To send mail from multiple addresses in your inbox
- After you’ve set up your email addresses and aliases in Gmail, follow one of these tasks:
- If you’re composing a new message, click the From link.
- If you’re replying to a message, click the field where your recipients are listed, then click From.
- In the drop-down menu next to your address, select the address you’d like to use to send your email.
Note: You must already own the address you’re trying to send from.
