Unspam Email Spam Checker

Unspam lets users send a test email to a unique testing address generated for each session, then returns a 0 to 100 spam score that reflects likelihood of reaching the inbox rather than spam, based on authentication (SPF, DKIM, DMARC), sender reputation, blacklists, and content signals. The page also describes blacklist checks across major lists, an accessibility (WCAG) check for emails, email previews across 50+ clients and devices in light and dark mode, an AI eye-tracking heatmap, inbox placement tests across 10 seed mailboxes at providers such as Gmail, Outlook, and Yahoo, and automatic scheduled spam and placement tests with email alerts. It also offers free tools for SPF, DKIM, DMARC, BIMI, and blacklist checks, and access to deliverability consultants. The page states a free account includes a monthly allowance of tests, but exact limits are not given on this page.
