- Emails are also categorized by the mode in which they were sent, such as Individual email or email from a workflow, helping you identify the purpose and triggering method
- Each email in the outbox list displays key details including subject, mode of triggering, and the record it originated from
- Record names are shown as clickable links, allowing you to quickly jump to the record for a closer look
- You can only see emails for records you have access to, in line with your role-based permissions
- Filter emails by module or use time-based filters such as Today, This Week, or Custom Range for focused review
- Emails are stored in the Outbox for 60 days
