What a Gmail alias is and why you might want one
A Gmail alias is an alternate email address that sends and receives mail from your main Gmail inbox. When you create an alias, you're not creating a separate account — you're creating another name for the same account. Mail sent to your alias arrives in your main inbox, and when you reply from an alias, the recipient sees that alias address, not your primary Gmail address.
People use aliases for different reasons. You might create one to keep work email separate from personal email while using a single inbox. You might use an alias when signing up for services you don't fully trust, so your main address stays private. You might create one for a specific project or role, then retire it later without losing access to the messages it received.
Gmail offers two ways to create aliases: the straightforward method using your existing address, and a more powerful method using Google Workspace (the paid business version). This guide covers both.
Key Takeaways
- A Gmail alias is an alternate address for your existing account, not a separate email account.
- The simplest alias method uses a plus sign: send mail from yourname+alias@gmail.com, and it arrives in your main inbox.
- Gmail's "Send mail as" feature lets you create and manage multiple aliases with custom names and reply addresses.
- Aliases created with a plus sign work when ready, but recipients see the full address including the plus sign.
- Google Workspace accounts can create professional-looking aliases without the plus sign, but require a paid subscription.
The plus sign method: the fastest way to create an alias
Gmail automatically treats any address with a plus sign as an alias of your main account. If your Gmail address is james@gmail.com, you can when ready use james+shopping@gmail.com, james+work@gmail.com, or james+anything@gmail.com. You don't need to set anything up — it works right now.
Mail sent to james+shopping@gmail.com lands in your main inbox alongside mail sent to james@gmail.com. You can filter these messages, label them, or create rules so they sort automatically. When you reply to a message that came to your alias, Gmail shows the recipient your main address unless you change the reply-from address in your settings.
The downside: recipients see the plus sign and everything after it. If you sign up for a service using james+shopping@gmail.com, that's the address the service has on file, and it's visible to anyone who sees your account details there. For casual use or throwaway signups, this is fine. For professional or ongoing communication, you'll want the second method.
Creating a custom alias with "Send mail as"
Gmail's "Send mail as" feature lets you create aliases that don't include a plus sign. Open Gmail, click the gear icon in the top right, then select See all settings. Go to the Accounts and Import tab.
Under "Send mail as," click Add another email address. Enter the name you want to appear in the "From" field (this can be anything — "James Rodriguez," "Work Email," "Support Team"). Then enter the email address you want to use. Gmail will send a confirmation email to that address.
If you're using a standard Gmail account (not Google Workspace), the address you enter must be one you already own or control. You can't create a brand-new address like james.work@gmail.com from a personal account — you can only add addresses you already have access to. Google Workspace accounts can create new addresses under their domain.
Once you confirm the address, you can send and reply from that alias. In the compose window, click the "From" field to switch between your main address and any aliases you've set up. Recipients see whichever address you sent from.
Setting up aliases in Google Workspace
If you use Gmail through Google Workspace (the paid business service), you have more control. Your administrator can create aliases that look like separate addresses — james.work@yourcompany.com, for example — without creating separate accounts.
In Google Workspace, go to the Admin console, select Users, then click the user account. Under User information, find Email aliases and click Add an alias. Enter the new address and save. The alias is active when ready.
Workspace aliases work the same way as personal aliases: mail to the alias arrives in the main inbox, and you can send from either address. The difference is that Workspace aliases look professional and don't require a plus sign or a second email account.
Managing and organizing mail from your aliases
Once you have aliases set up, you'll want to organize the mail they receive. In Gmail, create a label for each alias or group of aliases. Go to Settings > Labels and click Create new label.
Then set up a filter to automatically label incoming mail. Go to Settings > Filters and Blocked Addresses and click Create a new filter. In the "To" field, enter your alias address. Click Create filter, then choose explore the label and select the label you created. Now all mail to that alias gets labeled automatically.
You can also create separate filters for different actions: archive mail from certain aliases, mark it as read, or skip the inbox entirely. This keeps your main inbox focused on what matters while preserving all your alias mail for later.
Retiring an alias or changing how it works
If you stop using an alias, you don't have to delete it. Mail sent to it will still arrive in your inbox. You can straightforward stop using it, or you can set up a filter to automatically archive messages from that address so they don't clutter your inbox.
If you created an alias using "Send mail as" and want to remove it, go back to Settings > Accounts and Import > Send mail as, find the alias, and click the delete icon next to it. You'll no longer be able to send from that address, but any mail already received there stays in your inbox.
Plus-sign aliases can't be deleted because they're not separate addresses — they're just variations of your main address. If you want to stop using one, straightforward stop signing up for services with it.
Common reasons aliases don't work the way you expect
If you created an alias but mail isn't arriving, check that you're using the exact address you set up. Gmail is case-insensitive, so James+Work@Gmail.com and james+work@gmail.com are the same, but a typo will send mail somewhere else.
If you set up a "Send mail as" alias and the confirmation email never arrived, check your spam folder. If it's not there, the address you entered may not be one you control. You can only add addresses you have access to — you can't create a new Gmail address as an alias from a personal account.
If you're replying from an alias and the recipient sees your main address instead, check your Gmail settings. Make sure the alias is set as a "Send mail as" address, not just a label or filter. In the compose window, always click the "From" field to confirm you're sending from the right address.
Frequently Asked Questions
Can I create an alias that looks like a different email service, like james@yahoo.com?
No. You can only create aliases using addresses you already own. If you want to receive mail at a Yahoo address and have it go to Gmail, you'd need to set up mail forwarding in Yahoo itself, which is a different process. Gmail aliases must use Gmail addresses or addresses under your Google Workspace domain.
If I create an alias, can the person who receives my email reply to it?
Yes. When you send from an alias, the recipient sees that alias address and can reply to it. The reply arrives in your main Gmail inbox. You can then reply again from the same alias, and the conversation continues with that address visible to the other person.
Do I need a separate password for my alias?
No. An alias is not a separate account, so it uses the same password as your main Gmail account. You log in once and have access to all your aliases. If someone gains access to your main Gmail password, they can send from all your aliases.
Can I use an alias to sign up for a Gmail account?
No. When you create a new Gmail account, Google requires a phone number or recovery email address. You can't use a Gmail alias as the recovery address for a different Gmail account. You'd need to use your main Gmail address or a completely separate email service.
What happens to mail sent to an alias after I delete it?
If you delete a "Send mail as" alias, you can no longer send from that address, but mail already received there stays in your inbox. You can still read and reply to those messages — they don't disappear. Plus-sign aliases can't be deleted, so mail to them will always arrive.
