I think it could be interesting to offer a “Simple” mode and an “Expert” mode. Less experienced users could receive clear explanations and easy-to-follow recommendations, while those with more experience could access the technical details behind each alert, such as SPF, DKIM, DMARC, Reply-To, domain reputation, and other indicators. This way, the extension could adapt to different levels of knowledge without overwhelming beginners or falling short for more advanced users.
