 Email sharing allows you to share your public dashboard with only specific people by email, instead of having it accessible to anyone with the URL. When you use email sharing, recipients receive a one-time use link that's valid for **one hour**. Once the link is used, the viewer has access to the public dashboard for **30 days**.
