I'm posting this as a long-shot, given the activity here has been sparse and replies are few and far between.
Does anyone know if it's possible to configure ListMailPro to send unsubscribe headers? This may help us with providers who are automatically blocking us because they aren't detecting an unsubscribe link (even though we've included it in every email). Now with GDPR implemented we're seeing a rise in rejected email.
Thank you,
