The record

Purpose: Unspam is an email deliverability platform that checks spam signals, sender authentication, blacklists, previews, heatmaps, and inbox placement.
Spam tests: Spam tests score messages using authentication, sender reputation, blacklists, and content signals, and identify checks that affected the score.
Inbox placement: Inbox placement tests send a campaign to seed mailboxes across Gmail, Outlook, Yahoo, and other providers and report where messages landed.
Email previews: The service previews email rendering across more than 50 real clients and devices in light and dark modes.
Automation: Scheduled tests can track placement and spam scores and email alerts when results decline.
Integrations: The API can test messages sent through SES, Postmark, SendGrid, Mailgun, or a sender's own SMTP setup.
API and MCP: The API provides 39 endpoints across seven areas, while the MCP server lets compatible AI clients run tests and retrieve results.
Intended users: The company describes the platform as serving marketers, founders, agencies, and product teams.
Free plan limits: The Free plan includes 21 tests per month, unlimited sender accounts, and 14-day data retention; DMARC monitoring and full API access are excluded.
Support: The company lists support chat and [email protected] for support or product inquiries.
Privacy: The privacy policy says submitted test emails, including their headers and message content, are collected and stored to provide the service.
AI processing: For AI-generated reports, Unspam says it sends the submitted test content and test results to OpenAI, where the content may be retained for up to 30 days and is not used to train or improve models.
Security: The privacy policy says stored data is kept on services and providers certified to ISO/IEC 27001:2013, PCI DSS, SOC 1 Type II, and SOC 2 Type II or higher.
