I've been asked to research solutions to a scenario where when a subscriber replies to an email it goes to the sender an additional 3rd party, without the subscriber having to "reply-all".
My plan to handle this issue would be to use a Sender Profile where replies use a Triggered Send, and have the triggered send deliver to the person the subscriber is replying to, and cc/bcc the 3rd party.
The business need is to notify the 3rd party when a customer replies to a particular piece of mail. Are there better solutions for this request?
Edit: I should mention we are an RMM customer.
