AUTHPROBLEM.comEmail Authentication Analysis

Privacy Policy

When you use this site, we process the information you submit, such as domain names, selectors, email-authentication details, contact-form content, and any email address or IP address supplied for a sender test. We also process basic technical data such as request time, source IP address, request identifiers, browser security signals, and lookup results so the service can operate, diagnose faults, prevent abuse, and produce operational reports.

Form submissions are checked using Cloudflare Turnstile for spam prevention. Contact form submissions are sent using the AuthSMTP email service provider. Those providers may process technical request data and message content as part of delivering, protecting, and securing the service.

We do not sell submitted lookup data or contact-form content. Information may be retained in service logs or email records for troubleshooting, abuse prevention, security, and operational monitoring, and may be shared where necessary with service providers or where required to investigate abuse or comply with legal obligations.
