Check the following...

1. Some email providers sort emails automatically into different categories, like Primary, Social, Promotions, and Junk. Make sure your regular mail is not being mistakenly categorized as something other than Primary. Look for a way to customize or adjust the sorting rules.
2. Check if you have accidentally marked your regular contacts or senders as spam or junk. This might cause your email app to filter those emails away from your regular inbox.
