Is it possible for a message sent from Luminate Online (such as a Participant Center message) to allow for recipients to "Reply-all"?
This functionality does not correspond with Luminate Online's Email Acceptable Use policy. All mass emails sent from Luminate Online must allow the recipient to opt-out (either from campaign email or from Tell-A-Friend/Participant Center messages). Recipients will not be allowed to opt-out of Reply-All messages and may not be constituents who have given explicit consent to receive messages. This can lead to increased spam flags or other deliverability issues.
