Enquiries
The Enquiries screen appears only when your site has a form that can accept public submissions. Each form has its own table because different forms may ask different questions.
New messages carry an unread marker and add a count beside Enquiries in the dashboard sidebar. Opening the screen marks them as read. Long answers appear beneath the shorter fields so the message stays readable.
Only someone signed in to your account can read these records. They are not available to public pages or to a connected coding agent. Nothing removes a message automatically. Use the delete control on its row when you no longer need it.
If your site has no form, the Enquiries entry stays out of the sidebar rather than leading to an empty inbox.
