Here are the top 5 solutions for not receiving emails on iPhone:
1. **Check your internet connection.** Make sure that your iPhone has a stable internet connection. If you are connected to Wi-Fi, try restarting your router. If you are using cellular data, try turning it off and on again.
2. **Check your email settings.** Make sure that your email settings are correct. To do this, go to Settings > Mail > Accounts. Then, select the account that you are having problems with. Make sure that the Fetch New Data setting is set to Automatic or Manually. If it is set to Manually, you will need to refresh the app to receive new emails.

Then, slide the button to the right. To turn your iPhone back on, press and hold the power button until you see the Apple logo.
4. **Update your iOS software.** Make sure that your iPhone is running the latest version of iOS software. To check for updates, go to Settings > General > Software Update. If an update is available, download and install it.
5. **Delete and re-add your email account.** If you have tried all of the above steps and you are still not receiving emails, you can try deleting and re-adding your email account. To do this, go to Settings > Mail > Accounts. Then, select the account that you are having problems with. Tap on Delete Account. Then, tap on Add Account and follow the instructions to add your account again.
If you are still having problems receiving emails after trying all of the above steps, you may need to contact your email provider for assistance.
