If you want to get the attention of a specific person, type @ followed by their name to mention them. As you type, a menu will appear, listing the members in your group that match that name. Select the member you want and then click post or start. You can mention people in comments, thread contexts, or in the details of a decision. They will be notified that you’ve mentioned them.
When you reply to a comment, the author of the original comment will be notified of your reply.
Reactions are for sharing how a comment made you feel, or acknowledging something someone has said, without writing a comment. React by clicking the 😃 emoji button beneath any comment thread context. They’re an unobtrusive, light-weight way to participate without interrupting the conversation.
Reactions send a notification within Loomio, but do not send an email.
Invite to thread
If the thread is an important announcement and contains information that’s ready for the whole group to take notice of, you can notify people with the invite to thread screen. People you notify will get an email immediately with the title and context of the thread included.
Inviting guests and experts to the thread.
If you want to involve people who are not in your group (or not on Loomio yet) you can invite them into the thread by entering their email address. They won’t get access to the rest of the threads in your group; just this one. (If you do want them to be in the group, then invite them to join from the group page).
