SendGrid Alternative

With Postmark, there's no upcharges. You get great (and fast!) support and 45 days of activity history at no charge.

Great support at no extra cost

With SendGrid you'll need to pay extra for an upgraded plan with "prioritized support" for "premier" customers. At Postmark, we give everyone great support, and quickly too. Our average time to first response is under two hours. That's hours, not days. There's no extra charge for premium support.

There’s no prioritized support with Postmark. You can use email, live chat (during business hours), or even schedule time. You'll usually hear back in a couple of hours. If you’re having delivery problems, we won't recommend upgrading 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 centralized 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!

Exceptional deliverability for everyone

With SendGrid you'll need to "boost deliverability with a dedicated IP" and pay them more. 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.

  • Gmail

  • Apple

  • Hotmail

  • AOL

  • Yahoo

Time to Inbox data updated every 5 minutes

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 can set you up on one.


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 SendGrid provides 3 days of message event history and offers 30 days of history as a paid upgrade, Postmark provides a full 45 days of both message events and full content rendering to all accounts at no charge. 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 transactional 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 to build your transactional emails by enabling you to use partials, automatically inline your CSS (or SCSS), test emails in Litmus, automatically generate text equivalents, and much more.


Separate your mail streams with servers

Organize your mail streams by environment, domain, client, or anything really.

With SendGrid, all of your messages get lumped together in one stream making it difficult to search, filter, and troubleshoot. With Postmark, you can organize and separate those mail streams. This makes searching and filtering your activity stream easier and faster when troubleshooting. It also gives you the ability to manage permissions and API usage on a more granular level.

Okay @postmarkapp is amazing. Why has no one told me about this? Good riddance to all their competitors I've put up with for too long.

For outgoing transactional mail I strongly recommend Postmark. Had bad experience @ Mailgun and SendGrid with delivery.

...I've been with Postmark for a few months. Their system is definitely better than SendGrid and SparkPost...two services I tried before moving on to Postmark.

We use Postmark and are very happy with it. Switched from SendGrid due to security problems, dodgy UI, and not storing email content.

I’ve used SendGrid, Mandrill and Postmark for transactional email in production. Amazing how much better Postmark is than everyone else.

On the surface, SendGrid's support looks better, but based on what we've heard from customers, it's not much use if support is available 24x7 if they do a poor job helping when you really need it.
