How to Change the Sent From Email Address on a Mac
Mac uses with multiple email addresses and email accounts configured in the Mail app will likely find themselves wanting to change the email address that a particular email is sent from. This is different from changing the default email account on a Mac, as this approach allows the Sent From address to be changed anytime on a per-email basis without setting the default email to something else.
You will need to be using the Mail app in Mac OS and have at least two email accounts setup to be used in the app. You can add a new email account to the Mac Mail app at any time from a service like Gmail, Hotmail, Yahoo, Outlook, AOL, or make a new iCloud email address easily.
Changing the Sent From Email Address on a Per Email Basis in Mac Mail
This will change the Sent From address for the currently composed email only, it does not change the default email on the Mac.
- Open the Mail app for Mac if you have not done so already and compose a new email
- Hover the mouse over the name next to the “From:” section and click on the pull down menu
- Choose the email address you want to send this specific email from
- Confirm the email address is what you want to send the email from and send your message as usual
Note if you do not see the “From:” dropdown menu option it is likely because you do not have more than one email address setup in the default Mail app and perhaps instead have one setup in another third party email client, in which case you’d want to add an additional email address to the Mail app to gain access to this feature..
This change is only for that specific email composition, that means the change to the Sent From address will not carry forward to another new email. If you do want to change every email address to default to something else, then you’d want to set the default email account in Mail for Mac to something else as described here.
This ability is pretty similar to how changing the Sent From address on iOS Mail works too, it’s a little hidden at first glance but it’s super easy to use once you know it’s there.
