Hello Applequery1,
We understand you're not receiving Mail notifications. We'd be happy to assist.
For this issue, we have a resource that should help: Use notifications on your iPhone, iPad, and iPod touch.
If the notification settings for your email are correct in Settings, we'd like you to check the Mail Fetch settings. You can find guidance on how to do this under "Check Mail Fetch and Notification settings" in If you can't receive email on your iPhone, iPad, or iPod touch.
If the issue continues, we'd like you to review your settings under Do Not Disturb: Use Do Not Disturb on your iPhone, iPad, and iPod touch.
Also, if your device is on Low Power Mode, this feature will disable Email Fetch. If this feature is being used, we'd recommend disabling and test if the issue continues. Use Low Power Mode to save battery life on your iPhone
Thanks for using Apple Support Communities. Have a good one!
