The company lists 167 Madison Avenue, Suite 205, New York, New York 10016, United States, and a Barcelona office.
What it is
Unspam.email helps marketers and product teams assess email deliverability through spam checks, inbox placement tests, previews, and monitoring. Spam tests evaluate authentication, sender reputation, blacklists, and content, then show which checks affected a score. Inbox placement tests send campaigns to seed mailboxes at Gmail, Outlook, Yahoo, and other providers and report where messages landed. Email previews show rendering across more than 50 real clients and devices in light and dark modes. Scheduled tests can track spam scores and placement, with email alerts when results decline. Its API has 39 endpoints across seven areas and can test messages sent through SES, Postmark, SendGrid, Mailgun, or a sender’s own SMTP setup. Compatible AI clients can use its MCP server to 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. Submitted email content and headers are stored to provide the service; AI-generated reports send test content and results to OpenAI, where they may be retained for up to 30 days and are not used for model training.
