Posts that are created within spaces are usually curated and sent out with the digest.
Important announcements that need to be sent out can skip the wait by toggling on the 'Send as announcement' switch before posting.
The announcement toggle is available exclusively to moderators of the space.
Toggling on the option will send the contents of the post as an email to all subscribers of the space immediately. Here's what the email looks like this.
As with all posts in spaces, members can reply to the email to comment, or visit the post to interact.
Moderators can also access the announcement feature after creating the post by clicking the menu on each post.
