Your iPhone is likely set up to lock automatically after a few minutes of inactivity. This serves the purpose of both preserving your battery life by turning off the screen, while also locking the screen so that it cannot be accidentally interacted with.
But if you are not using alerts on your lock screen, then you will need to periodically unlock your device to check for new email messages or text messages. Fortunately you can set up your iPhone so that you receive alerts on your lock screen when you receive email messages in your Yahoo account, which will let you know about new emails without requiring you to unlock the device.
Yahoo Email Alerts on the iPhone Lock Screen
This tutorial is specifically for showing Yahoo alerts on your lock screen, but you can follow the same steps to show email alerts from other accounts as well.
Note that there are two types of notifications on the iPhone. You can use alerts, or you can use banners. Banners are displayed at the top of the screen, and go away after a few seconds. Alerts are shown at the center of the screen, and need to be manually dismissed.
Step 1: Touch the Settings icon.

Step 2: Scroll down and select the Notification Center.

Step 3: Scroll down and select the Mail option.

Step 4: Select the Yahoo option.

Step 5: Select the Alerts option at the top of the screen.

Step 6: Scroll down and touch the button to the right of Show on Lock Screen. The button will have green shading around it when the feature is turned on.
