Chatter post does not trigger Chatter email notifications

If Chatter posts do not send Chatter notification emails as expected, and users have their account configured to receive notifications, verify that the CreatedById and InsertedById fields on the FeedItem have the same value.

• CreatedById: The Salesforce User ID of the user who created the post
• InsertedById: The Salesforce User ID associated with the insert operation. During data migrations, this field may be set to a different user (such as an integration user), which suppresses email notifications

Diagnosing the Issue with SOQL

To check the CreatedById and InsertedById values on a specific Chatter post, run the following SOQL (Salesforce Object Query Language) query in the Developer Console Query Editor. Replace <chatter post Id> with the ID of the affected post.

SELECT Id, CreatedById, InsertedById FROM CollaborationGroupFeed WHERE Id = '<chatter post Id>'

If the query results show that CreatedById and InsertedById contain different User IDs, this is the cause of the missing email notifications. Need information on running SOQL queries? The Developer Console Query Editor has all the tools you need. Dive into the Salesforce Online Help to learn how it’s done.

How to Obtain the Chatter Post ID

The Chatter post ID can be obtained from the browser URL when viewing the post. The ID format looks like: 0D5Hx00001PEy0jKAD.

1. Go to the People tab
2. Go to the record pages of the relevant users
3. Get the IDs from the browser URL

You can also store the Chatter post's ID in a variable for use later in a Flow. The values are assigned when the Chatter post is created.

Resolving the Issue

To restore normal email notification behavior, ensure that future Chatter posts are created with matching CreatedById and InsertedById values. If this occurred during a data migration, work with your migration tool or integration to align these field values on migrated posts.
