Experience Cloud: Send Email Button Missing from Activity History Related List in Experience Builder Site

Steps to Add the Email Action to the Global Publisher Layout

1. Go to Publisher Layouts:
   1. In Lightning Experience: gear icon > Setup > User Interface > Global Actions > Publisher Layouts
   2. In Salesforce Classic: Setup > Create > Global Actions > Publisher Layouts
2. Click Edit for Global Layout.
3. Drag the Email action from Salesforce Mobile and Lightning Actions on the palette and drop it onto the layout.
4. Click Save.

Additional Permission Requirement

The Send Email profile-level permission must also be enabled for the affected users in order for the Send Email button to appear in Activity History. Without this permission, even if the Email action is present in the Global Publisher Layout, the button will not display for the user.

Verify the Fix

Clear your browser cache and log back into the site. Navigate to a record where the Send Email action was not previously visible and confirm the button is now restored.
