iCloud email not receiving all emails

"iCloud email not receiving all emails: My iCloud email is not receiving all emails sent to me. It is receiving some, but not all. An email was sent to my husband and myself this evening and he received, but I did not. He then tried to forward the email to me and I was still unable to receive it. My storage is not full, the sender is not blocked, I’ve checked all the things. She did send it to the correct email, and since this mishap, I have received other emails."

Troubleshooting iCloud eMail:

A. Start with these Links:

1. If iCloud Mail isn't Working - Apple Support
2. If you can't Send or Receive Mail on your iPhone or iPad - Apple Support
3. If you can't Send or Receive Mail from the Mail App on your Mac - Apple Support

B. Use New Login Sessions:

Log out of iCloud on your iPhone, and then log back in. Perhaps it all needs to re-sync?
