How to prevent emails from my forms going into my spam?

Buongiorno, 

ho creato un  modulo da con autoresponder al cliente ( email ) ma questo va nella casella SPAM come posso risolvere il problema ?

Grazie

Depending on the mail service you are using, you should be able to simply mark one of the emails as "Not Spam".  From then on, emails from that specific address, should no longer be filtered as spam:

If that solution does not work, here is a bit more in depth guide on setting up your notifications/autoresponder to prevent bounce related issues:
