Increment of "Times Used" field in Email Templates

The "Times Used" field on an Email Template increments when the template is used through the following methods:

1. Activities — When the email template is selected and used through the Send Email action on an Activity (Task or Event).
2. Flows — When the template is used within an Automated Flow that includes a Send Email action.
3. Apex Code — When the template is referenced and used in Apex code to programmatically send an email.
4. Triggers — When an email is sent using the template via a triggered action in a workflow rule or custom Apex trigger.

Important: The "Times Used" field does not increment when the template is used in Email Alerts configured within workflow rules or Process Builder. This is expected behavior — Email Alerts process the template differently and do not update the counter.
