You can easily set up automatic email forwarding in Yahoo Mail, which lets you send a copy of incoming messages to Gmail or any other type of email service.

Automatic email forwarding can come in handy if you are trying to consolidate all your email to a single account, or if you want to delegate your messages to another person and need to automatically forward all new messages there. 

The step-by-step instructions below are for forwarding Yahoo Mail to Gmail, but is widely applicable to any email service.

How to forward Yahoo mail to Gmail

1. Open Yahoo Mail in a browser window and click the Gear icon at the top right of the page, under the Home icon. If the browser window is wide enough, the gear will be labeled “Settings.”

2. Click “More Settings.”

3. In the pane on the left, click “Mailboxes.”

4. Under “Mailbox list,” click the Yahoo email account that you want to forward.

5. In the Forwarding section, enter the email address where you’d like your Yahoo email to be sent, and then click “Verify.”

After you enter your Gmail address, you’ll need to go to Gmail and complete a few steps to verify you want to forward email there. Dave Johnson/Business Insider

6. Go to the account where you’re forwarding your mail. You should see a new email from Yahoo asking you to confirm that you want to forward your email there. This prevents anyone from maliciously or accidentally forwarding email to an account that doesn’t want the messages. Confirm that you want to forward the email. Your Yahoo Mail is now  automatically forwarding to Gmail.

You can cancel email forwarding by returning to this same Yahoo Mail menu and clicking “Remove.”
