This may be answered somewhere else but if so, I've had trouble finding it.
Recently I've noticed that when I send a tracked sales email to an account where there has previously been a soft bounce, I'm not getting any kind of confirmation whether the email was delivered or not.
In these cases we know that the email is correct (as non-tracked emails do not get returned, and tracked emails with the wrong address do get returned), but for whatever reason the delivery status is not being shown on the account.
Has anyone else had any experience with this? Any idea what's causing it or if there is a way to check delivery status?
