Notifications

Which notifications On-Call Optimizer sends, and how to choose what you receive.

What gets sent

On-Call Optimizer tells the right people about important events, and skips the rest. What matters differs between people, teams and schedules, so you choose which notifications you receive and how.

This page describes how to change your notification preferences and lists the notifications On-Call Optimizer sends.

Changing notification preferences

The bell icon (Open notifications) at the top right of the top navigation bar lists your recent notifications, with a dot on unread ones. Click a notification to see its details, click Mark all as read, or click View all notifications for the full list.

To choose which notifications you receive, and how:

  1. Click the bell icon (Open notifications).
  2. Click the cog icon (Notification preferences) at the top of the Notifications menu.
  3. In the Notification preferences panel, turn each notification type on or off in the Email and Slack columns.
  4. Click Save preferences, or Cancel to close the panel without saving.

Notification methods

On-Call Optimizer can notify you by email and by Slack.

  • Email goes to the address of the account you log in with.
  • Slack is available when your account belongs to an organization that is connected to a Slack workspace and you have connected your Slack account. To check whether Slack is connected, click your organization’s name in the top navigation bar and open the Messaging tab. See Slack.

Until you connect Slack, notifications that are on by default are sent by email. Once you connect Slack, they are sent to Slack instead, and email is off by default. The Slack toggles are disabled when you haven’t connected Slack.

Slack channels can also subscribe to a schedule’s notifications. See Slack.
