There's definitely room to improve in the products (ie I think Slack's recent scheduled messages are a good improvement towards this), but personal discipline goes a long way here, especially when frequently the product/company goals (pumping engagement) are the inverse of your own. You need to set your own boundaries, and not allow these devices/services to dictate so much of your attention (I say as I procrastinate on HN). Use app or OS features to mute notifications. Sign out. Wait before replying. Leave your phone behind. 99 times out of 100 you can definitely just wait before checking and replying.
