I checked some of your forms and I didn't found any failed log.
Could you share a specific form ID or email address? By doing this, we can help yo better.
In addition, if the related email address has the email log without any error, I suggest you to check your Spam, Junk, Promotion or etc. folders. Because, sometimes email submissions could be placed wrongly in mailbox.
