Troubleshooting an iPhone that won’t send emails in iOS 13

Before you start ruling out software-related factors that caused your iPhone to stop sending emails in iOS 13, check your cellular or Wi-Fi signal. Poor or weak signal on the device can be the main reason why email sending would fail. This is usually the case if your phone is experiencing signal issues on either Wi-Fi or cellular data network. Also ensure that the Airplane Mode switch isn’t turned on. When Airplane mode is turned on, all wireless connections are disabled so you won’t be able to use Internet services including email. If you see the Airplane symbol on your phone’s status bar, then that indicates Airplane mode is enabled and so you’ll need to disable it again through your iPhone settings. 

First solution: Quit and restart the Mail app.

Even pre-installed apps like Mail could end up going rogue after a major system transition. If this is the reason why you cannot send emails on your iPhone 7 after updating to iOS 13, restarting Mail is likely what you needed. Here’s what you should do then:

  1. Double-press the Home button to pull up the Apps Switcher or Multitasking screen. This contains the previews/cards of all app you’ve recently used and left open on your phone.
  2. Tap and drag the Mail app preview to the top-corner of the screen.

The app will then disappear and be closed. If you see any other apps that are left open and running in the background, follow the same steps to close them all out. Doing so will help prevent any of these apps to cause conflicts to the Mail app the next time you load it up.

Once you’re done clearing all other background apps, launch the Mail app again then try to resend the email you failed to send earlier from your Outbox with these steps:

  1. Tap Mailboxes in the upper-left corner then select Outbox. Emails that weren’t sent successfully are stored in the Outbox folder. 
  2. Tap to select the email in the Outbox.
  3. Verify and ensure that the recipient’s email details are correct and valid. Make some changes, if needed.
  4. Then tap Send to resend the email.

If the email still failed to send, clear out other software-related factors using the next method(s).

Second solution: Soft reset/reboot your iPhone.

A soft reset can fix various types of problems including those inflicted by minor iOS bugs. Thus, if you haven’t already, follow these steps to soft reset your iPhone 7:

  1. Press and hold down the Side (Power) button for a few seconds until the Slide To Power Off appears.
  2. Drag the slider to the right to power off your device completely.
  3. After 30 seconds, press and hold down the Side (Power) button again until the Apple logo appears.

After rebooting, launch the Mail app on your iPhone and see if the problem is gone. Otherwise, troubleshoot further.

Third solution: Check and manage your Mail settings.

While iOS automatically uses the correct settings for your email account during the setup, any of these settings could end up being flawed, especially if the new update imposes automatic overrides. To make sure that your email account settings are correct, check and see if the settings in the Mail app are the same as the ones used for your email account. Here’s how:

  1. From the Home screen, tap Settings.
  2. Select Accounts & Passwords.
  3. Tap on your email account.
  4. Tap your email address next to Account. Doing so will show up the account information such as the incoming mail server and outgoing mail server.

You can use the Mail Settings Lookup tool if you feel the need to check the recommended settings for your email account. If they don’t match, then you need to make necessary changes to correct them.

Fourth solution: Check and manage cellular and Wi-Fi settings on your phone, if applicable.

As mentioned earlier, network problems can also be the underlying cause of the problem. It is possible that your device is experiencing random problems that caused your Wi-Fi or cellular connection to become unstable. If this happens, emails will likely fail to send. To make sure this isn’t causing the problem, check and manage your network settings.

  1. To check and see if Wi-Fi is enabled, go to Settings-> Wi-Fi menu then make sure that the switch next to it is turned on. If it’s currently turned on, toggle to turn Wi-Fi off for a few seconds and then turn it back on again.
  2. If you’re on cellular data, go to Settings-> Cellular menu then make sure that the Cellular Data switch is turned on. Again, you can toggle the switch off and on shortly to restart and refresh your phone’s mobile data connections.

Once you’re done making necessary changes to your internet settings and ensure that your iPhone is connected to the Internet, launch the Mail app again and retry sending a sample email to your own email address.

Fifth solution: Delete your email account then add it back.

