Email client focused on reducing phishing risk and inbox overload

I was getting tired of looking at emails, and asked to respond to malicious emails by friends and family. So I started trying to build a solution that could be offered to them since I couldn't find a consumer product that did the same. I have been building this firstly around an AI trust layer to help my parents recognize what is spam and malicious emails and then to reorganize emails around relationships and context. I am about to invest in a CASA tier 2 assessment to finish out the Google Oauth process and am interested in hearing thoughts around the problem itself, the approach, and concerns that there might be around the security model. I dabble with security and genuinely just want this to turn into something that can be used by the general public and teach everyone over time what to look for so finding a cybersecurity expert that can help take this further would be amazing!
