How Can I Remove "On Behalf of" in Gmail?

Updated November 25, 2019

Emails you send from Gmail using another email address appear in Outlook as "from [me]@gmail.com on behalf of [me]@[example].com"? Here's how to remove "on behalf of" from Gmail.

How Can I Remove "On Behalf of" in Gmail?

To remove "on behalf of" and your Gmail address from messages you send in the Gmail web interface using another email address, you can set up Gmail to send mail via the alternate email address server.

Click the Settings icon in Gmail.
Select Settings from the menu.
Go to the Accounts and Import tab.
Under the Send mail as heading, click edit info next to the other address you use with Gmail.
Select Next Step.
Select Send Through SMTP Server.
Enter your email user name (usually either the full email address or what Gmail has already entered) under Username.
Type the email account's password under Password.

Typically, make sure Secure connection using TLS is selected.
If the SMTP server only supports secure SSL connections, make sure Secure connection using SSL is selected for sending mail.
Verify the SMTP port is correct: with TLS, 587 is the typical port; without, 465.
Select Save Changes.

Using these settings, Gmail will use your other email address's servers. Since Gmail is no longer the originating domain, there will be no more "on behalf of."
