Looking for a Mandrill alternative?

Postmark offers great deliverability as standard, and a helping hand whenever you need one.

Exceptional deliverability for everyone

Your customers expect application emails to arrive immediatelyβ€”not eventually. 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'll set you up on one.


Great support at no extra cost

Everyone says they have great support. Then you notice they sell an upgraded version of dedicated support for customers who are willing to pay extra.

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.

Customers that already made the switch

My customers are so confident in their transactional email now, that they no longer include 'check in your spam box' in their website messaging anymore. Account email confirmations and missing invoices are a thing off the past. The activity feed gives myself and my customers total confidence in using email for important tasks again.

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.

You go above and beyond to make sure your customers understand transactional email. The educational material you provide make me want to use you. But then there is also the fact (which made me seek you out in the first place) that you take deliverability very seriously. You fixed a problem I had with deliverability in Mandrill. An awesome service.
