Just because they are not in the spam folder, doesn’t mean they aren’t being marked as spam and dropped by the mail server before they even hit your mailbox.
The steps I would take would be to install the WP Mail logging plugin, switch back to use the ‘broken’ email address and test a couple of form submissions.
Then look in the WP Mail log to see if the email is shown there, if it is, your site is correctly triggering and sending the email over to your mail sever meaning from there its out of your control and you would need to contact the host to have them investigate further.
Generally for email issue we would recommend you switch to a transactional email service, we have some listed here:
Which basically means your sending your mail through their servers rather than your host.
