Is there a way to have automated workflow emails from the system send a copy to the sending users email? The sales rep (the sender) only gets these emails in their inbox when someone replies

yes, create a workflow field, store the sending email address, then when you send out the email, use the workflow field as part of the emails being sent,

Sending email field is dynamic. I dont think this is possible with a dynamic email

So here is how I did it, Workflow Action, • Set Field Value • Condition: Sales Rep Email Is Not Empty • From Field ◦ Record(Join): Sales Rep ◦ Field: Email

for anyone wondering, in the CC field use {user.email} it triggers it.

Then on your Email Action, CC: {custworkflow_your_workflow_email_id}

yup. It doesnt actually have a home on the workflow itself.
