Add a mailbox by opening Settings and connecting a new email account
A new mailbox in iPhone means adding another email account to the Mail app. When you add an account, iPhone creates a separate inbox for that email address and groups all its messages together. You do this through Settings, not through the Mail app itself — this is the step most people miss.
The process takes about five minutes if you know your email password. If you use Gmail, Outlook, Yahoo, or most other common providers, iPhone will recognize the account type and fill in the technical details for you. If the account is through your workplace or a less common provider, you may need to ask your email administrator for the server settings, but most people will not need this.
Key Takeaways
- Open Settings, tap Mail, then Accounts, then Add Account to start adding a new mailbox.
- Choose your email provider from the list (Gmail, Outlook, Yahoo, iCloud, or Other) so iPhone can configure the connection automatically.
- Enter your full email address and password, then let iPhone verify the account before you use it.
- Once added, the new mailbox appears in your Mail app inbox list and receives messages in real time.
- You can add up to ten email accounts to one iPhone, though each one uses a small amount of battery and storage.
Open Settings and navigate to Mail accounts
Start by opening the Settings app on your home screen. Scroll down until you see Mail — it has an envelope icon. Tap Mail to open its settings.
Inside Mail settings, tap Accounts. You will see a list of any email accounts already on your phone. At the bottom of this list is an Add Account button. Tap it to begin adding your new mailbox.
Select your email provider from the list
iPhone shows you a list of common email providers: iCloud, Google (Gmail), Yahoo, Outlook.com, and Other. If your email address ends in @gmail.com, tap Google. If it ends in @yahoo.com, tap Yahoo. If it ends in @outlook.com or @hotmail.com, tap Outlook.com. If it ends in @icloud.com or @me.com, tap iCloud.
If your email is through your workplace, your school, or a provider not on this list, tap Other. This does not mean something is wrong — it just means iPhone will ask you for more information. Most workplace email systems use standard settings that iPhone can find automatically once you enter your address and password.
Enter your email address and password
Type your full email address in the first field. Make sure you type it exactly as it appears — spaces, dots, and hyphens all matter. Then tap Next.
In the password field, enter the password you use to log into that email account. This is not your iPhone password or your Apple ID password — it is the password for the specific email address you are adding. If you are not sure what it is, you can reset it through your email provider's website before you come back to this step.
Tap Next again. iPhone will now contact your email provider's servers and verify that the address and password are correct. This takes about thirty seconds. If the password is wrong, iPhone will tell you and let you try again.
Choose which data to sync to your phone
After verification, iPhone asks what you want to sync from this account. You will see toggles for Mail, Contacts, Calendars, Notes, and Reminders. Most people leave Mail turned on and turn off the others unless they specifically want those synced too.
If you turn on Contacts, iPhone will read all the email addresses from this account's contact list. If you turn on Calendars, it will read any calendars associated with the account. You can change these settings later, so do not worry about getting it perfect right now. Tap Save when you are done.
Find your new mailbox in the Mail app
Open the Mail app from your home screen. Tap the Mailboxes button at the bottom left (it looks like a folder). You will now see all your email accounts listed, including the new one you just added. Each account has its own inbox, sent folder, and other standard folders.
The new mailbox will start receiving messages when ready. If you have a lot of old messages in that account, iPhone may take a few minutes to read them all, especially if you are on a slower internet connection. You can use Mail while this happens — it will not slow you down.
Manage multiple mailboxes and check which account you are using
When you have more than one mailbox, the Mail app shows you an Inbox that combines messages from all accounts by default. If you want to see messages from just one account, tap that account's name in the Mailboxes list. To go back to the combined view, tap All Inboxes at the top.
When you write a new message, check which account it will send from — you will see the account name just above the To field. If you want to send from a different account, tap the account name to change it. This is important if you have a work email and a personal email, because sending from the wrong one can cause confusion.
Frequently Asked Questions
What if iPhone says the password is wrong but I know it is correct?
Some email providers require you to create a separate app password for Mail on iPhone, different from your regular login password. Gmail and Outlook both do this if you have two-factor authentication turned on. Check your email provider's security settings or help page for "app password" or "app-specific password" and use that instead.
Can I add the same email address twice to see messages in two different ways?
No — iPhone will not let you add the same email address a second time. If you want to organize messages from one account differently, use the Mail app's VIP list or create custom folders and rules instead.
How many email accounts can I add to one iPhone?
You can add up to ten email accounts. Each one uses a small amount of battery power and storage space because iPhone checks them for new messages throughout the day. If your phone is running slowly or the battery drains fast, removing accounts you do not use regularly can help.
Will adding a new mailbox delete messages from my other accounts?
No — adding a new account does not affect your existing accounts or their messages. Each mailbox is completely separate.
What does "Other" mean when choosing an email provider?
Other means your email is not from one of the major providers iPhone recognizes automatically. This includes workplace email, school email, and smaller email services. Choose Other and enter your email address — iPhone will usually figure out the settings on its own. If it cannot, you will need to contact your email administrator for the server information.
