Postmark separate message streams
[Postmark](https://saaskart.co/software/postmark) separates transactional and broadcast message streams, which protects transactional deliverability from being affected by bulk sends. Mixing them can hurt reputation; separation keeps your critical email streams clean. Use the transactional stream for system email and broadcast for anything bulk. That architectural separation is part of why Postmark maintains leading deliverability - it prevents the reputation contamination that occurs when transactional and marketing email share the same sending reputation.
