Mailgun vs Postmark vs SendGrid: What are the differences?

Introduction

In this markdown code, I will provide key differences between Mailgun, Postmark, and SendGrid for use in a website.

  1. Email Deliverability:

    • Mailgun provides a deliverability rate of 99.99%, ensuring that emails sent through their service reach the intended recipients' inbox with minimal chances of ending up in spam folders.
    • Postmark also boasts a high deliverability rate, ensuring that emails are successfully delivered to their destination.
    • SendGrid, on the other hand, has a slightly lower deliverability rate of 98-99%.
  2. Email APIs and Integration:

    • Mailgun offers a powerful and easy-to-use API that allows developers to send, track, and receive emails effortlessly. It also provides seamless integration with popular programming languages and frameworks.
    • Postmark emphasizes simplicity and ease of integration, providing a straightforward API for sending and receiving emails with minimal setup required.
    • SendGrid offers a flexible API and extensive documentation, making it easy for developers to integrate email functionalities into their applications.
  3. Email Templates and Personalization:

    • Mailgun supports the creation of custom email templates, allowing for personalized emails with dynamic content. It also provides a templating language to enhance email customization.
    • Postmark offers a user-friendly template editor and supports building email templates with dynamic content and personalization.
    • SendGrid provides a drag-and-drop editor for creating visually appealing email templates, making it simple for both technical and non-technical users to design personalized emails.
  4. Email Analytics and Tracking:

    • Mailgun provides comprehensive email analytics and tracking, including data on opens, clicks, bounces, and unsubscribes. This allows users to gain insights into email engagement and improve campaign effectiveness.
    • Postmark offers detailed delivery and engagement metrics, including information on opens, clicks, and bounces. This helps users better understand the performance of their email communications.
    • SendGrid provides robust email analytics with real-time tracking, enabling users to monitor email delivery rates, engagement, and performance.
  5. Pricing Structure:

    • Mailgun offers a flexible pricing structure based on email volume, with a free plan option for low-volume users. Paid plans offer additional features and support options.
    • Postmark's pricing is based on the number of emails sent per month, with a range of plans to accommodate various needs. They also offer a free plan for low-volume usage.
    • SendGrid offers a variety of pricing plans tailored to different usage levels and provides a free plan as well. Flexibility and scalability are key aspects of their pricing structure.
  6. Support and Documentation:

    • Mailgun provides extensive documentation, API reference guides, and support resources like FAQs, a knowledge base, and a community forum. They also offer email and live chat support for paid users.

Advice on Twilio SendGrid, Mailgun, Postmark

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.

Decided

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.

Decided

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.
