Where to find the default email setting

Your iPhone's default email account is the one that opens when you tap the Mail app icon on your home screen. To change it, go to Settings > Mail > Default Account. You'll see a list of every email account you've added to your phone. Tap the account you want to use as your default, and it becomes active immediately.

This setting applies only to the Mail app itself. If you use Gmail, Outlook, Yahoo Mail, or another email app downloaded from the App Store, each one has its own default account setting inside that app — changing your iPhone default won't affect them.

Key Takeaways

  • Your default email account is the one that opens when you launch the Mail app, and you can change it anytime in Settings > Mail > Default Account.
  • You must have at least two email accounts added to your iPhone before the Default Account option appears in Settings.
  • Changing your default account in Settings affects only Apple's Mail app, not third-party email apps like Gmail or Outlook.
  • When you send an email from Siri or another app that uses Mail, it will use your default account unless you manually choose a different one.

What you need before you can change the default

The Default Account option only shows up in Settings if you have two or more email accounts set up on your iPhone. If you see only one account in Mail, or if the Default Account option is grayed out, you need to add another email account first.

To add an account, go to Settings > Mail > Accounts > Add Account. Choose your email provider (iCloud, Google, Microsoft Exchange, Yahoo, AOL, or Other), then enter your email address and password. Once the second account is verified, the Default Account option becomes available.

How the default account affects sending email

When you compose a new email in the Mail app, the "From" field automatically shows your default account. You can change it for a single email by tapping the "From" line and selecting a different account, but it will revert to your default the next time you write a message.

If you use Siri to send an email by voice — for example, "Send an email to Mom" — Siri will use your default account. The same applies when you share content from other apps (like Photos or Safari) and choose to send it via Mail. To use a different account for these actions, you have to change your default first, send the message, then change it back.

Changing the default for iCloud Mail specifically

If you have an iCloud email address and want to make it your default, the process is the same: Settings > Mail > Default Account > tap your iCloud account. iCloud accounts are often set up automatically when you sign into your iPhone with your Apple ID, so you may already have one without realizing it.

Your iCloud email address ends in @icloud.com, @me.com, or @mac.com. If you're not sure which accounts you have, go to Settings > Mail > Accounts and look at the list. The account marked with a checkmark next to its name is currently your default.

Why you might want to change your default account

You might change your default if you use one email address for work and another for personal messages, and you want Mail to open to your work account. Or if you've set up a new email address and want to use it going forward, making it default saves you from having to manually select it every time you send a message.

Some people keep an old email account on their iPhone just to receive messages but never send from it. Making a different account your default prevents accidentally sending from the old address when you're in a hurry.

What happens to your other accounts

Changing your default account does not delete, disable, or hide your other accounts. They stay on your phone and continue to receive new messages. You can still read mail from any account by tapping the Mailboxes button at the bottom of the Mail app and selecting the account you want to view.

If you want to stop using an account entirely, go to Settings > Mail > Accounts, tap the account, then tap Delete Account. This removes it from Mail but does not affect the account itself — you can add it back anytime.

Frequently Asked Questions

Can I set different default accounts for different apps?

No. Your iPhone has one default email account across all apps that use Mail. However, third-party email apps like Gmail or Outlook have their own separate default settings inside those apps. You can set Gmail as your default in the Gmail app and a different account as your default in Apple Mail.

What if I don't see the Default Account option in Settings?

You need at least two email accounts on your iPhone for this option to appear. Add a second account in Settings > Mail > Accounts > Add Account, and the Default Account option will show up.

Does changing my default account affect email I've already received?

No. All your existing emails stay in their original accounts. Changing the default only affects new emails you send and which account opens when you launch Mail.

Can I change my default account from the Mail app itself?

No. The default account setting is only in the Settings app under Mail. You cannot change it directly from within the Mail app.
