If you can’t send emails on your iPhone or iPad
If you can’t send emails from the Mail app on your iPhone or iPad, there are a few things you can try.
Before you begin
There are a few things to bear in mind and check:
When you make an iOS or iPadOS backup in iCloud or iTunes, it backs up your email settings but not your emails. If you delete or change your email account settings, previously downloaded emails might be removed from your device.
Make sure your device is connected to the internet.
Check with your email service provider to find out if there’s a service outage.
Look for the Undo Send button in your Inbox or list of mailboxes. If Undo Send is available, the message has not been sent.
Find out what to do if you can’t access your iCloud Mail, or you can’t send and receive messages with your @icloud.com email address.
Check the Outbox for unsent email
If you get a message that says your email wasn’t sent, that email goes to your Outbox. Check your Outbox and try sending the email again by following these steps:
In Mail, go to your list of mailboxes.
Tap Outbox. If you can’t see an Outbox, your email was sent.
Tap an email in the Outbox. Make sure the recipient’s email address is correct.
Tap Send.
Check your email address and password
If Mail asks you to enter a password for your email account, make sure your password is correct. To check your email address and password, sign in to your email provider’s website.
If you’re still receiving a username or password error, contact your email provider or system administrator.
Contact your email provider or system administrator
Contact your email provider or check their status web page to see if there's a service outage.
Ask your email provider or system administrator if you have turned on any security features or restrictions, such as two-step verification, for your email account. You may need a special password or have to request authorisation from your email provider to send and receive emails on your device.
Check your email account settings with your email provider or system administrator to make sure they’re correct.
Remove your email account and set it up again
On your computer, sign in to your email provider’s website. Make sure all of your emails are there or make sure your emails have been saved somewhere other than on your iOS or iPadOS device.
On your device, go to Settings > Mail, then tap Accounts.
Tap the email account you want to remove.
Tap Delete Account.
