Mail Tester
Newsletter spam test by mail-tester.com
Mail Tester analyzes outgoing emails to estimate their spam score and deliverability quality, checking authentication records such as SPF, DKIM, DMARC and BIMI. Users send a message to a provided address to receive a report on the email's configuration.
The service includes free tools for SPF, DKIM, DMARC and BIMI checking and generation, along with a domain scanner, DNS record lookup, phishing link checker, DMARC report analyzer and IP reputation check. Accounts add integration options through an iframe or JSON API, customizable result-page CSS, white-labeling, test statistics, and a 30-day test history.
It is aimed at individuals and teams managing email authentication, with a free web interface for occasional manual tests. Paid options are packaged as monthly subscriptions or one-time test bundles, with pricing based on the number of tests included.
