Currently, the Engage message composer displays the total count of excluded contacts in the "To:" field before sending an email blast. However, there is no direct way to see exactly which email addresses or contacts make up this number without manually exporting the segment from the main Contacts page and filtering it down.

It would be incredibly helpful to make the "(X excluded)" text a clickable link. Clicking this link could open a quick modal preview or directly download a CSV file of the excluded contacts, along with a column showing the reason for exclusion (such as unsubscribed or duplicate record).
