At Mailhardener we built a BIMI validator tool [0], we also work with the AuthIndicators Working Group (the authors of the BIMI standard) to refine the standard. Please be aware that the BIMI standard is far from finished. There are some serious documentation ambiguities that pose a risk to how well BIMI might function, and how email providers will adopt the technology. Obviously, the CAs are now pushing hard for BIMI, since VMCs are a new source of recurring business for them. In my personal opinion I think that BIMI is pushed to early, which could leave brands attempting to adopt BIMI disappointed. Obtaining a VMC is quite involved (and expensive) for small businesses, and the potential benefits are (currently) quite small, as not many email service providers support BIMI. Don't get me wrong though, I think BIMI has a great goal of pushing the DMARC adoption rate (remember, you must implement strict DMARC for BIMI to work). I just don't see BIMI offering any reliable brand exposure for the coming years. Only time will tell I guess.
