### "It just works"

August 26, 2019

5.0

We primarily use Postmark to send out login information, alerts, notifications, and reports from our applications. We do not send a ton of emails out monthly, but we do send thousands a month. If they don't reach our client, that is bad for us. We were able to use industry standard packages to send through Postmark, so it was not difficult to integrate into our applications. We have a couple of cloud applications that we built from the ground up. We tried SendGrid and Mailgun and why both worked, it was more complex and really did not help if messages did not go through. With Postmark it is very quick to see what happened and why.

Pros

In-depth tracking allows me to see why something might have not worked Never gets blacklisted Walks you through the setup Easy to integrate for both simple and complex use

Cons

Cost is a little higher than others, but not too much.

Reason for choosing Postmark

It just works and it works well. Support has been there, when needed. Even during testing we were able to get support quickly and help resolve any issues we had.

Had too many issues with SendGrid and could not easily get help to correct them. Spent too much trying to fix something, versus working on our own products.

### "Superman like delivery for transactional emails"

February 18, 2025

5.0

I've recommended most of my clients to Postmark because they deliver emails. They are one of the best! They are currently a small company but I've tested them very well for transactional emails and never had any issues. Slightly premium from the rest of the companies but if you have the requirement for a good chunk of transactional emails, just go for it! They also have a bootstrapped start-up credit program for those who wants to some credits to start with. They give out about $75 if they think you fit their requirements for bootstrapped start-up program.

Pros

Superfast email delivery for transactional emails, reliability, trust score in the industry and tools for suspension of emails.

Cons

They don't have a 24 hours support and they take their sweet time to respond! While they do get back and I'm happy, if the support is fast, it would be fanstastic.

### "Postmark used to be amazing... RIP Postmark"

July 9, 2025

1.0

Postmark used to be amazing before it was bought by ActiveCampaign. I used to recommend it to all my friends, colleagues and clients. I no longer do. I have lost so many emails due to sneaky changes in their pricing tier without proper notice and extremely poor customer service. While they used to care about the customer most than anything, they've now become soulless, uncaring and unapologetic. RIP Postmark.

Pros

It's easy to set up and get going quickly, though the manual verification step that is required to send real emails is slow and annoying.

Cons

Sneaky business practices, poor customer service, price gouging, lack of helpfulness when resolving issues, and deceitfulness.

### "The Ultimate Solution for High-Deliverability Transactional Emails"

January 25, 2025

4.0

My experience with Postmark was good. It sends email in quick time. But because of it's prizing my client asked to search some other tool.

Pros

Fast Delivery - Postmark’s core focus is transactional emails, and it prides itself on delivering these emails quickly. Simple UI - The dashboard and interface are straightforward to navigate, making it easy for developers.

Cons

Postmark’s pricing is on the higher end compared to other email service providers

### "Simple but effective email client"

June 6, 2023

5.0

Postmark has improved both the look and deliverability of transactional emails in my business, and it's also simplified our email workflows and made it easier for us to analyse and resolve any issues.

Pros

It's really easy to build, sort, and manage your emails in Postmark. You can sort your emails into different servers, each one of which can be split into streams: broadcast and transactional are the main two, which allow you to find specific types of emails easily. Open and link tracking can also be switched on by server, so you have more control over what data you're collecting which helps with GDPR compliance. You can click into each email to see the email body itself and copy any links that have been generated. I can share my account securely with other email addresses, allowing different people within my business to review and have access to our email tools. The API is very easy to understand, allowing you to connect Postmark to other tools easily. There are so many benefits to Postmark!

Cons

The documentation feels a little fragmented - some things are in the official API documentation, while other things missing from the official documentation are included in blog posts or other posts within the Support Center. It would be great if they could all be in one place!

Switched from

[SendGrid](https://www.capterra.com/p/204113/SendGrid/)

SendGrid's functionality was slow and confusing, but most importantly, their customer support failed to support when emails were failing to deliver to all suppliers. I was told this was an issue with their own shared IP addresses that they'd placed my email services on, but that I simply had to wait until I was moved to another IP address and that none of my emails would land in inboxes until that was fixed. This caused untold damage to my business and showed they weren't really that bothered about maintaining the minimum functionality of their product.

