Rigcheck is a free tool for checking a domain's email authentication records. It's designed to collect as little as possible.
The domains you check
When you check a domain, Rigcheck looks up its public DNS records. To do that, the domain name is sent to public DNS resolvers operated by Cloudflare and, as a fallback, Google. The results are cached for five minutes so repeat checks are fast. Rigcheck doesn't keep a list of the domains people check.
Accounts and cookies
There are no accounts, and Rigcheck itself doesn't set tracking or advertising cookies.
Hosting and security
The site runs on Cloudflare, which processes technical information such as IP addresses to deliver the site and protect it from abuse, under its own privacy policy.
If you email us, we receive your email address and message and use them only to reply. Mail to rigcheck.dev addresses is forwarded through Cloudflare Email Routing.
Links to other sites
Some guides link to other companies' websites, including affiliate links described in our affiliate disclosure. Those sites, and any cookies they set when you visit, are governed by their own privacy policies.
