Hi Anthony,
At this time we do not offer the ability to change the send from address. All emails will come from "Xerox Gallery App". You can enter your from address (ex. Anthony.Lee@xerox.com) into the Reply To email address so that if they recipient wants to reply to your email they already have the email address entered. Hope this helps! If you have any other questions, feel free to post again. Thanks!
Thanks,
XAG Admin
