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.

What payment types do you accept?

We accept payments via Visa, MasterCard, American Express, Diners, and JCB. We do not accept PayPal or Purchase Orders.

Why is Postmark for transactional email only?
