Hi Malik! Thanks for reaching out.

It sounds like there are two things going on here:

1. Missing left navigation panel - You can expand the left sidebar by clicking the expand button at the top of it. Once expanded, scroll to the bottom and click "Navigation Settings" to customize what appears in your nav.

2. Enabling Newsletter - The Newsletter feature does need to be enabled. We'll get that turned on for you shortly!

In the meantime, once it's enabled, you should be able to find it directly in your left navigation panel. Let us know if you have any other questions!
