You can add up to 10 email addresses to a single Gmail account

Gmail lets you send and receive mail from other email addresses without leaving your inbox or switching accounts. When you add another email to Gmail, you're not merging accounts — you're giving Gmail permission to send from that address and receive its mail in your current inbox. This works whether the other address is a Gmail account, a work email, or an address from any other email provider.

The process takes about five minutes and requires you to verify ownership of the email address you're adding. Gmail will send a confirmation code to that address, and you'll enter it to prove you control it.

Key Takeaways

  • You add another email through Gmail Settings under the "Accounts and Import" tab, not by creating a new account.
  • Gmail sends a verification code to the email address you're adding, and you must enter that code to complete the process.
  • After verification, you can send from that address directly in Gmail's compose window by selecting it from the "From" dropdown.
  • You can receive mail from other addresses in your Gmail inbox, but sending from them requires a separate verification step.
  • If you're adding a work email or school email, check with your IT department first — some organizations block this type of access.

How to add a sending address in Gmail

Open Gmail and click the gear icon in the top right corner. Select "See all settings," then click the "Accounts and Import" tab. Under the section labeled "Send mail as," click "Add another email address."

A popup window will appear asking for the email address and name you want to display when you send from this address. Enter the email address you want to add in the first field. In the second field, type the name that will appear in the "From" line when recipients get your message — this can be your full name, a nickname, or any text you choose. Leave the "Treat as an alias" checkbox unchecked unless you're adding a Gmail address (the checkbox only matters for Gmail-to-Gmail setups). Click "Next Step."

Gmail will ask you to confirm that you own the email address. Choose "Send verification code" and click "Send verification code" again on the next screen. Gmail will send a six-digit code to the email address you just entered.

Verifying the email address you added

Open the email account you just added and find the message from Gmail. It will come from noreply@accounts.google.com with the subject line "Gmail confirmation code." Open that message and copy the six-digit code.

Go back to Gmail in your browser. The verification window should still be open. Paste the code into the field labeled "Enter verification code" and click "Verify." If the window closed, go back to Settings, click "Accounts and Import," scroll to "Send mail as," and click "Edit info" next to the address you're verifying — the verification window will reopen.

Once you click "Verify," Gmail will confirm that the address has been added. You may see a message asking whether you want to make this your default sending address. Choose "Yes" if you want Gmail to send from this address by default, or "No" if you want to keep your original Gmail address as the default and choose which address to send from each time you compose a message.

Sending from your new email address

When you compose a new message in Gmail, look at the "From" line at the top of the compose window. Click on your email address next to "From" and a dropdown menu will appear showing all the addresses you can send from. Select the address you want to use for that message and compose normally.

If you set the new address as your default, it will be selected automatically every time you start a new message. You can still switch to a different address for any individual message by clicking the dropdown.

Receiving mail from other email addresses

Adding a sending address is different from forwarding mail from another account into Gmail. If you want Gmail to receive messages sent to another email address, you need to set up forwarding from that account to your Gmail address.

Log into the other email account (the one you want to forward from). Look for Settings or Account Settings. Find the forwarding or mail forwarding option — the exact location varies by provider. Enter your Gmail address as the forwarding destination. The other email provider will send a confirmation code to your Gmail address. Enter that code in the other account to complete the setup. After that, any mail sent to the other address will automatically appear in your Gmail inbox.

Troubleshooting verification problems

If you don't receive the verification code, wait a few minutes — it can take up to 10 minutes to arrive. Check your spam or junk folder in case Gmail's message was filtered. If it's not there, go back to Gmail Settings, click "Accounts and Import," find the address under "Send mail as," click "Edit info," and request a new code.

If you're adding a work email or school email and the verification fails, your organization may have restrictions on this type of access. Contact your IT department or help desk to ask whether they allow Gmail to send from your work address. Some organizations require you to use their own email client or block third-party access entirely.

If you see an error message saying the address is already associated with another Google account, that email address is linked to a different Gmail account. You cannot add it to your current account unless you remove it from the other one first. Sign into the other Google account, go to Settings, find the address under "Send mail as," click the delete icon, and confirm. Then try adding it to your current account again.

Managing multiple addresses in Gmail

You can add up to 10 email addresses to a single Gmail account. To see all your addresses, go to Settings, click "Accounts and Import," and look at the "Send mail as" section. Each address will be listed with an "Edit info" button and a delete icon.

If you want to remove an address, click the delete icon next to it and confirm. You can add it back later if you change your mind. If you want to change the display name associated with an address, click "Edit info," update the name field, and click "Save changes."

Frequently Asked Questions

Can I add a Gmail address to another Gmail account?

Yes. When you add another Gmail address, check the "Treat as an alias" checkbox. This tells Gmail that both addresses are yours and belong together. You won't need to verify the other Gmail address because Google already knows you own it.

What happens to mail sent to the other email address?

Adding a sending address does not automatically forward incoming mail. Mail sent to the other address stays in that account's inbox unless you set up forwarding separately. If you want to receive that mail in Gmail, log into the other account and set up forwarding to your Gmail address.

Can I change which address is my default?

Yes. Go to Settings, click "Accounts and Import," find the address you want to make default under "Send mail as," click "Edit info," and check the box that says "Reply from the same address the message was sent to." This makes Gmail remember which address received each message and reply from that same address automatically.

What if I want to use a completely separate Gmail account instead?

If you prefer to keep accounts separate, you can switch between Gmail accounts without adding addresses. Click your profile picture in the top right corner of Gmail and select "Add another account." Sign in with the other Gmail address. You can then switch between accounts by clicking your profile picture and selecting which account to use.

Do I need to verify every email address I add?

Yes, except for other Gmail addresses when you check "Treat as an alias." For all other email providers, Gmail sends a verification code to confirm you own the address. This is a security measure to prevent someone from adding your email address to their Gmail account without permission.
