Access to the branding panel is reserved for admin-level users.
You can edit the branding and company logo to suit the look and feel of your company website, colours, and logo. This branding will display on public pages, like the unsubscribe page, update profile pages, when viewing online versions of your mail, or the complaints page. The logo inside the platform will only change for Enterprise accounts.
To make these adjustments, hover over your username and click Branding. This will open the branding panel of your install, for the customer you’re logged in as. If you’re not able to access branding for your customer, you don’t have administrator permissions.
