The “Finalize” feature allows you to move a response from the Incompletes tab to the completed Response tab, closing the response and preventing further edits by the respondent. We’ve updated the feature to automatically send responses through connectors (except PayPal) and to send any configured email notification.
“Finalize” does not run the PayPal connector, which requires the respondent’s presence. In addition, the “Finalize” option does not send the auto-responder, as we think it would be confusing for the respondent to receive this email without having finalized the form themselves. However, we welcome your feedback on this and are open to changing it. You can let us know via the UserVoice forum, Twitter, or send us an email.