### "Our goto 3rd party SMTP provider"

December 8, 2021

5.0

Pricing was a concern at first but well... If we have to pay for a 3rd party provider to deliver our e-mails, we'd rather spend a bit more and have e-mails inboxed rather than discarded or sent to spam. Plus, if you run in any issue, Postmark support usually answers warmly under 24 hours... where the competition usually takes either forever or/and a very cold and super technical approach making you feel like an idiot.

Pros

E-mailing seems simple on the surface. But when it comes to deliverability, it's another story... The support at postmark is super friendly, fast and helpful. And that's well worth the price you pay. The deliverability is overall better than most providers and far superior to any shared host we tried. Their approach to separate marketing and transactional email flows is smart in that matter. You can connect your email flow either through their API... or the old school SMTP, which enables you to send through any software on the market that supports an external integration.

Cons

Honestly, nothing. At some point, they added marketing emails in addition to their core service which is transactional emails. I was a bit frustrated : most SMTP integrations wouldn't work with their initial implementation of marketing emails, as it required to send custom headers along the e-mail. But they took the feedback and a few months later, a workaround was implemented. I can say that this company really has customer satisfaction at heart.

Reason for choosing Postmark

We tried 4 of them on the market (including postmark) and ended up with Postmark. Postmark ranked the highest in our benchmark when it came to deliverability, ease of implementation, support speed & quality (support really cares about their customers' success).

Our customers noticed that our transactional e-mails were getting more and more in spam with our regular shared hosting SMTPs. So we went looking for a 3rd party SMTP to deliver our emails.

### "Reliable and hassle-free email delivery"

October 14, 2020

5.0

We switched over to Postmark from a competitor when we started to have significant email delivery problems. The transition went very smooth since they had a guide on exactly how to transfer from our prior service and what the differences are. It was also easy to update our code to use their new API. Everything has been rock solid so far.

Pros

Postmark has very helpful documentation to explain all their services and it's easy to get started with their guides that help you transfer over from other popular mail services. Their API is well explained and easy to use. Their email delivery is the best I've ever found so far in the industry. I haven't needed to use their customer support much, but when I did they were fairly quick to respond. I like how they include a long email transaction history whereas some competitors only give you 3 days or charge you extra.

Cons

They are not as inexpensive as some others in the industry, but I think their reliability and feature set makes up for the additional cost.

### "The best transactional email solution out there"

February 10, 2021

5.0

As a SaaS platform that sends emails on behalf of our users, we needed an API solution that supported whitelabel domains and solid deliverability. Postmark is the best solution out there in the market for this.

Pros

Postmark knows what they're doing, and it shows. With their deliverability numbers and software design revolving around this philosophy, Postmark makes sure emails get delivered. The email API is also better than the rest.

Cons

The main con of Postmark is the pricing. Compared to other solutions, it's on the pricier side, however it makes up for it as a product and the solution itself.

### "One of the better email senders"

December 18, 2018

5.0

Pros

Before I started using Postmark, I also tried SendGrid and Mandrill. When I came across Postmark, I just stuck with them because it is SO easy to use. I feel like the other companies complicates the process a bit so it can deter users. I manage hundreds of WordPress sites and I set up Postmark for most of them. This gives me a peace of mind that emails are being sent from the sites, which is very important. I've never had a problem with Postmark. I highly recommend it to anyone who is looking to improve email deliverability, especially WordPress sites!

Cons

There was a problem with one site in my account that was sending a lot of spam, and instead of giving a warning, they suspended my account right away. I contacted them and they contacted me the next day, but if I had major accounts depending on Postmark, this would have been a serious problem.

### "There is no better email marketing and transactional email software out there."

December 13, 2019

5.0

Postmark makes it really simple for our company to send transactional emails to our customers. From password resets, to account welcomes, their templates make it simple and straightforward for us to create and send documents and emails easily.

