Fast email delivery that you can rely on.

Do you know how fast your transactional emails are delivered? You need to.

Your customers don’t frantically refresh their inbox waiting for your next newsletter but their password reset email is another story. If it doesn’t hit their inbox instantly, they care, and then they email support.

The extra support burdens your team and hurts your reputation. Your password resets, license keys, account confirmations, and other transactional emails are critical to your business, and it’s imperative that they arrive in your customers’ inboxes immediately.

Time to inbox right on our TTI page.

We send a lot of email, but even spammers can claim to send billions. Email delivery is what really matters, and we don’t just claim great delivery. We share our email delivery metrics for transactional email right on our Time to Inbox page.

Speed is at the core of what defines Postmark as email delivery service. Even a 30-second delay to Hotmail addresses gets us out of bed in the middle of the night.

Great email delivery is included. It’s our uptime.

Delivery shouldn’t be an add-on or up-charge, and you definitely shouldn’t have to sit through a sales call to get improved email delivery. We believe that every customer deserves great delivery. It’s just part of the deal when you use Postmark. It’s our uptime.

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.

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.
