Emails from form not being sent

Our webflow contact form is not sending submission emails. If we have the submissions go to an outside address, like to a gmail or yahoo account, it won’t receive it. If we have it go to our web email jim@insidecbd.net we won’t receive any to our Outlook mail, BUT we will receive it in our web-based email program privateemail.com (for jim@insidesbd.net). The submissions are showing in the submission data. None of the FAQs have helped. Any ideas?

Thank you.
