Why choose Postmark over Amazon SES?

You can spend all of your time building tools for someone else to send your email. Or send with Postmark and get all the tools you need, while you build your app.

You can get more than just delivery stats

At Postmark, we put in a ton of work to make sure your messages get delivered. Instead of asking you to trust us when we say we have great delivery, we want to prove it with our live delivery data.

  • Gmail

  • Apple

  • Hotmail

  • AOL

  • Yahoo

Time to Inbox data updated every 5 minutes

That's real data piped in straight from our status page. We share this data because our customers deserve more than claims about great delivery speed, they deserve proof. 

You shouldn't need to dedicate a massive team to have insight about how your transactional messages are performing.

I was shocked to see Postmark open rates were an 11% improvement over SES in our test. Needless to say we started sending all of our transactional email through Postmark.

Great support is included

Support isn't a luxury when you're sending email for an application. You need to be able to reach out and get answers when there is a problem. It shouldn't cost you extra to talk to a human.

With SES, you'll have to manually set up your own services to track and monitor message events. That means building functionality to enable you to suppress delivery to bounces and spam complaints. With Postmark, all of this is taken care of, and you have a rich interface for managing delivery and researching details about each message. Postmark stores this activity for every message for 45 days, and best of all, it's all included. You don't have to write a single line of extra code.

How much does Postmark cost?

Instead of a bill at the end of the month, every email you send or process cost one Postmark credit. These credits don't expire, and you can purchase them in bulk as you need them.

Credits Price/1,000 Min. Cost
1,000+ $1.50 $1.50
200,000+ $1.25 Save 17% $250
500,000+ $1.00 Save 33% $500

Why does Postmark bill with credits?

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

You’re never left with the hassle and expense of switching between monthly plans when your volume fluctuates. Postmark scales alongside you and rewards your success with larger discounts as your volume increases.

What happens when I run out of credits?

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 your 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 discounts work?

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

Do you offer high volume pricing or discounts?

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