Notifications on Apple Mail app extremely late

I’m happy to report that this behavior seems to be fixed with iOS 15. Ever since updating (which has admittedly been only two days so far) e-mails arrive absolutely immediately. Even before Mail on macOS notifies me of them, which it always did before my iPhone previously. I hope it stays this way.

Thanks for your response.

First, if you want your incoming email to be sent to your phone whenever possible, ensure that "Push" is selected (green).

Push is selected for my iCloud account.

Then check the Fetch settings for how often the phone will check for new messages. Specifically:

"Go to Settings > Mail, then tap Accounts.

Tap Fetch New Data.

Choose a setting — like Automatically or Manually — or choose a schedule for how often the Mail app fetches data."

I have tried basically all of the Fetch settings, none of them make a difference (which they shouldn’t anyway because iCloud is set to Push). Currently it is set to fetch hourly.

The problem isn’t that I don’t receive notifications at all, it’s that they can be extremely late (up to multiple hours). For example, in relation to your response I received an email at 4:17 PM my time, but the notification on my iPhone didn’t arrive until 4:55 PM. This delay can easily be up to 8 hours.
