Highend contact form no longer sending email

The contact form from the theme has worked fine for 4 years but it’s no longer sending emails to my email acct. I tried updating the theme and that didn’t solve it. I also tried using several other email addresses including a basic gmail address and none worked so its not on the email side. In frustration i created a new contact page using “blank template” and droped in a contact for 7 form, and for some reason that wont work either. Again, I tried. several email addresses.
