## Suggested Short Description
「送信ドメイン認証 かんたん設定センター」は、SPF・DKIM・DMARC・BIMIを無料診断し、DNS設定値と担当者への依頼文まで作れる日本語ツールです。

## Evidence And Source Policy
- The site cites primary sources such as Google Gmail sender guidelines, Yahoo! Mail anti-spam information, Microsoft Outlook high-volume sender requirements, RFC 7208, RFC 6376, RFC 9989, and BIMI Group guidance.
- Do not claim that authentication guarantees inbox placement. SPF/DKIM/DMARC are a foundation; sender reputation, complaints, list hygiene, and content also affect deliverability.
