What you can and cannot change in your email address
You cannot change the username part of your email address — the part before the @ symbol. Once you create an account with Gmail, Outlook, Yahoo, or another provider, that username is permanent. If you need a different email address entirely, you have to create a new account.
What you can change is your display name — the name that appears when you send emails to other people. This is the "From:" name they see in their inbox. Changing your display name takes two to five minutes and does not affect your actual email address or any of your account settings.
If you created your email account under a name you no longer use, or if you want your emails to show a different name than what's on your account, changing the display name solves that problem without losing access to your existing email, contacts, or files.
Key Takeaways
- Your email username (before the @) cannot be changed; you must create a new account if you need a different address.
- Your display name — what recipients see in the "From:" line — can be changed in your account settings in under five minutes.
- Gmail, Outlook, and Yahoo each have slightly different steps, but all store the display name setting in your account or profile section.
- After you change your display name, it takes a few minutes to show up on new emails you send.
- Changing your display name does not affect your password, recovery email, two-factor authentication, or any stored messages.
How to change your display name in Gmail
Open Gmail and click the gear icon in the top right corner. Select "See all settings." Click the "Accounts and Import" tab. Under "Send mail as," find the email address you want to change and click "edit info" next to it.
A box will open with a field labeled "Name." Delete the current name and type the new one you want to appear on your emails. Click "Save changes" at the bottom. Gmail will ask you to confirm your identity by entering your password. After you do, the change is complete.
The new display name will appear on emails you send starting when ready, though it may take a few minutes to show up consistently across all devices you use.
How to change your display name in Outlook or Hotmail
Sign in to your Outlook account and click your profile picture or initials in the top right corner. Select "View account" or "Manage your Microsoft account." Click "Your info" on the left side. Under your name at the top of the page, click "Edit name."
Type your new first and last name in the fields provided. Click "Save" when you are done. Outlook will refresh your account, and the new name will appear on emails you send within a few minutes.
If you have multiple email addresses linked to the same Outlook account, you may need to repeat this step for each address if you want different display names for each one. Check your "Send from" settings to confirm which address uses which name.
How to change your display name in Yahoo Mail
Log in to Yahoo Mail and click the account icon (your profile picture or initials) in the top right. Select "Account info." Click "Personal info" on the left side. Find the "Name" field and click the pencil icon next to it.
Type your new name in the field. Click "Save" when you are finished. Yahoo will update your account, and the new display name will show on outgoing emails within a few minutes.
Yahoo also allows you to set different display names for different email addresses if you have multiple accounts. Each address can have its own name in the "Send from" settings.
What happens after you change your display name
Your display name change does not affect your login credentials, password, or recovery email address. You still log in with your original email address and password. All your existing emails, contacts, calendar events, and files remain exactly as they were.
People who have your email address in their contacts will see the new display name the next time you send them an email. Old emails you sent before the change will still show your old name in their inboxes — the change only applies to new messages going forward.
If you use email forwarding, filters, or automatic replies, those continue to work without any changes. Your display name is purely cosmetic and does not touch any of your account's underlying settings or security features.
If you need a completely different email address
If changing your display name is not enough and you actually need a different email address, you will need to create a new account with the provider. Gmail, Outlook, and Yahoo all allow you to create multiple accounts for free.
Once you have a new email address, you can set it up to forward to your old address, or you can use both addresses separately. Many people keep their old email address active for accounts and subscriptions that are tied to it, then use a new address for fresh communications.
If you want to transfer important emails from your old address to your new one, most providers have an import or forwarding tool. Gmail's "Import mail & contacts" feature and Outlook's import settings can move messages between accounts, though the process takes time depending on how many emails you have.
Frequently Asked Questions
Can I change my email address username?
No. The part before the @ symbol is permanent and cannot be changed. If you need a different email address, you must create a new account with a new username. You can set up forwarding from your old address to your new one so you do not miss messages.
Will changing my display name log me out?
No. You stay logged in the entire time. The change takes effect when ready on new emails you send, though it may take a few minutes to sync across all your devices.
Can I have different display names for different email addresses?
Yes, if you have multiple email addresses in the same account. Gmail, Outlook, and Yahoo all let you set a different display name for each address in your "Send as" or "Send from" settings. Each address can show a different name when you send from it.
What if I forgot where to find the display name setting?
Look for "Settings" or your profile picture in the top right corner of your email. Then search for "Name," "Profile," or "Account info." All three major providers keep the display name setting in their account or profile section, usually within two or three clicks.
Does changing my display name affect my password or security?
No. Your password, two-factor authentication, recovery email, and all security settings stay the same. Changing your display name is a cosmetic change that does not touch any security features of your account.
