The best at transactional email because 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.
We’re proud to say that makes Postmark the only major email API provider adhering to the email traffic management standard promoted by the world’s most popular inbox providers. And those providers notice, which means that our reputation with ISPs is better and ensures speedier delivery of all your application email.

Looking for dedicated IPs?
Because ISPs are placing more weight on the reputation of your domain, our experience has shown that a well-managed set of shared IPs generates the best deliverability for small and mid-size senders.
That said, dedicated IPs can be beneficial for some high volume senders. At Postmark, we’ll work with you to determine if a dedicated IP makes sense for your messages. When the time is right, we can handle warming up the IP to establish a strong reputation with ISPs.
