Continuous Domain & Email Posture Monitor
A SaaS that continuously monitors personal and small business custom domains. It tracks DNS records, SPF/DKIM/DMARC validity, WHOIS privacy status, and TLD reputation to prevent domain hijacking and email spoofing.
為什麼這很重要
You rely on a custom domain for your primary email, meaning your entire digital life is tied to it. If someone compromises your registrar or alters your DNS records, they control your password resets across all services. Setting up a secure stack with separate registrars, DNS managers, and email hosts requires precise configuration of complex authentication records. Existing guides tell you what to do, but no tool actively watches your configuration to ensure your privacy protection hasn't lapsed, your authentication records haven't broken, and your emails aren't silently dropping into enterprise spam folders because of a poor domain reputation.
- · 專為 Privacy-conscious individuals, solo developers, and small business owners who use custom domains for critical accounts. 打造。
- · 最可能的變現方式：SaaS subscription (freemium model)。

為什麼這件事可能失敗
自我反駁——最重要的信任度信號
- 1Users may view domain security as a 'set it and forget it' task, refusing to pay a recurring subscription for ongoing monitoring.
- 2Major registrars or DNS providers could release a comprehensive dashboard that makes third-party monitoring obsolete.
- 3The tool might struggle to accurately diagnose complex deliverability issues, leading to user frustration if emails still go to spam.
