The two places you need to change your email

Your iPhone stores email in two separate places, and changing it means updating both. The first is your Apple ID — the account that lets you read apps, use iCloud, and back up your phone. The second is the email account itself inside the Mail app, which is where your actual messages live. You can change one without changing the other, but most people need to do both.

If you only change your Apple ID email, your Mail app will keep using the old address. If you only change the Mail account, your Apple ID will still be tied to the old email. This guide walks you through both, starting with whichever one matters most to you right now.

Key Takeaways

  • Your Apple ID email and your Mail app email are separate — changing one does not change the other.
  • To change your Apple ID, go to Settings > [Your Name] > Password and Security > Change Email, and Apple will send a confirmation link to your current email first.
  • To change a Mail account, go to Settings > Mail > Accounts, select the account, tap Account, then Email, and enter your new address.
  • After changing your Apple ID email, you will need to sign out and sign back in on your iPhone for the change to take effect.
  • If you are changing to a brand-new email address you have never used before, create that address first on a computer or another device.

Changing your Apple ID email address

Your Apple ID is the account you use to sign into your iPhone itself. To change the email attached to it, open Settings on your home screen and tap the box at the very top with your name and photo. Then tap Password and Security. You will see a line that says "Email" — tap Change Email next to it.

Apple will ask you to confirm your current password. Type it in and tap Next. Now you will see a screen asking for your new email address. Type the address you want to use instead. This can be a brand-new address you just created, or an address you already own. Tap Change.

Apple will send a confirmation email to your current email address — the one you are changing away from. Go check that inbox (on your iPhone or on a computer) and open the email from Apple. It will have a link inside. Tap or click that link to confirm the change. Once you do, your Apple ID is now tied to the new email address.

After you confirm, sign out of your iPhone and sign back in. Go to Settings > [Your Name] > tap Sign Out at the bottom. When you sign back in, use your new Apple ID email address and your password. This makes sure your phone fully recognizes the change.

Changing the email address in your Mail app

The Mail app on your iPhone can hold multiple email accounts — Gmail, Outlook, Yahoo, or any other service. If you want to change one of them, open Settings and scroll down to find Mail. Tap it, then tap Accounts. You will see a list of all the email accounts currently set up on your phone.

Tap the account you want to change. On the next screen, tap Account near the top. Now tap the line that shows your email address. Delete the old address and type in the new one. Tap Save in the top right corner.

Your iPhone will try to connect to your email service using the new address. If the address is correct and you have the right password saved, it will work right away. If you see an error message, it usually means either the address is wrong or your email service does not recognize it yet. Double-check the spelling and try again.

What to do if you created a brand-new email address

If you are switching to an email address you just created — say, a new Gmail account — create that account first on a computer or tablet before you try to add it to your iPhone. This gives the email service time to set up the account fully. Then come back to your iPhone and follow the steps above to add it to Mail or change your Apple ID.

If you try to add a brand-new address to your iPhone before it is fully set up on the email service's website, you will get a connection error. The account exists, but the email service has not finished initializing it yet. Waiting a few minutes and trying again usually fixes this.

Why your old email might still appear after you change it

After you change your email address, you might still see the old one pop up in certain places on your iPhone. This happens because your phone caches — stores a copy of — old information. Restarting your iPhone clears this cache and forces it to reload everything fresh. Hold down the power button and volume button together until you see the power-off slider, then slide it. Wait 30 seconds, then press the power button again to turn it back on.

If you changed your Apple ID email, you might also see the old address in Settings for a few hours while Apple's servers update everywhere. This is normal and will disappear on its own. If it does not disappear after a full day, sign out and sign back in again as described above.

Changing email on your other Apple devices

If you use an iPad, Mac, or Apple Watch, they are all connected to the same Apple ID. When you change your Apple ID email on your iPhone, those devices will ask you to sign in again the next time you use them. Use your new email address and your password. This keeps everything in sync.

Mail accounts are separate on each device. If you changed an email account in Mail on your iPhone, it only changes on your iPhone. If you want the same change on your iPad or Mac, you will need to repeat the steps on those devices too.

Frequently Asked Questions

Do I need to change my Apple ID email if I only want to change my Mail account?

No. Your Apple ID and your Mail accounts are completely separate. You can change one without touching the other. Most people only need to change their Mail account if they are switching email providers. Only change your Apple ID email if you want a different address for signing into your iPhone and downloading apps.

What happens to my old email account after I change it?

If you changed your Mail account, the old account stays active on your email service's servers — your iPhone just stops checking it. You can still access it on a computer or through the email service's website. If you changed your Apple ID email, the old address is no longer tied to your Apple account, but the email address itself still exists if you created it somewhere.

Can I use the same email address for both my Apple ID and my Mail account?

Yes, and many people do. Your Apple ID email and your Mail account email do not have to match, but they can. If you want them to be the same, change your Apple ID email first, then change your Mail account email to match it.

Why does my iPhone keep asking me to sign in after I changed my email?

When you change your Apple ID email, your iPhone needs to re-authenticate — confirm that you own the account. Sign out completely from Settings, then sign back in with your new email address and password. If it keeps asking after that, restart your iPhone by holding the power button and volume button together until the power-off slider appears.

Can I change my email address without a password?

No. To change your Apple ID email, you must enter your current password. To change a Mail account email, you usually need the password for that email account. If you do not remember your password, use the "Forgot Password" option on the email service's website to reset it first.
