Mail app, notifications

Hello tomas154,

This is normal behavior for mail accounts that do not support the Push functionality (iCloud Mail does). Many mail provider only support the Fetch functionality. You can check this by going to Settings > Mail > Accounts > Fetch New Data and selecting your provider. If your provider supports Push, select it. You'll then receive notifications right away.

Otherwise, for Fetch-only accounts, the Mail app on the iPhone will only pick up new messages when it's open (or when your iPhone is charging). You can change this behavior by going to Settings > Mail > Accounts > Fetch New Data and setting the "FETCH" parameters, for instance "Every 15 Minutes". Mail would then pick up new emails every 15 minutes and you would be notified.

Change alert styles

To add or change an alert style for a notification:

1. Go to Settings > Notifications.
2. Select an app under Notification Style. 
3. Choose a type of alert and banner style. 

You can also turn sounds and badges on or off.

Change group notification settings

You can use group notifications or keep them separate.

1. Go to Settings > Notifications.
2. Select an app and tap Notification Grouping.
3. Select one of these options:

• • Automatic: Notifications from each app will appear in groups based on app alerts.
  • By App: All notifications from each app will be grouped into single expandable alerts.
  • Off: Notifications appear in the order they’re received, without grouping.

From here you can also choose how to show notification previews for specific apps. For example, you can have notification previews show up all the time or never, even when your device is locked.
