Mailgun vs Mandrill vs SendGrid: What are the differences?

Comparing Mailgun, Mandrill, and SendGrid for Email Delivery

Sending Capacity: Mailgun, Mandrill, and SendGrid differ in terms of their sending capacity. Mailgun allows users to send up to 10,000 emails per month for free, whereas Mandrill used to offer 2,000 free sends per month but is now an add-on for paid Mailchimp accounts. SendGrid, on the other hand, offers a flexible pricing structure that allows users to choose a plan based on their sending volume, starting from a free tier that offers up to 100 emails per day.
Feature Set: Another key difference between these three email delivery services lies in their feature set. Mailgun provides advanced features like inbound routing, email tracking, and list management, making it a good choice for developers and businesses seeking a comprehensive solution. Mandrill, now integrated into Mailchimp, focuses on ease of use and simplicity, with a user-friendly interface and straightforward email templates. SendGrid offers features like event webhooks, email templates, and A/B testing, catering to businesses with more advanced email delivery requirements.
Email Templates: When it comes to email templates, there are notable differences between the services. Mailgun provides a templating system that allows users to create customizable email templates with variables and conditional logic, enabling dynamic content creation. Mandrill, now part of Mailchimp, offers a drag-and-drop email builder that simplifies the process of creating visually appealing email templates. SendGrid provides a range of pre-designed templates to choose from, making it convenient for users who require quick and easy template creation.
Integration Options: The integration options for these email delivery services also differ. Mailgun offers extensive documentation and libraries for popular programming languages, enabling easy integration into applications. Mandrill, being integrated into Mailchimp, provides seamless integration with the Mailchimp platform and related plugins. SendGrid offers robust API documentation and SDKs for multiple programming languages, allowing users to effortlessly integrate the service into their applications.
Deliverability Metrics: Another important aspect to consider is the deliverability of emails. Mailgun provides detailed deliverability analytics, including delivery rates, opens, clicks, and bounces, providing insights into the success of email campaigns. Mandrill tracks engagement metrics like open and click rates, providing essential feedback for email campaigns. SendGrid also offers comprehensive email analytics, including engagement data and spam reports, ensuring users have the necessary information to optimize their email delivery.
Support and Documentation: Support and documentation play a crucial role in the usability of these services. Mailgun provides comprehensive documentation, developer libraries, and responsive support through chat and email, ensuring users have the resources they need. Mandrill offers support through the Mailchimp support team, with a comprehensive knowledge base and community forum. SendGrid provides extensive documentation, access to developer libraries, and 24/7 support through various channels, including chat, email, and phone.

In summary, Mailgun, Mandrill, and SendGrid differ in terms of their sending capacity, feature set, email templates, integration options, deliverability metrics, and support/documentation provided. The choice between these services depends on individual requirements, such as sending volume, desired feature set, ease of use, and level of support needed.

Advice on Twilio SendGrid, Mailgun, Mandrill

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.
