I would like to send an email alert using flow action to the user previous email address when they make a change to the email address. I have a field called previous email address on the Person Account. How can I reference this field from the user object?

Hi Negel, 

It sounds like you're using Person Accounts, so how is this email address being updated? Is an internal user going to the Person Account record and making the update, or is the customer making the update on their own, and if so, how is that being done. 

Also, if a user changes their email, do you have a separate process that updates the Previous Email field? 

Thanks,

Mikey
