I am trying to stop the default email notifications for a particular User in salesforce through apex code. Stopping default email notifications can be done manually by going to My Settings -> Email Settings and unchecking 'Receive emails' checkbox. I need to achieve the same thing through Apex code. Please suggest how can this be done?

Have you tried the settings on the NetworkMember object? For Communities, this seems to take precedence. For a similar issue, I poked it via the developer console with this query:

SELECT Id, PreferencesDisableAllFeedsEmail FROM NetworkMember WHERE MemberId = ''

Assuming you are referring to the chatter email settings feature:

You can clear this checkbox by setting the UserPreferencesDisableAllFeedsEmail field to true for the user. In the screenshot above my Receive emails checkbox is set, but if I execute the following Apex code:

User u=[select id, UserPreferencesDisableAllFeedsEmail from User 
      where id=:UserInfo.getUserId()];
update u;

the checkbox is cleared:

  • Thanks for your reply. But I am trying to disable all the email notifications to a Community User. Not only chatter email notifications, but i need to disable notifications for Private messages too. I have tried the above code which you have given but still it is triggering Private message notification email.

  • It looks like the private message email notifications are controlled by the UserPreferencesDisableMessageEmail property on the User sObject.

  • I have set 'UserPreferencesDisableMessageEmail' property to true. Even now the private message email notifications are getting triggered.

  • Wonder where we can find the full list of which API name corresponds to what.. eg. UserPreferencesDisableAllFeedsEmail to toggle the "Receive emails" .. how about <apiname> to toggle the "Mentions me in a post"

Run below code in developer console to disable chatter only for community users.

Profile p = [Select Id,name from Profile where name = 'System Administrator']; 
List<NetworkMember> nmList = [Select Id,MemberId,NetworkId,PreferencesDisableAllFeedsEmail FROM NetworkMember WHERE Member.ProfileId != p.Id];
    for(NetworkMember nm: netMemList){
     nm.PreferencesDisableAllFeedsEmail = true;   
    update nmList;
