    1. Postmark separates email traffic through Message Streams, meaning that transactional and broadcast traffic never intersects in Postmark, including IP ranges. This is a longstanding best practice for ensuring optimal deliverability. Transactional message streams are for messages that are usually unique and triggered by a user action like a password reset, opted-into weekly digest, or receipts. Transactional streams do not support bulk messages. Broadcast message streams are for bulk messages that sent to multiple recipients at once like announcements, newsletters, or other application email.
    1. The best at transactional email because we never let them mix with bulk messages. You might say that Postmark has serious street cred with inbox providers. To protect the delivery of your transactional emails, it’s crucial to separate them from your bulk or promotional emails. With Message Streams, we’ve built a parallel but completely separate sending infrastructure for these two different types of emails. We don’t let them mix. Ever.
