Where to find and change your email address
On iPhone, the steps to change your email address depend on which email service you use and whether you're changing the address itself or just updating how it appears in the Mail app. If you use iCloud Mail, Gmail, Outlook, or another service, the process differs slightly — but all of them start in the Settings app, not in Mail itself.
For most email accounts, you'll go to Settings > Mail > Accounts, tap the account you want to change, and then look for options to edit the email address or account details. The exact menu varies by provider, but this is where iPhone stores all your email configuration.
If you're trying to change your actual email address with a provider (not just how it displays on your phone), you'll need to do that through the provider's website or app first — iPhone can only change how the account is set up on your device, not the address itself at the source.
Key Takeaways
- Changing how your email address appears on iPhone happens in Settings > Mail > Accounts, not in the Mail app itself.
- If you want to change your actual email address with a provider like Gmail or Outlook, you must do that on their website or app before updating iPhone.
- For iCloud Mail, you can add or remove email addresses directly in Settings > [Your Name] > iCloud, without removing the account.
- Removing and re-adding an email account on iPhone will sync your past messages again once you sign back in with the new address.
Changing the display name or "from" address
If you want to change what name appears when you send an email — for example, changing from "John Smith" to "J. Smith" — that's the easiest change to make. Open Settings, tap Mail, then Accounts, and select the account you want to edit. Tap your name at the top of the account details, and you'll see a field for "Name" that you can edit directly.
This change only affects how your name displays to people who receive your emails. It doesn't change your actual email address, and it only changes the setting on this iPhone — if you use the same email account on another device, you'll need to make the same change there too.
Removing an account and adding it again with a different address
If you've changed your email address with your provider and need to update it on your iPhone, the most straightforward approach is to remove the old account and add the new one. Go to Settings > Mail > Accounts, tap the account you want to remove, scroll to the bottom, and tap "Delete Account." Choose whether to keep or delete the messages stored on your phone.
After you delete it, tap "Add Account" at the bottom of the Accounts list, select your email provider, and enter your new email address and password. iPhone will re-download your past messages and sync them with the new account, so you won't lose your email history.
This process takes a few minutes and requires you to know your new password. If you've forgotten it, you'll need to reset it through your email provider's website before you can add the account to iPhone.
Adding multiple email addresses to the same account
If your email provider lets you use multiple addresses that all go to the same inbox — a feature Gmail and Outlook both offer — you can add those addresses to iPhone without creating separate accounts. In Settings > Mail > Accounts, tap the account, then look for an option like "Email" or "Alternate Email Addresses" (the label varies by provider).
Tap the field and add the additional address. When you compose a new email, you'll then see a dropdown menu that lets you choose which address to send from. This is useful if you have a work email and a personal email that both deliver to the same inbox, or if you use email aliases.
Updating an iCloud email address
iCloud Mail works differently from other email services because your iCloud account is tied to your Apple ID. If you want to add a new iCloud email address, go to Settings > [Your Name] > iCloud, tap "Mail," and then tap "Manage Account." From there, you can add an iCloud alias — a secondary email address that uses the @icloud.com domain.
You cannot change your primary iCloud email address on iPhone; that requires going to appleid.apple.com on a computer or using the Apple ID app. If you need to change your primary iCloud address, you'll have to do that through Apple's website, and then the change will sync to your iPhone automatically.
What happens to your messages when you change accounts
When you remove an email account from iPhone, the app asks whether you want to keep or delete the messages. If you tap "Keep on My iPhone," your past emails stay in the Mail app but stop syncing with the server — they become a local copy only. If you tap "Delete," they're removed from your phone, though they remain on your email provider's server.
When you add the account back with the new address, iPhone will re-download all your past messages from the server, so you don't lose anything. This re-download can take several minutes if you have thousands of emails, and it requires an internet connection.
Troubleshooting when the change doesn't work
If you've changed your email address with your provider but iPhone won't accept it, the most common reason is that you're using an old password. Email providers often require you to generate a new app-specific password when you change your address, especially for Gmail and Outlook. Check your email provider's security settings and generate a new password if needed.
If you're still having trouble, try removing the account completely, restarting your iPhone, and then adding it again. Sometimes the Mail app gets stuck trying to sync with old server settings, and a fresh start clears it. Make sure you're connected to Wi-Fi or a strong cellular signal during this process.
Frequently Asked Questions
Can I change my email address without removing the account from iPhone?
Not if you've changed the address with your provider. You can only change the display name or add alternate addresses that your provider supports. To use a completely new email address, you'll need to remove the old account and add the new one.
Will I lose my emails if I remove the account?
No, as long as you choose "Keep on My iPhone" when you delete the account. Your emails stay on your phone and on your provider's server. When you add the account back, they'll sync again.
Why does iPhone keep asking for my password after I change my email address?
Your provider may require a new app-specific password for security reasons, especially if you changed your main account password. Go to your email provider's website, generate a new app password, and use that instead of your regular password when adding the account to iPhone.
Can I send emails from multiple addresses on the same iPhone?
Yes, if your provider supports it. You can add multiple accounts to Mail, or add alternate addresses to a single account. When you compose an email, you'll see a dropdown to choose which address to send from.
