Wow, #Slack is either nefarious or negligent, or both.
The "Unsubscribe" link in their marketing emails is broken (it is an HTML anchor tag with no HREF attribute), and in violation of the US CAN-SPAM Act of 2003, which states:
> A visible and operable unsubscribe mechanism is present in all emails.
What's worse (and unsurprising): they hide the email settings behind layers of UI obfuscation.
