BIMI is really cool. I played with it, setup the appropriate DNS records, created an SVG logo and ... well that's about where it stopped as registering a trademark is a bit of a step too far for getting all of this to work.

It does pass the checks though [1], but does not really work because of the missing certificate which you can for example get at DigiCert [2] once your trademark has been approved..

The domains I configured it for are: antwise.com and vimalin.com so you can see at [1] how it looks like when it is supposed to work.
