In Salesforce Chatter is a great way to boost collaboration in your organization. The user can Post Status, Links, Files, and comments on others post. We can also add any number of users in Chatter group. Chatter can email you every time someone follows you, posts to your profile or groups, etc. You can also receive daily or weekly Chatter group email digests for the group you are a member of as well as a Personal digest (It contains posts from your feed and up to 3 comments per post). To receive Chatter email notification and digests System administrator has to enable email notifications for your organization. By default Personal digest is set to Daily and New Chatter groups I join Digest is set to None for new users.

Business Use case

Tamara McCleary is working as a System administrator at Universal Containers (UC). She has received a requirement to auto update new user’s Chatter email settings as mentioned below

1. Frequency for personal digest: – Weekly
2. Default frequency for groups I join: Email on each post

Solution for the above business requirement

There are multiple solutions possible for the above business scenario. You can either use Apex trigger, a combination of Flow and Process Builder, and few more. We will use Process Builder to solve the above business requirement. Before proceeding you have to understand User objects in Salesforce.
A) DefaultGroupNotificationFrequency: – This field represents the default frequency for sending the user’s Chatter group email notifications when the user joins groups.
B) DigestFrequency: – This field represents the frequency at which the system sends the user’s Chatter personal email digest.

Possible options for Notification Frequency are
–> Daily Digests
–> Weekly Digests
–> Email On each post
–> Never

Follow the below instructions to create a Process for the above business requirement

1.  Click on Name | Setup | App Setup | Create | Workflows & Approvals | Process Builder
2. To create a new process from scratch, click on the New Button available on Process Management page, A popup will open where you have to enter Name (Enter Update Chatter Email Notification as name), API Name and Description as shown in the below screenshot
