Wow. They clearly stated why they were generally tracking the messages, so that they could show that somebody read the message about all your files being deleted. You could argue that they should go out-of-band (phone call, registered letter) but that gets into weird situations (customer has died, employee was fired). I'm using Firefox with uBlock Origin, a Pi-Hole equivalent, etc. I get wanting to protect your privacy but this seems reasonable. If it really bothers you, have images turned off in your email by default. No relationship to Backblaze other than buying a second account for my in-laws since they don't know how to back up their Windows machine.
