To alert users to new activity in conversations they follow, Yammer sends notifications either by email, or—for users with mobile devices—through push notifications.
To avoid overloading users with notifications, Yammer generates email or push notifications only when users don't go to Yammer to read the new message after a specific delay interval.
If you received a notification but didn't respond by reading the new activity on Yammer, you won't receive further notifications for the same thread. This prevents notifications from piling up when you are away from Yammer for a length of time.
When are email and push notifications sent?
Email notifications and push notifications are sent when:
A new group announcement is posted.
Someone mentions you on Yammer.
Someone is added to a direct message.
A non-group participant is added to a private group conversation.
A message thread conversation in your Yammer Inbox goes from read to unread.
Someone replies directly to your message.
Someone sends you a new direct message.
Q: How does an All Company announcement differ from a group announcement?
A: All Company announcements are immediately sent to all users' Yammer Inboxes and to all users via email regardless of their notification settings. Group announcements will also immediately generate notifications to the Yammer Inboxes of all group members, but will only send email notifications to users who have their notifications settings to email when they receive content in their Yammer Inbox.
Q: What is the notification delay logic?
A: The length of the notification delay interval (the time Yammer waits for a user to read new content before sending a notification) depends on whether the user accesses Yammer from a computer or a mobile device.
If a user is on a computer and is active on the web, email notifications are delayed for 15 minutes. Notifications to users on mobile applications have a 20-minute delay.
Q: When does a thread become an unread push notification?
A: A push notification (subject to delay logic) goes out when there is activity on any Yammer Inbox conversation that makes the thread state change from read to unread AND is not a direct reply, an @mention, or a private message.
Q: Can I still post to Yammer via email?
A: Yes, you can still forward an email to a group, and you can reply to a notification email. Use the address (network_name)+(group_name)@yammer.com.
Q: I'm subscribed to a group via email. What happens to the group subscription?
A: For email subscriptions, Yammer delivers new conversation previews, direct replies, @mentions, and messages that make a thread go from read to unread in your Yammer Inbox. An example would be a reply to someone else on a thread you had previously read.
Q: Can admins set default email settings for a network?
A: No, the admin can only toggle the frequency of the digest email for users created after the setting change. Users can tune their own notification settings.
