Make an announcement

Slack has several ways to send announcements, whether in a specific channel or for your entire team. Just type in the appropriate @mention with your message, then send.

@here

The @here mention lets you notify just the team members in a channel who arecurrently active in Slack.

@here is best for sending announcements relevant to team members that are currently working or available.

@channel & @everyone

The @channel and @everyone mentions can be used to trigger desktop and push notifications for several team members at once.

• @channel will send a notification to all team members in the channel where you post the message.
• @everyone notifies every member of your team. This command can only be used in the team-wide channel (usually called #general).
• Notifications will be sent to all team members in the channel whether they are active or away.

When you use one of these @mentions, Slack will confirm the number of people you’ll notify and how many time zones are affected before sending the message.
