Why i can't receive mails in my icloud account?

Hi Annedelarosa29,

Since you're unable to receive emails on your device, we recommend that you try the steps here: If you can't receive email on your iPhone, iPad, or iPod touch - Apple Support

To perform the steps in the article we suggested above, click and open the link, read the subheadings below, and try each step.

1) Check your email address and password

2) Check Mail Fetch and Notification settings

3) Contact your email provider or system administrator

4) Remove your email account and set it up again

The reason why we are recommending the steps above is because they will show you what to do if you can’t receive email in the Mail app on your iPhone, iPad, or iPod touch.

In the event that you're using a Mac, then give the steps here a try: If you can’t receive emails in Mail on Mac - Apple Support

Please let us know the outcome after giving the above steps a try.

Thanks for using the Apple Support Communities.

Cheers!
