Sending promotional emails with Message Streams, explained
Itâs been ~two years since we expanded beyond transactional email so you can send all your customer communications with Postmark. And since âtis officially the season to be sending promotional email 🎁 we thought you would find this reminder useful: you can use Message Streams to send out your promotional emails in the coming weeks⊠and beyond!
Your promotional emails need a Broadcast Stream #
We built Message Streams to optimize deliverability for all your emails: transactional, broadcast, and everything in between.
Each Message Stream you create is classified based on how your email is sent: transactional (sent to a single recipient) or broadcast (sent to multiple recipients). That classification helps us group and route emails into the right sending IPs to optimize deliverability and time to inbox.
So if you are planning on sending promotional or marketing emails,*** youâll need to create a dedicated Broadcast Stream. If you donât, and we detect promotional email being sent through a Transactional Stream, your sending will be paused.

***What kind of messages count as 'promotional'? #
Broadcast or promotional mailings are bulk distributions of the same message to many recipients simultaneously. They are likely to include:
Limited-time offers
Sales campaigns
Event announcements
Discounts, coupons, vouchers, and giveaways
💛 Friendly tip: you should only send your broadcast messages to recipients who have explicitly opted-in to receive them. You may think youâre missing out on reaching all of your customers, but do you really want to email people who arenât interested in hearing from you? Thatâs the sort of sending that results in lower engagement, spam complaints, a poor sending reputation, and ultimately impacts deliverability.
