How the tools work
Built to be honest about what they check
Nothing stored
DR results are cached per domain for 7 days to keep the tool free; nothing is tied to you. DNS checks go from your browser to Cloudflare DNS-over-HTTPS. Page checks fetch the URL you enter and return the result; we do not keep it.
Live data
Every result is fetched when you run the check: live DNS, live HTTP responses and registry RDAP data. The one exception is the bulk DR checker, which caches Ahrefs data per domain for up to 7 days.
Clear limits
Each tool says what it cannot see, such as Spamhaus queries from public resolvers or links added by JavaScript.
FAQ
Questions, answered
Are these tools really free?
Yes. No card. Most tools have no signup and no usage counter; the bulk DR checker has a daily limit because each lookup uses paid Ahrefs API credit.
Do you store what I enter?
No. Text tools run entirely in your browser. DNS checks go straight to Cloudflare's public resolver. URL checks are fetched by a Pink Post function and returned to you without being saved.
Why are these tools from an outreach platform?
They are the checks we run before and after every outreach campaign. Pink Post does several of them automatically, such as link monitoring and bounce protection, but you do not need an account to use these.
Can I suggest a tool?
Yes. Email hello@pinkpost.io.
