Mass Disable Email Notifications for Experience Site Users in a Particular Site

 Chatter email notifications can be toggled for Experience Site users by performing an update operation on the NetworkMember object using Data Loader.
 

The following steps describe how to export the current email notification settings for Experience Site members using Data Loader, modify the PREFERENCESDISABLEALLFEEDSEMAIL field (which controls whether all Chatter feed emails are disabled for a member — TRUE = disabled, FALSE = enabled), and then re-import the updated file to apply the changes at scale.

1. Export the CSV file via Data Loader. Make sure that you include and select the following fields so they're included in your export file as columns on the spreadsheet:
 

 - ID - This is the Id of a user in a particular site; this is necessary to perform an update

- PREFERENCESDISABLEALLFEEDSEMAIL - Can only have the value of TRUE or FALSE. By setting the field's value to TRUE you are effectively performing the same action as deselecting the "Receive emails" preference via the site member's Chatter Email Settings; this is necessary to perform an update

- NETWORKID - This is the ID of the site, this field cannot be updated but is helpful to determine what site the member is a part of

- MEMBERID - This is the User ID of the site member, this field cannot be updated but is helpful to determine which user you're updating

2. Modify the file according to your preference. Some permissions can also be toggled by looking at the NetworkMember table.


3. Mass Update the NetworkMember table using Data Loader.