Pros

I love how you can have separate servers for separate emails. Their price is also extremely fair per month, which makes it easy to scale.

Cons

I feel their search functions could be improved. Search is very focused on one server, and not on the whole account. So often when you search, you're not bringing up the full context. You need to dial in to a specific server, to specific emails, then you can search. But there is not global search, which makes it frustrating.

### "Send transactional emails easily"

January 18, 2018

5.0

An efficient tool to send emails that offers ways to look up when emails are sent, if they are opened, how and where they are opened (device type, city, etc). Customers tell us they didn't receive a confirmation and we can see that they did, when and where.

Pros

Postmark is a great tool to send transactional emails like reservation notifications, username reset links, point notifications. They are constantly evolving and making the production stronger by adding useful features

Cons

Some of the features come in half baked. For example, they built click tracking, but does not appear to have individual link tracking. So if your emails have 4 links in there (unsubscribe, view profile, receipt, etc) it won't tell you which one they clicked on. Perhaps that's a tool we need to program separately.

### "Postmark is a great, straightforward service with phenomenal support"

April 26, 2018

5.0

Postmark lets us reliably send transactional email with little fuss, and works well every time.

Pros

We've been using Postmark for years for our transactional email, and we've always found it to be reliable, well built, and a great API to interact with. Our interactions with their customer support have also been great you can tell they're a small, well-run business focusing on doing what they do very well. The pricing is great, as well.

Cons

I'm really reaching to try to come up with anything negative to say here; Postmark is focused on doing a few things, and doing them quite well. We'd love a few very specific features that don't exist yet, but beyond that, I can't think of anything to complain about.

### "Great developer-oriented service for all your transactional emails needs"

April 9, 2018

5.0

Pros

I love the developer-centric route that this service takes, it's so easy for anyone with dev skills to set up Postmark and have it running in little to no time. Their dashboard is one of the best I've used, providing a comprehensive and clear snapshot of the state of your emails. They put great thought and a lot of effort into making sure that your emails get delivered successfully.

Cons

If this is the first time for you setting up a transactional email service, it might take some time to get acquainted with some of the underlying concepts that Postmark uses (e.g. servers or sender signatures) but thy shouldn't discourage you from using it, you will be rewarded with a great and reliable service!

July 25, 2019

We're using Postmark to send all our transactional emails in our SaaS product and we've chosen it over the Sendgrid which frankly speaking, I just couldn't get to work at all. We've been using it for 2 years now and somehow still haven't exceeded the free quota. I'd really like to support the product and wish they charged more or earlier for it. Keep up the good work, Wildbit!

Pros

Once you are configured and setup it just works, period. Postmark feels like it has the reliability of the electricity in your home. It's just there working for you all the time 24/7.

Cons

To be honest there are no cons I can think of. Our developer set it up, and all I see is the monthly bill and aside from that everything works exactly as it should.

This has allowed me to transfer the transactional e-mails on all our client websites. Deliverability is excellent, which is the main point of the service. The price is good too.

Pros

The concept of different 'servers' for separating out your transactional email for each site/software that you hook up is great. It works really well. Deliverability is solid, with great reporting.

Cons

To be honest, there's almost no downside. Small niggle might be the reporting only lasts for a while before it's deleted.

### "Good DMARC setup advice & weekly reports"

October 22, 2019

4.0

It greatly facilitated our initial DMARC setup and deployment and helped us identify mail sources that were legitimate, but non-compliant. We were able to correct them and continue to track the performance of DMARC on our domains

Pros

When we decided to implement DMARC this is the first product we came across that offered excellent information and details about how to setup and implement DMARC. Combined with the fact that they offer a free weekly DMARC reporting service makes them a clear and obvious choice to consider when deploying DMARC.

Cons

The reports are fantastic, but if you need to drill down into specific details to analyze and troubleshoot DMARC issues the software falls short in this regard.

Email management for outgoing emails.

What I like most about this software is the ease of use, options are straightforward and easy to understand. The search tool is powerful and quick as well.
