Could you go to the Feedback menu in your dashboard, and check if the forms submitted by visitors are displayed there?
If they are, it is most likely because your server is not configured properly to send emails through WordPress’ wp_mail function, which Jetpack uses.
Can you try installing the Check Email plugin and sending yourself a test email to see if it works? You can download the plugin here:

If you didn’t receive a test email, you could try using a plugin like this one to configure your WordPress site to use a third party email provider instead of your server’s email functions:

If the function appears to be work properly, it means that Jetpack’s emails are filtered out before they can reach your inbox:
- They can be filtered out by your server before they even get sent out; your hosting provider should be able to check their server email logs to find out if the emails were blocked.
- They can be filtered out by your email provider. If you don’t find the emails in your spam folder, you might want to try to send out Jetpack emails to another email address, and see if you keep experiencing issues. You can do so thanks to this option in the contact form builder:
