Invitation and sign-in settings appear for public apps with login enabled. If you see No emails yet, check Settings → Login. “Public” apps can still require people to sign in.

Edit an invitation or sign-in email
- Select the Invitation or Sign-in card. Sign-in opens Sign-in email.
- Update the subject, heading, and message. Use the available variables to include details such as the app name.
- For an invitation, you can also edit the Button label. The sign-in code email has no Button label. The code itself is not editable; each email carries a fresh code.
- Review the preview, save your changes, and send a test email before inviting customers.
Invitation links expire after 7 days. Sign-in codes expire after 10 minutes. An app starts sending codes only when you next republish it. Existing sign-in links keep working. Invitation emails still use a link. Do not forward invitation links or sign-in codes to someone else.
