As part of your launch on Cubby, if your website was built by us, you should have received an invite to cms.cubbystorage.com . Here, you can set up and input your username (usually your email address) and password.
If you never received a welcome email, please reach out to us at support@cubbystorage.com so we can provide you with access. From here, you can configure and edit everything pertaining to your website that isn't covered by marketing.cubbystorage.com (also referred to as your "Storefront"), which covers all things "Cubby Components".
