Since it’s impossible to stay logged in to Salesforce around the clock, Chatter sends email notifications when something important happens in your feed. You can specify when you want to receive emails so you get instant alerts about key posts to your profile or in important groups. You can even choose to receive a daily or weekly digest for a quick recap of what’s new in your company.
Stay in touch more easily with email notifications about your feed. Choose the frequency and scope of the alerts, such as whether or not you’re notified of new followers, new posts on you profile or in your groups, or new comments on your status updates.
Keep up with Chatter even when you’re not logged in. You can get a daily or weekly Chatter email digest of all the posts from your feed and/or the feeds from your groups.
