Unspam.email is a free spam check and deliverability testing tool for email marketers and self-hosted email senders. Its main purpose is to identify issues that could cause emails to land in the spam folder before sending, improving inbox placement.
Main capabilities
- Spam score: Send an email to the tool's generated unique test address and get a score from 0-100 within 30 seconds. The score is calculated from a combination of authentication (SPF, DKIM, DMARC), sender reputation, blacklists, and content signals, and it indicates which checks deducted points and how to fix them. Score ranges: 0-49 is high risk, 50-69 is risky, 70-89 is good, 90-100 is excellent. If core authentication fails, the report is marked as high risk regardless of the numeric score.
- Authentication and blacklist checks: Checks SPF, DKIM, and DMARC records, and queries whether a domain, email address, or IP is listed on major blacklists such as Spamhaus, SpamCop, Barracuda, and others.
- Inbox placement testing: Tests whether an email actually lands in the primary inbox, promotions tab, or spam folder across 10 seed mailboxes at more than 7 providers including Gmail, Outlook, Yahoo, and others.
- Email previews: Preview how an email renders across more than 50 real email clients and devices (Gmail, Outlook, Apple Mail, iPhone, Android, etc.), with support for light and dark modes, to identify issues such as broken layouts, invisible logos in dark mode, and truncated buttons.
- AI eye-tracking heatmap and AI assistant: Provides an AI heatmap of where subscribers' eyes focus, and an AI assistant gives fix suggestions.
- Accessibility checks: Checks color contrast, alt text, heading hierarchy, dark mode rendering, and more according to WCAG rules.
- Automated scheduled tests: Save an email, choose the run date and time, and Unspam automatically sends it, scores it, and notifies you of the results by email. Each run stores and plots the score trend, and it can also be used for automated inbox placement monitoring.
- Other checks: List Unsubscribe header, broken links and short links, domain suffix and age, etc.
