How to Use Slack Notification Sounds to Improve Work-Life Balance in Remote Work
The problem with working from home is not that you work too many hours. It's that the hours never close. You stop typing at six, but the laptop stays open on the kitchen table making noises, and every one of those noises pulls you halfway back to work for the thirty seconds it takes to decide it wasn't important.
Thirty seconds is not the cost. The cost is that you were briefly at work again, in your kitchen, at half past eight.
Deciding what gets through
Before touching any settings, write two short lists.
The first is what genuinely needs to reach you after hours. For most people this is honestly one or two things: a page if you're on call, and a direct message from one or two specific people who would only ever message you at night if something was actually on fire. Not your whole team. Not your manager by default, unless your manager is the sort who messages at 11pm about things that could wait, in which case the rule is the conversation, not the software.
The second list is everything that will try to reach you and shouldn't. Channel activity. Threads you're following. Bots. Anyone in a time zone eight hours behind you doing their normal morning work. That last one is the biggest source of evening noise on distributed teams and the easiest to stop feeling guilty about, because nobody sending it expects an answer.
Most people's first list has two items and their second list has everything else. The setup follows from that.
Where Focus modes end
macOS Focus modes are good at one thing: a blunt, scheduled, all-or-nothing cut. Set a Personal Focus that turns on at 18:30 and off at 08:30, allow notifications from the two people on your first list, and you've solved the majority of the problem with a built-in feature and no extra software. Do this first. If it's enough, stop here.
Where it runs out is granularity. A Focus mode allows or blocks per app and per contact. It doesn't know the difference between a message in #prod-incidents and a message in #watercooler, because both are Slack. So if you're on call, or if one specific channel is the only after-hours thing that matters, Focus alone will either let all of Slack through or none of it.
Where sound rules pick up
That's the gap custom sound rules fill. Instead of allowing Slack as a whole, you keep Slack silent by default and give a sound only to the specific things on your first list.
A concrete evening setup:
- Slack's own notification sound set to None, permanently. Every sound you hear comes from your rules, so there is exactly one place to change things.
- A rule matching
#prod-* on a loud, sharp sound. Active all the time, because that's the point of it.
- A rule matching two named people, at moderate volume.
- No other rule with a sound attached after hours.
The result is a laptop that can still be open on the table and still be quiet, which matters more than it sounds. You don't have to perform the shutdown ritual perfectly to get the benefit of it.
The part that isn't software
Two habits do more than any configuration.
Close Slack on your phone at the same time you close the laptop. Sound rules on your Mac do nothing about the device in your pocket, and the phone is where most after-hours drift actually happens.
And when you do get pulled back in at 9pm, deal with it and then close things again. The failure mode isn't the one interruption, it's the twenty minutes of "since I'm here" that follows it.
Setting it up
Chirpy is a native macOS menu bar app for exactly this: rules that decide which notifications make a sound, and which sound. It reads incoming macOS notifications through the Accessibility API on your own machine, so it never signs into Slack and never sees your workspace. Install it, grant Accessibility permission, set Slack's notification sound to None, and write the two or three rules from your first list. macOS 13 or later, $19.99 once with no subscription, 3-day trial without a credit card.
Pair it with a scheduled Focus mode and your evenings mostly take care of themselves. Setup details are in the guides.
