This article describes what to do if you are unable to send or receive email messages in the Mail app on your iOS device.
There are several conditions to consider.
- Backups of data from iOS devices in iCloud and iTunes contain your email settings, but not the messages themselves. If you delete or change your email account settings, previously downloaded messages may be deleted from your iOS device.
- Make sure your device is connected to the Internet. To check your cellular or Wi-Fi network connection, launch the Safari browser and open any web page.
- Ask your email service provider if there has been a temporary malfunction on his web page.
Checking for Outbox Email Messages
A notification that an e-mail message has not been sent means that this message is placed in the Outbox folder. Check your outbox and try sending the email again.
- In the "Mail" program, click "Mailboxes" in the upper left corner.
- Select Outbox. If the Outbox folder is missing, then an email message has been sent.
- Click the email in the Outbox folder. Make sure the recipient’s email address is correct.
- Click Submit.
Verify Email Address and Password
If the Mail program asks for a password for your email account, make sure it is entered correctly. To verify your email address and password, log in to the website of your email service provider.
If you still report that the username or password is incorrectly entered, contact your email service provider or system administrator.

Check your email and notification download settings in iOS
By default, the settings in the Data Download section are based on email settings. If the Push option is not available, the Select option will be enabled by default. It depends on how your device will receive email. To change these settings, follow these steps:
- Go to the "Settings" section.
- Click Passwords and Accounts.
- Click "Download Data."
- Select an option (for example, “Automatic” or “Manual”) or set a schedule for loading data in the Mail program.
In iOS 11 and later, the default setting is Automatic. Your device will download data in the background only during charging or when connected to a Wi-Fi network.
Check the correct notification settings for the Mail program.
- Go to the "Settings" > "Notifications."
- Click Mail.
- Click your email account.
- Configure Alerts, Sounds, and Stickers.
Checking Mail Settings
On an iOS device, for many email providers, the correct account settings are automatically selected.
To check if this is the case, compare the settings in Mail and your email account.
- Select "Settings" > “Passwords and accounts” and then your email account.
- Click your email address next to the “Account” line to view account information, such as the addresses of incoming and outgoing mail servers.
- Review the recommended settings for your email account using the Search for Mail preferences tool and make sure they match yours. If your email account settings do not appear, contact your email service provider or system administrator.
If you are using a POP3 email account, you can only check mail on one device. Close other email programs and end sessions on open mail websites in a browser. To check if your email account uses the POP3 protocol, go to the Settings menu > “Passwords and accounts”, select your account and find the “POP Account Information” label. You can also find out the recommended email settings for your POP3 account using the Find Mail Preferences tool.
If additional assistance is required
Contact your email service provider. You can also delete your email account and set it up again.
