Can you send bulk/marketing email with Postmark? Yes!
From its very beginning in 2009 and for the entire first decade of its existence, Postmark was well-known for being laser-focused on transactional email only. Then sometime in 2020 we built a fully separate infrastructure that allows Postmark customers to also send bulk emails like product announcements, newsletters, and updates to terms-of-service...
...but some people (maybe including you? 😉) still donât know we can do both!
So if you came here wondering âCan I send bulk/marketing email with Postmark?,â the answer is: yes, you can! You can send all your customer communications with Postmark, and this is how you do it.
Sending promotional and marketing emails with Postmark #
Postmarkâs unique infrastructure routes different types of emailâtransactional, broadcast, and everything in betweenâthrough separate Message Streams so they all maintain optimal deliverability.
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 just need to create a dedicated Broadcast Stream.

***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.
