I don’t get email notifications on my iPhone until I open app

Greetings Sicu55liana, 

Mail notifications on iOS can be a little tricky due to Push versus Fetch and manual settings. 

Let’s go over it. Don’t be dissuaded by this article title, it has the steps we’re looking for - If you can't receive email on your iPhone, iPad, or iPod touch Also, your iPhone itself is a great source for information about notifications for the Mail app. In Settings > Mail > Accounts > Fetch New Data it talks about the difference in notification and retrieval types and what specifications have to be met. 

Check Mail Fetch and Notification settings

By default, Fetch New Data settings are based on what's provided by your email service. If Push isn't available as a setting, your account will default to Fetch. These settings affect how your device receives email. To adjust these settings:

1. Go to Settings > Mail, then tap Accounts.

2. Tap Fetch New Data.

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

With iOS 11 and later, and iPadOS, Automatically is set by default. Your device will fetch new data in the background only when your device is charging and connected to Wi-Fi.

Make sure that your Notification settings are correct for the Mail app:

1. Go to Settings, then tap Notifications.

2. Tap Mail, then tap an email account.

3. Adjust your Alerts, Sounds, and Badges.

Thanks.

apple provided fetch options in the mail app that are inferior to push (instantaneous, always up to date) for accounts that are NOT icloud.

i am often using google’s gmail app because my email comes instantaneously, vs waiting for apple mail to notify me of an email based on its fetch settings.

the apple mail app for ios is cool, easy to use and i like the filter option to show me only email from ‘today’.

but i dont like the restriction that fetch has, that is apple telling its users ‘switch to icloud mail’, same manner as how the CEO recently told a reporter to go get his mom an iphone.

thats not cool
