It’s time to turn off those secret email read receipts.

I subscribe to a lot of newsletters. I read most of them, too. But their authors wouldn’t know it because I’ve disabled the trackers that detect and tell the senders when subscribers open their emails. It’s nothing personal; I just don’t want anyone knowing what I read, when, how many times I read it, the device I read it on, and even where I was when I read it. How about you?
