Hello cartydavis,

Thanks for using Apple Support Communities.

To troubleshoot this issue where you're unable to receive iCloud Mail on your iPhone, please follow through the steps outlined below.

If you need help sending or receiving mail on your iPhone, iPad, or iPod touch

1. Make sure that you're connected to the Internet. Try to open apple.com in Safari on your iPhone, iPad, or iPod touch.
2. Go to iCloud.com on a Mac or PC to see if you can receive email for your iCloud account.
3. Tap Settings > iCloud and turn on Mail on your iPhone, iPad, or iPod touch.
4. Tap Settings > Mail, Contacts, and Calendars > Fetch New Data and turn on Push. Then send an email to your account to see if Push is working.
5. Tap Settings > Mail, Contacts, and Calendars > Fetch New Data. Then Tap your iCloud account and turn on Push. If you have multiple iCloud Mail accounts, you can use Push with one account at a time. Make sure that Push is turned on for your primary iCloud Mail account.
6. Turn your device off and back on.

If you still can't send or receive mail, turn off each of the settings in steps 3, 4, and 5 above, then turn them back on.
