Yes, you can!
By default all Spoonfed generated emails will be sent from our own email address, ‘firstname.lastname@example.org’.
There are however, a couple of advantages of setting up your own domain to send and receive emails from Spoonfed instead.
The first of those is that, if you set up your own domain, in the unusual circumstance in which an email to a Customer bounces, you will receive a notification that this has happened. If you don't set up your own domain, you won't receive this notification.
The second is that if your Customer replies to the email after you have set up your domain, you will receive their email. If your domain is not set up, their reply is instead sent to email@example.com and you may not receive their reply.
Thus for those two reasons, it is advantageous to set up your own domain.
