Mandrill vs Postmark: What are the differences?

Developers describe Mandrill as "Send transactional, triggered, and personalized email, then track results". Mandrill is a new way for apps to send transactional email. It runs on the delivery infrastructure that powers MailChimp. On the other hand, Postmark is detailed as "Email delivery for web apps - done right". Postmark removes the headaches of delivering and parsing transactional email for webapps with minimal setup time and zero maintenance.

Mandrill and Postmark belong to "Transactional Email" category of the tech stack.

Some of the features offered by Mandrill are:

Inbound Email- Set up inboxes for Mandrill to control. When they receive email, we’ll make an API call to your app with all the relevant information, so you don’t have to worry about what’s happening behind the scenes.
Webhooks Support- Create custom event notifications, keep track of new signups and unsubscribes in real-time, get a notice of every spam complaint so you can flag them in your database.
Rules Engine- Modify the content of email coming through Mandrill without having to involve developers. For example, you could tell Mandrill to take any email coming from confirmation@yourdomain.com, give it a new template, and add Google Analytics tracking.

On the other hand, Postmark provides the following key features:

Create a new virtual server- Instant access to our infrastructure, no waiting required. Create as many servers as you want, for each of your web applications and environments.
Drop code into your app- Swap in our SMTP endpoint, or get started with our APIs using one of our send API libraries for Ruby, Rails, .NET, Python, PHP, and more.
Send emails and track delivery- A beautiful interface to monitor volume, bounces, spam complaints, and send activity. View full email content to troubleshoot issues.

Advice on Postmark, Mandrill

Kevin

Jun 29, 2021

Decided

We chose Postmark as our transactional email service for several reasons:

Laser-focus (at the time) on transactional email - their success/speed/reliability with delivering transactional email is amazing. Note, they have now branched out and offer marketing/broadcast email services too.
Developer-friendly - Awesome docs and resources. Their Rail gem integrates directly with ActionMailer so nearly all of our code worked without changes.
Servers - You can set up "Servers" for different mail streams/workflows to keep things separate and easy to review.
Bootstrapped - Wildbit (who makes Postmark) is bootstrapped just like the Friendliest.app and they offer a service credit to other bootstrapped startups.

Of course we chose Coresender to send our own transactional emails :) So I thought I'll let you know how we use it.

We set up separate sending accounts for all company needs, eg. transactional emails, monitoring alerts, time to inbox. We even configured our office printers to send emails through Coresender.
We have a real-time and extremely usable view into what emails go through each account, so each time anybody reports an email not arriving we're able to assist them in a few seconds
We utilize our message timeline feature, so we can learn eg. if people are clicking on password reset links
We always know how many of our onboarding emails are being opened which helps us improve them
Finally, we have full controll over our suppressions lists, so we can add (and remove!) from them whenever necessary.

To sum up, at Coresender we're eating our own dogfood and it helps us stay connected to the product and understand our customers better.

We did a quick test on the reliability of these three common email services, sending a few emails an hour at random intervals.

Unfortunately, none of them had 100% availability over the 30 day test. I don't understand why this is so hard?

Mailgun performed the best with the most reliability and fastest response times. Mandrill was notably bad.
