Someone enters a journey and an email is fired to that person. However I would like all registers in a DE to receive that email. Is it possible to include them inside the CC/BCC functionality?
If you add a column called CC(or something that makes sense to you) to your DE with as a default value for that field the emailaddress you want to CC/BCC, you can use a personalization string to add this to the CC/BCC field.
It's not out of the box but it does the trick.
