Gmail: Legitimate JotForm emails sent to spam folder

Hello, some of the emails sent from the form are being sent to spam folder. i'm using gmail account as receipient.

Our emails usually work well with the @gmail inboxes. I would like to suggest marking the message(s) as 'Not Spam', it should train the system to detect the legitimate emails properly in the long term.

There is also an article in Gmail support:
