Check your mute button.
Check sounds in your settings.

Go to Settings > Sounds
Also make sure you didin't turn on "Do Not Disturb"

Thank you for your reply,

That was the first thing I did when I start not hearing my mail notification sounds,

My sound settings are checked and turned on,

I was playing and exploring my settings yesterday, and I don't know what I tapped and disable that.
