Using DKIM Record Generator
Generate and review
Review the generated file before applying it to your domain or server.
Keep the useful details
Copy or download your results. Follow a related tool to continue diagnosing.
Why can a check be unavailable?
Some servers block diagnostic traffic, DNS resolvers time out, or public data providers limit requests. An unavailable check is not a successful result. Try again later or compare with another tool.
Does generating a file change my configuration?
No. Generation creates a file for you to review and install. DNS records must be published by your DNS provider, and server files must be installed on your own website.
