Mailgun vs Mailjet vs SendGrid: What are the differences?

Introduction

Mailgun, Mailjet, and SendGrid are all popular email delivery services that provide efficient and reliable methods for sending emails. While they have similarities, there are several key differences between these services.

  1. Pricing: Mailgun offers a flexible pricing structure based on the number of emails sent, allowing users to choose a plan that suits their needs. Mailjet also has a similar pricing model, offering different plans based on the number of emails sent per month. On the other hand, SendGrid provides a tiered pricing model based on the number of emails sent and the features required, making it suitable for both small businesses and larger enterprises.

  2. API and Integration: Mailgun provides a powerful API that allows developers to integrate it seamlessly into their applications and websites. It offers SDKs in multiple programming languages, making it easy to implement. Mailjet also offers a feature-rich API with extensive documentation and libraries in various programming languages. SendGrid, similarly, provides a robust API that is well-documented and has libraries available for different programming languages.

  3. Email Templates: Mailgun offers a templating system that allows users to create and customize email templates, making it easier to maintain a consistent design across multiple emails. It provides a simple yet flexible syntax for template variables and conditional logic. Mailjet also offers a comprehensive templating system that allows users to build dynamic and personalized emails using their drag-and-drop editor. SendGrid provides a similar templating system, allowing users to create customizable email templates using HTML, CSS, and template variables.

  4. Email Analytics and Reporting: Mailgun provides detailed analytics and reporting features that enable users to track the delivery, open rates, and click-through rates of their emails. It also offers event tracking, allowing users to monitor email events in real-time. Mailjet offers similar analytics and reporting capabilities, providing insights into delivery rates, open rates, and click-through rates. SendGrid also provides comprehensive email analytics, including detailed delivery, engagement, and event data.

  5. Email Deliverability: Mailgun focuses on ensuring high email deliverability rates by optimizing their email infrastructure, implementing anti-spam measures, and maintaining strong relationships with ISPs. Mailjet also places emphasis on deliverability by using advanced routing and infrastructure optimization techniques. SendGrid, likewise, has a strong focus on deliverability and provides various tools and features to improve email deliverability, such as automatic link and image caching.

  6. Customer Support: Mailgun offers various support options, including email support and a customer support portal with FAQs and guides. It also has a community forum where users can ask questions and share knowledge. Mailjet provides customer support through email, a help center with detailed documentation, and a community forum. SendGrid offers customer support through email, chat, and phone, as well as a knowledge base and community forum.

In Summary, Mailgun, Mailjet, and SendGrid have differences in pricing models, API and integration options, email templating capabilities, email analytics and reporting features, email deliverability focus, and customer support offerings. These differences make it important for users to carefully consider their specific requirements and choose the service that best suits their needs.

Advice on Twilio SendGrid, Mailgun, Mailjet

Kevin

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.
