Q: My email is foll of "no sender" "no subject". I can't delete any of them

Hi justbjay!

I would recommend that you follow the steps for troubleshooting an issue with sending and receiving mail in iOS for this particular issue. Those steps can be found right here:

If you are unable to send or receive email, try the following steps:

1. Restart the iOS device.
2. Tap Safari and attempt to load a webpage to ensure that the device has Internet access. If you're unable to load a webpage, try the Wi-Fi assistant.
3. Try an alternative Internet connection.
   • If your email is provided by your Internet provider, try connecting from the home network.
   • If your iOS device has an active cellular data plan, try to disable Wi-Fi:  Tap Settings > Wi-Fi and turn off Wi-Fi.
   • If not, try a different Wi-Fi network.
4. Log in to your email provider's website to ensure that the account is active and the password is correct.
5. Delete the account from Settings > Mail, Contacts, Calendars and then add the email account again on the iOS device.
