> unsubscribing you automatically
What is this magic? I've never once been automatically unsubscribed from anything.
To be fair, this is the kind of thing where, if it had happened, it’s possible you wouldn’t have ever noticed.
Google, in particular, will send all a sender’s mail to everyone’s spam folder if it sees low engagement across all gmail users... so it is in publisher’s own self interest to remove disengaged users.
