Exceptional deliverability for everyone

With MessageBird (formerly 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.

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.

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.

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 MessageBird (formerly 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 by default (and retention can be customized from 7 to 365 days if needed).

If you need to maintain more than MessageBird'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 offers a full set of pre-built and exhaustively tested email templates to help you get started. For each of these templates, we've also written extensive guides about best practices for configuration, usability, engagement, copywriting, and more.

Whether you need more templates or just want to custom-build your own set of templates, we've built and open-sourced MailMason, a complete toolset to streamline building and updating a set of consistent transactional emails. It makes it easier build your emails by enabling you to use partials, automatically inline your CSS (or SCSS), test emails in Litmus, automatically generate text equivalents, and much more.

Don't take our word for it, though...

Postmark every day. UX is great. Delivery is top-notch and super fast. I've also used Sparkpost and Mailgun and they just don't compare.

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.

Personal experience of working with a few other providers recently is that @postmarkapp definitely seems to have the upper hand on speed.
