No, if you care about your users' privacy you would not implement anything which would allow senders to do what you say BIMI enables. This means in our case: If you -- as a sender -- publishes a BIMI logo all you can track is when our logo service is fetching your logo. Which might be exactly once (ie: one time) when you update it. Our MUAs don't fetch BIMI logos from the source. So all it well tell you is 1: Our MTA saw mail coming in from your domain 2: We probably trusted you enough to see if you have a BIMI logo 3: We fetched that BIMI logo 4: A Verizon Media IP connected to your hosting server 5: Our system is alive and working (well, at least it's requesting logos) That's it.
