Looking for an alternative to Mandrill?

Postmark offers great deliverability as standard, and a helping hand whenever you need one.

Exceptional deliverability for everyone

Your customers expect application emails to arrive immediately—not eventually. We don't just claim great deliverability. We share live delivery data so you can judge for yourself.

  • Gmail

  • Apple

  • Hotmail

  • AOL

  • Yahoo

Time to Inbox data updated every 5 minutes

With most providers, when deliverability issues arise, they suggest that paying more for a dedicated IP address will fix the problems. We believe that's an abdication of responsibility to ensure your emails reach customers every time. It’s our job to provide you with great deliverability with or without dedicated IP addresses.

Whether you send thousands of emails or millions of emails, you’ll see the same quality of deliverability across our entire service. You'll be hard-pressed to find a provider more willing to stand by the quality of their shared IPs than Postmark. If or when the time comes that a dedicated IP address makes sense, we'll set you up on one, but we won't charge extra for it.


Great support at no extra cost

Everyone says they have great support. Then you notice they sell an upgraded version of dedicated support for customers who are willing to pay extra.

There’s no VIP section for support with Postmark. You can email us and usually hear back in a couple of hours, or you can reach us via live chat during business hours. If you’re having delivery problems, we’ll never tell you to just upgrade to a dedicated IP address. We’ll dive in and help you get to the bottom of things.

We also have comprehensive developer documentation and a support center packed full of resources to keep you going when our support team is enjoying some well-earned downtime with their families.

Customers that already made the switch

My customers are so confident in their transactional email now, that they no longer include 'check in your spam box' in their website messaging anymore. Account email confirmations and missing invoices are a thing off the past. The activity feed gives myself and my customers total confidence in using email for important tasks again.

I’ve used SendGrid, Mandrill and Postmark for transactional email in production. Amazing how much better Postmark is than everyone else.

You have an excellent user interface and very good spam reputation service. Combined with the pay-what-you-use subscription a better alternative to Mailchimp and its expensive Mandrill moneymaking machine.

Why do we bill with credits?

Because we believe you should only pay for what you use.

By paying for credits up-front, you’re never surprised with a large bill at the end of the month. Postmark scales alongside you, and rewards your success with larger discounts as your volume increases.

What happens when credits run out?

We’ll send you a series of emails when your credits drop below 15% of your last purchase so you know it’s time top-up. If you have auto-renewal enabled, we’ll automatically top up your credits when you’re balance drops to 10%. If you run out of credits, we’ll stop accepting API requests from your app until you top-up your account.

How do the discounts work?

The more credits you buy in a single purchase, the greater the discount you get.

Do you offer high volume pricing?

Yes! Give Marek a call at 1-855-286-7373 or drop him an email to talk more about our pricing.
