard includes 30-day history for $21 per month when billed annually; Advanced is $4 per user per month billed annually and includes 90-day history. SenderTrace Intelligence is $12 per user per month billed annually and includes one-year history. SPF options start at $2 per month.

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.
