Fraudmarc vs Unspam.email

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.

Unspam.email is an email deliverability platform for examining spam signals, sender authentication, blacklists, previews, and inbox placement. Spam tests assess authentication, sender reputation, blacklists, and message content, then show which checks affected the score. Inbox placement tests send a campaign to seed mailboxes at Gmail, Outlook, Yahoo, and other providers and report where it landed. Email previews cover rendering across more than 50 real clients and devices in light and dark modes. Scheduled tests can track placement and spam scores and send alerts by email when results decline. Its API has 39 endpoints across seven areas and can test mail sent through SES, Postmark, SendGrid, Mailgun, or a sender’s own SMTP setup; an MCP server lets compatible AI clients run tests and retrieve results. The free plan includes 21 tests per month, unlimited sender accounts, and 14-day data retention, but excludes DMARC monitoring and full API access. Custom costs $5 a month, with a $5 monthly minimum and pay-per-test rates.
