How to fix email sending error on iPhone XR Gmail app

An email sending error on your Apple iPhone XR could be a sign of a problem with the email app you’re using or it could be due to an issue with your internet. It’s a very annoying problem but not necessarily difficult to fix and that’s what we’re going to do in this post.

Gmail is one of the reliable email platforms used by many iPhone owners. While Apple’s very own Mail app offers the same email experience, the Gmail app embeds a number of advanced cool features that aren’t found on the stock Mail app. But despite the fact that Gmail is maintained by the Internet giant, there are still instances when the app encounters some errors and so it would fail to work as intended.

Tackled in this post is a pertinent issue on the iPhone XR Gmail app. Read on to learn what to do if you’re getting an email sending error when using Gmail app on your iPhone XR. Before anything else, if you are looking for a solution to a different problem, then drop in on our iPhone XR Help Guides page for we have already solved some of the most common problems with this device. Try to find issues that are similar with yours and feel free to use our workarounds and solutions.

Solution #1: Check your Mail Outbox and then resend the unsent email.

If you are unable to send an email on your Gmail app, try resending the email from the Outbox before performing complex troubleshooting on your phone. Unsent emails are typically routed to the Outbox folder, so you better open that folder first. This could be just an isolated problem with Gmail and therefore can be fixed easily by resending the message from the Outbox folder. Here’s how to resend the email from your Outbox:

From the Home screen, select the Mail app.
Tap Mailboxes located in the upper-left corner.
Under Mailboxes, scroll to and select Outbox to check for unsent messages.
Double-check the recipient’s email address and once it’s verified correct, tap Send.

If the Outbox no longer shows messages, then the message was already sent successfully. However, if you’re still getting an email sending error, then you may troubleshoot your phone further.

Solution #2: Close the Gmail app and restart (soft reset) your iPhone XR.

If you haven’t closed the Gmail app properly and it has been left running in the background for a long period of time, then it’s possible that the app has crashed and gone rogue. To fix it, simply clear out or end the Gmail app and other apps that were left suspended on your iPhone. Here’s how you do it:

On your Home screen, swipe up and then pause.
Swipe either left or right to navigate through the apps preview and locate Gmail.
Then swipe up on the Gmail app review to close it. If it shows multiple apps on the screen, close the remaining apps as well.

Closing all the running apps will prevent any of them from conflicting Gmail app functions. After closing the apps, restart your phone to eliminate minor software errors that may have also caused the Gmail app sending function to fail. This reset does not affect any saved files in your phone memory so there is no need to create backups.

Follow the steps below to soft reset your iPhone XR:

Press and hold the Side/Power button and either Volume buttons simultaneously for a few seconds.
When the Slide to Power off command appears, release the buttons.
Then drag the power off slider to the right.
After 30 seconds, press and hold the Side/Power button again until the Apple logo appears.

Once your iPhone is already back on, check your Gmail app and see if you are already able to send an email. If there’s still an email sending error, move on to the next solution.

Solution #3: Update the Gmail app on your iPhone XR.

If the Gmail app was just working fine and then suddenly sending email fails, it is possible that the app requires some update. At this point, you can check for new version of the app from the App Store. Just like the iOS update, developers for third-party apps also roll-out update to offer new features of the apps so as to provide patch codes to fix complex software errors and malwares that caused Gmail app to stop sending emails. To check for available app updates, refer to these steps:

From the Home screen, tap App Store.
Scroll down to and tap the Updates tab to check the list of apps with pending updates.
Scroll through the list and find Gmail.
If a pending update is available for Gmail, tap the Update button next to Gmail app.
If multiple updates are available, tap the Update All button on the upper-right corner to simultaneously update all the apps.

To apply the recent update and refresh the operating system of your iPhone, reboot your phone after the update. Once it is already back on, launch the Gmail app and try sending an email to see if it will be successfully.

Solution #4: Delete and re-install the Gmail app from your iPhone XR.

If you’re still getting the same email sending error message, it’s possible that the app has been corrupted and is no longer working. In this case, uninstalling the corrupted Gmail app and installing the latest version of the app will likely solve the problem. So this is what you should do next:

From the Home screen, tap and hold on an app icon until the icons start to jiggle.

Read the notification prompts and select Delete to confirm the deletion of the Gmail app.
After deleting the app, restart (soft reset) your iPhone XR.
Then launch the App Store.
Search for and select the Gmail app from the search results.
Tap either the Cloud icon or the Get button to download and reinstall the Gmail app on your iPhone.

Once the Gmail app has been completely reinstalled, launch the app and see if the problem has been fixed.

Solution #5: Remove and re-add the Gmail account from your iPhone XR.

Upon setting up your email account, the correct account settings are automatically registered on your device. However, it is possible that these settings have been overridden when changes on the phone settings had been made. To correct invalid or incorrect Gmail app settings, delete your Gmail account and then add it back. Here’s how it’s done:

From the Home screen, go to Settings.
Scroll down to and tap Accounts & Passwords.
Scroll through the Accounts section and then select the email account (Gmail account) that you want to delete.

The select Delete from My iPhone option.

Troubleshooting network issues that may have caused email sending error

Performing the above solutions usually solves the problem if in-app glitches are to blame. If your iPhone continues to encounter email sending errors, then you’ll have to troubleshoot further and this time, rule out network problems with these methods.

Reset network settings. If the reason of the email sending error on your device is due to invalid network configurations, then carrying out a network reset will likely fix the problem.

To do this, head over to Settings-> General-> Reset menu and then select the option to Reset network settings.

This process will delete all networks saved on your phone which means that you will need to set up Wi-Fi network to reconnect your iPhone later.

Check and modify your Mail settings. Although correct account settings will be automatically registered on your phone when setting up the email, it is still recommended to check the mail settings to ensure that the valid incoming and outgoing mail servers were added.

To check, head over to Settings-> Password & Accounts-> tap on your email account-> then tap your email address next to Account-> check incoming and outgoing mail servers.

You can check the Lookup tool available on Apple website to check the correct settings on your account.

If none of that works, then you should already contact your email service provider or system administrator to obtain the correct email server information and/or seek for further assistance in fixing the error.
