My favorite thing about Slack is how they've thought of all the little things. My go-to example is that when they send you a notification email, it includes links to silence further emails with a single click.

Obviously, this isn't a big "feature." It's not going to show up on their marketing materials. Nobody will ever say "hey, you should try out Slack because they let you silence emails." But it's this sort of UX philosophy, of anticipating and cleverly solving tiny little annoyances, that make it a really pleasurable product to use.

Isn't this a legal requirement?

Technically the law is only that you have to honor them within 10 days, but I've seen a bunch of sites with one-click unsubscribe nowadays.

It is a legal requirement to allow users to unsubscribe from your email newsletter, yes. What Slack does that is really cool is at the bottom of their notifications email they have:

Snooze these notifications for: an hour, eight hours, a day, three days, or the next week. Or, turn email notifications off. For more detailed preferences, see your account page.

"hour", "eight hours", "three days", "next week" are all links that silence the notifications for discrete periods of time. Pretty neat.

A notification from Slack, a service you use, is not unsolicited commercial email of any kind. From the Wikipedia link:

> It [CAN-SPAM Act] exempts "transactional or relationship messages."

It's not just unsubscribe. They let you turn off emails for an hour, a day, etc. Really convenient if you're generally interested in notifications, but just need a little break.

Another example: when you change your password, Slack will send you a special link to sign-in on mobile so you don't have to type out your new password on a tiny keyboard.

Sadly (though necessarily) that email-a-link thing doesn't work if you turn on 2-factor auth.

No, not on transactional email.
