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.

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.

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.

Postmark really impressed us with their focus on transactional emails, instead of just broadcasting.

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.

We‘ve grown from sending 0 to 200,000 transactional emails daily, and Postmark helped us a lot with scaling that process.

Is support included?

Absolutely. We don't charge extra when you need help. All of our customers receive the same incredible support regardless of how much you spend with us.

Is there an additional cost for dedicated IP addresses?

No. However, we advise against dedicated IP addresses for most customers. Until you're at an incredibly high volume, you'll see better results using one of our shared IP addresses. While most providers see delivery issues on their shared IP addresses, we monitor ours carefully to ensure great delivery. You'll never hear us suggest that you pay us more money for better delivery. We stand by the delivery of all of our services with or without dedicated IP addresses.

Why do we 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 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. Our rates range from $1.50 per 1,000 credits to $0.25 per 1,000 credits. If you pre-purchase in larger quantities, we can even offer larger discounts.

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.
