Sending From Multiple 'From' Addresses in macOS Mail

If you have multiple email accounts and want to use them for sending mail on your Mac running the macOS, you can configure the Mail application to use them on an as-needed basis so that you can send mail from different email addresses.

A scenario where this is best used is when you have multiple email accounts, but you don't receive mail on some of them. Maybe you have one that's used only to forward messages to other accounts, and you don't need full access to it, but you want to send mail from it.

How to Send From Different Email Accounts

Configure macOS Mail to use multiple email addresses:

1. Launch the Mail application on your Mac by clicking its icon in the Dock.

2. From Mail in the menu bar, select Preferences.

3. Click the Accounts tab at the top of the Mail General preferences screen.

4. Select the desired account you want to have multiple From addresses associated with by clicking the account name in the left panel.

5. In the Email Address field, select Edit Email Addresses and then enter all the email addresses you want to be able to use with this account.

6. Exit the Accounts preferences screen.

You can now send mail from any of the email addresses you set up.
