I just did a very simple program - uploaded 10 contacts into a static list, set up a campaign where an email was sent to those contacts, but all of them soft-bounced. I made it so they'd get a specific email based on the value in their ListSource, so would that have something to do with it? Is it the validity of the email address?
It could be many thing, but most likely a anti-spam issue, which can be itself triggered by the sender address, the object, the content... you name it.
Look as the bounce reason / bounce cause lead fields to see whether they are giving you more info.
Well, it said "System send failure: Reply-To address parse error ()" Does
that mean it needs to be a valid Reply To address? Would that be the only
thing holding it back?
