We have been talking about Message Streams for a while, and are starting to provide more people with early access to Broadcast sending. So we wanted to make sure you’ve heard that you’ll be able to send all your application email through Postmark soon — including marketing campaigns.
We know what you’re thinking: won’t what hurt the deliverability of transactional email? We’re happy to say that the answer to that is an emphatic no. How can we be so confident? Well, allow us to elaborate... Watch this 2-minute video for a brief introduction to Message Streams and our new infrastructure.

(Ed. note: No, seriously. Watch the video. I know product videos are usually boring, but this one is definitely not.)
We’re excited to open up early access to Broadcast sending with Message Streams, and we'd love for you to be part of it. Send us a note to request access!
