Why choose Postmark over SparkPost?

Save yourself the hassle of tracking down lost emails. Choose Postmark to enjoy great deliverability as standard, and a helping hand whenever you need one.

Exceptional deliverability for everyone

With SparkPost you'll need to pay extra for their "Premium" Add-On Plan to get Global ISP relations and mediation and deliverability data analysis, we handle this for all of our customers at no charge because, as an email service provider, we believe that's our responsibility to you.

  • Gmail

  • Apple

  • Hotmail

  • AOL

  • Yahoo

Time to Inbox data updated every 5 minutes

At Postmark, great deliverability isn't an up-charge. We don't just claim great deliverability. We share live delivery data so you can judge for yourself.

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

You shouldn't have to pay for an upgraded version of dedicated support. At Postmark, amazing support is included for everyone.

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.


We’re here to help!

Unrivaled troubleshooting capabilities

When it's time for troubleshooting, nobody logs and retains more helpful details about the event history and content of messages than Postmark.

While SparkPost provides 10 days of message event history, Postmark provides a full 45 days of both message events and full content rendering to all accounts. If you need to maintain more than SparkPost's 10 days of history, they recommend using their webhook and doing it yourself, and even then, you'll only have events. You won't have any details about the message content. With Postmark, you'll never again have to wonder exactly what happened to an email when a customer emails support.

On top of all the tracking info, in almost four years with Postmark, I can’t remember a single time an outage impacted our business.

Do you offer a free trial?

All new accounts start off on our free developer plan with 100 emails per month. Use it for however long you need, it doesn’t expire.

Do you offer dedicated IPs?

Dedicated IPs are available at no charge to high-volume senders. Read why we think they’re a bad idea for other senders.

What happens if I go over my plan’s monthly email limit?

Extra emails on our paid plans are calculated at the end of your billing cycle and included with your plan cost for the upcoming month.

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?

By focusing on transactional email only, ISPs can build a reputation on consistent, high engagement messages. This allows us to have extremely fast delivery to the inbox without tarnishing our reputation from large promotional email campaigns that sit in the queue.

Do you offer high-volume plans?

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