If you are using Linkedin Groups, you will receive group emails by default. If you need to change the frequency of these group emails, follow the link at the bottom of your emails to Unsubscribe or Manage Subscriptions.
The link will take you to that specific message page.
Note that you can go to a specific group main page by clicking the LinkedIn top menu page in Interests -> Groups . There you can click on the specific group you’re interested in.
Now, at the top of the group page, to the right, you will notice some buttons at the top right:
Member – this is a toggle to sign up or remove your membership to the group.
The “i” – information button will take you to a different page where you can manage your group notification settings.
The “up arrow” – this is the share button for this specific page.
Clicking on the “i” button will take you to the group notification settings page, as shown below.
Here you can choose to get an email for each new discussion or to receive a digest of all activity.
You can also check to allow the group manager to email you and to allow other members of this group to send you messages through Linkedin.
At the bottom of the page, there is a link to your Linkedin Account Settings, where you can adjust your network updates settings.
