You can see which campaigns are linked to each of your connected mailboxes directly from the Mailboxes page — useful for understanding which email account is sending for which campaign.
How to View Associated Campaigns
Go to Mailboxes in the left sidebar.
Find the mailbox you want to inspect.
Click the actions menu (⋯) on that mailbox row.
Click View Campaigns.
A dialog will open showing all campaigns linked to that mailbox, each with a status badge (draft, active, completed, etc.).
Opening a Campaign from the Dialog
Click any campaign in the list to open it directly:
Draft campaigns open in the campaign editor.
Active or completed campaigns open the campaign summary view.
