Workspace branding
Eligible plans can use a workspace logo, restrained accent color, and sender label on delivery pages. Branding does not hide Astral's safety, access, or expiry information.
Use authorized assets
- Upload a logo you are allowed to use.
- Keep sender text accurate.
- Do not imitate another organization or make a delivery look like a system security prompt.
Custom domains
A custom delivery domain belongs to the customer, such as files.example.com. astrls.com remains Astral's own primary domain. Domain verification and TLS must complete before links are published on that hostname.
