The Responses tab lists every submission with its answers. Use it to see what came in and to keep track of what you have dealt with.

Read responses
Each row is one submission: when it arrived, then one column per field. The tab name shows how many responses there are. Click Refresh to load new ones.
Mark them handled
The Internal column is for your team only.
Click New to mark a response Handled, and again to put it back.
Click Add internal note to write a private note, for example "Replied by email".
Filter the list with All, New or Handled.
The respondent never sees the handled mark or the note. They are also left out of the webhook and the notification email.
Export
Click Export CSV to download the responses for a spreadsheet. The file includes whether each one is handled and its note.
Delete a response
Use the trash icon at the end of the row. Only the form's author and workspace owners and admins can delete responses.
Who can see them
Every member of the workspace can read responses and mark them handled. Editing and publishing the form is limited to its author and workspace owners and admins.
