Mailchimp vs Postmark: What are the differences?


In this article, we will discuss the key differences between Mailchimp and Postmark. Both Mailchimp and Postmark are popular email service providers, but they have some important distinctions. In the following paragraphs, I will highlight six key differences between these two platforms.

  1. Pricing Structure: Mailchimp offers a freemium model, allowing users to send a limited number of emails for free while charging based on the number of subscribers. On the other hand, Postmark follows a pay-per-use model, where users pay based on the number of emails sent rather than the number of subscribers. This can be advantageous for businesses with a large number of subscribers but fewer emails sent.

  2. Email Deliverability: Postmark has a strong reputation for email deliverability, specifically focusing on transactional emails. Along with robust infrastructure, Postmark follows strict guidelines to ensure high deliverability rates. Mailchimp, on the other hand, is mainly known for its marketing emails and newsletters, which might have slightly lower deliverability rates compared to Postmark for transactional emails.

  3. Email Templates and Customization: Mailchimp provides an extensive range of pre-designed email templates, offering flexibility and ease of customization. With drag-and-drop functionality, users can easily create visually appealing emails without relying on any coding skills. In contrast, Postmark focuses more on the transactional side and provides minimal email templates, prioritizing control over email content and customization.

  4. Automation Capabilities: Mailchimp excels in providing automation features, allowing users to set up email sequences, triggered emails, and personalized campaigns easily. It provides a wide variety of pre-built automation workflows, making it suitable for businesses looking to enhance their marketing automation. Postmark, on the other hand, lacks these extensive automation features, as it primarily focuses on delivering transactional emails.

  5. User Interface and Ease of Use: Mailchimp offers a user-friendly interface with a visually appealing design, making it easy for beginners to navigate. It provides a comprehensive dashboard with intuitive features that simplify the email marketing process. Postmark, although it has an intuitive interface, targets more technically inclined users who prefer a focused and straightforward interface without many additional marketing features.

  6. Support and Documentation: Mailchimp has a comprehensive support system in place, including email support, live chat, and extensive documentation. They also have a vast community forum where users can seek help and advice. Postmark, although it also offers reliable support, focuses more on delivering exceptional transactional email service. The documentation provided by Postmark is thorough and covers everything from setup to troubleshooting.

In summary, Mailchimp offers a freemium model, provides extensive email templates and automation features, and has a user-friendly interface and comprehensive support. On the other hand, Postmark follows a pay-per-use model, focuses on transactional email delivery, provides minimal email templates, lacks extensive automation capabilities, and targets more technically inclined users.

Decisions about Mailchimp and Postmark

While building our authentication system, we originally picked Mailgun. However, emails took minutes to arrive and some of them didn't get delivered - or got delivered to spam.

We started looking for a new provider, and settled on Postmark. We love that they track time-to-inbox, it makes me feel they really care about going above and beyond to provide a good service.