Your email account might have been corrupted after the recent operating system transition and is therefore no longer working unless you set it up again. Hence, consider email account deletion as your next option. The following steps will walk you through the entire process of removing your email account from your iPhone 7 and set it up again:

  1. From your Home screen, tap Settings.
  2. Select Accounts & Passwords.
  3. Tap to select the email account that you want to remove.
  4. Then tap the option to Delete Account.

Follow the rest of the onscreen prompts to complete the email account deletion process. After deleting the email, restart your iPhone then start adding your account again.

You can automatically set up your email account or add it manually. The latter option is recommended only if you know the email settings for your account. If you’re not sure of what information to enter, contact your email service provider or use the lookup tool found on the Apple Support website.

Removing your email account from your device doesn’t delete your mails. For as long as they’re all saved in webmail, you can always view them from any device anytime.

Sixth solution: Reset network settings to fix your iPhone that won’t send emails in iOS 13.

To eliminate incorrect network settings including flawed overrides from the recent software update, try to reset your phone’s network settings. Doing so deletes all your current network configurations and then restores the original network values without affecting the internal data saved on the iPhone storage. Just follow these steps whenever you’re ready:

  1. From your Home screen, tap Settings.
  2. Select General.
  3. Scroll down to and tap on Reset.
  4. Select the option to Reset network settings.
  5. Enter your device passcode when asked to proceed.
  6. Tap the option to confirm that you’d want to reset network settings on your device.


After the reset, you will be disconnected from the internet since Wi-Fi and cellular data will be disabled. To resume internet connection, re-enable Wi-Fi or cellular data on your phone.

The problem you’re dealing with could be due to some major system flaws the require some gritty solutions. This is when resorting to a full system wipe out and reset can be considered an option. If you wish to troubleshoot further, you can proceed with a factory reset, recovery mode restore, and DFU mode restore. You can start with a factory reset first, to erase everything from your device and then restores the factory default settings. This will allow you to set up everything as new.

  4. Tap on Reset.
  5. Tap the option to Erase all content and settings.
  6. If prompted, enter your device passcode to proceed.
  7. Confirm that you want to reset your iPhone and restore its factory defaults.


In the case where your iPhone is experiencing wireless connectivity issues and its internet connection is not stable, performing a factory reset through iTunes would be necessary. You will need to secure a computer that’s connected to the Internet and has the latest version of iTunes software in it. Once everything is set, follow these steps to start wiping and restoring your iPhone 7 to its factory defaults:

  1. Open iTunes on your computer, if you haven’t already.
  2. Connect your iPhone to the computer with the USB cable or Lightning cable that came with it.
  3. Wait for iTunes to recognize your device and when it does, you should see your iPhone’s icon in iTunes.
  4. Click to select your iPhone when it appears in iTunes.
  5. Then navigate to the Summary section.
  6. Click on the Restore [iPhone] button.
  7. If prompted, click on the Restore button again to confirm. iTunes will then start to wipe your iPhone and then attempt to install the latest firmware version available for your device.

Just follow the rest of the onscreen commands to complete the entire factory reset. Once everything is finished, set up your iPhone using the start-up wizard. This will allow you to set up all necessary features using automatic (correct) settings. After reconnecting to Wi-Fi, launch the Mail app and set up your email account. Be sure to input the correct email account details. As soon as you’re finished setting up your email, create a sample email to send and receive from/to your email address.

If you wish to skip to restoring iOS via recovery mode or DFU mode, you need to get a computer that’s connected to the Internet and has the latest iTunes version. Then you can refer to the step-by-step guide on how to restore an iPhone 7 in recovery mode or DFU mode on this site’s tutorials section.

Still having trouble with your iPhone 7 that won’t send emails in iOS 13?

If your phone still won’t send emails through the Mail app and it asks you to enter a password for your email account, then the problem is more likely due to an incorrect password entered.  In this case, all you have to do is to type in the correct password that’s associated with that email account. You can try logging into that email via webmail to check if you can sign into your account using the same email address and password. If you’re still getting a username or password error, contact your email service provider for further assistance. You may need to reset the password to access the email account again.
