To view Direct Mail campaigns that have already been created/are active, you'll just have to follow these steps:

1. Head to the "Campaigns" tab. On the top of the page, you'll see a "Direct Mail" tab. This is where you'll want to go.
2. From here, you'll see all of your Direct Mail campaigns!

When your campaign has gone live, you will be able to access your campaign stats, including shipping updates, tracking numbers, and whether the mailer has been delivered.
