Mailgun is an email delivery service for sending, receiving, and tracking transactional emails. The company was founded in 2010 and is based in San Antonio, Texas.
In previous years, Mailgun was a popular choice for developers as it is an API-first solution.
Today, after a number of acquisitions in 2021, Mailgun is a part of Sinch company. Sinch company now also owns Mailjet which you can use for email marketing and email automation. Even though they are part of a large enterprise now, both Mailgun and Mailjet are still standalone services. So if are looking for a solution for sending all your emails, you will need to deal with two separate services, pay for two separate plans, and communicate with two separate support teams.
👍 Mailgun Pros
- Pay-as-you-go option that you can activate before you find a monthly plan that fits your sending needs
- Solid functionality for managing transactional emails
- 99.99% uptime SLA offered even on lower plans

👎 Mailgun Cons
- Uncertain deliverability results. Some customers reported issues with the deliverability and sending speed of their transactional emails.
- Mixed customer support ratings In the last 3 years, there is a notable rise in customers that report frustrating experiences with Mailgun support team.
- You need to pay for 2 separate services for transactional emails and email marketing. Combined, it is a more expensive solution compared to providers that include transactional emails and marketing + automation in one service.
- Short message retention time. Mailgun stores messages by default only for 3 days. The period can be extended up to 7 days, but even that is a very short period compared to other providers.
- High learning curve and complicated integration for less experienced users
💰 Mailgun Pricing
Mailgun has monthly plans-based pricing with a free trial.
If you want to send both transactional emails and email marketing + automation, you need to pay for 2 separate services. Mailgun plans (for sending transactional emails) start at $35 per month.

2. Amazon SES
Amazon SES become a popular alternative where customers migrate from Mailgun for reliable delivery. It is the cheapest alternative to Mailgun by far. It is a part of Amazon Web Services and as its name SES “Simple Email Service” states, it offers the most simple and low-level service from all the alternatives on the list. For its robust infrastructure and reliable delivery, it’s trusted by giants like Netflix, Reddit, and Duolingo.
Amazon SES focuses on the technical side of email sending and offers only a very basic dashboard. As it is more a developer tool than an end-to-end product, it’s suitable for integrations with robust systems that need a lot of flexibility and for companies that can allocate a great amount of resources to developing their own email solution.
👍 Amazon SES Pros
- The cheapest alternative with a Pay-as-you-go pricing model
- The most robust architecture
- Fast and reliable email delivery
👎 Amazon SES Cons
- Do-it-yourself approach. It requires a lot of manual effort from your site to get things running. Amazon provides you with low-level tools for email delivery, but all the integration, email template setup, troubleshooting, analytics, etc. is up to you.
- No support included
- No out-of-the-box features like template editor, premade templates, message history, email automation, or contact management.
💰 Amazon SES Pricing
Amazon SES has pay-as-you-go pricing.
If you count emails only, it is the cheapest Mailgun alternative by far. 1000 emails cost $0.1.
SendGrid is a close alternative to Mailgun, mainly focusing on sending transactional emails, now also providing broad-spectrum of services for email marketing and email automation. The company was founded in 2009 and is based in Denver, Colorado. As one of the oldest email providers, it’s used by large tech companies like Uber, Booking.com, Yelp, Spotify or Airbnb. In 2019 SendGrid was acquired by Twilio.
👍 Sendgrid Pros
- One of the oldest and largest platforms for email delivery
- Free plan with basic functionality
- Advanced features for testing & email analytics
- Broad-spectrum of tools and integrations not only for email delivery but also for SMS and WhatsApp
👎 Sendgrid Cons
- Occasional issues with deliverability. Since the acquisition in 2019, there has been a notable rise in customer complaints regarding issues with email deliverability and quality of support, resulting in a significant increase in negative reviews.
- Bad support experience reported by many customers even on paid add-on plans.
- No premade email templates for transactional emails
- Complicated pricing with a lot of add-ons and extra fees for features
💰 SendGrid Pricing
Twilio SendGrid has freemium pricing. If you want to send both transactional emails and email marketing + automation, you need to pay for 2 separate plans.
For sending transactional emails Sendgrid offer a free plan with 100 emails/day and limited functionality. Paid Essentials Transactional plan starts at $19.95 per month. The Pro plan which includes more than 1 team member, 7 days of data history, and 1 dedicated IP starts at $89.95 per month.

With the Basic plan, you can not set up any email automation. The Advanced Marketing plan starts at $60 per month and includes both email marketing and email automation and up to 15 subscribe forms.
Postmark is another Mailgun alternative but only for transactional emails. Similarly to Mailgun, it does not offer software for email automation. For email marketing, in May 2023 Postmark introduced Broadcast Streams, but the functionality is very limited. So, if you need to cover all email delivery, you have to find another email marketing and automation service or choose an alternative that has an all-in-one solution.
👍 Postmark Pros
- Good support
- Solid delivery of transactional emails
- Unlimited team members
👎 Postmark Cons
- Missing functionality for email marketing and automation. If you have a SaaS and need a service to cover all your email-sending activities, you have to find another email marketing and automation service. It lacks features for writing product updates, sending automated emails, setting up welcome email sequences, contact management, and collecting new subscribers.
- No visual editor. Postmark does not have a visual editor for email templates. To create your templates, you have to write the code yourself. And coding emails that do not break is a tough and resource-expensive job.
- Support unavailable on weekends
💰 Postmark Pricing
Postmark is a Mailgun alternative with a similar pricing model for transactional emails. It has monthly plans‑based pricing with a free trial.
100 emails per month are free. Then, the paid plans start at $15 per month.
5. Mailchimp (+ Mandrill)
Mailchimp is the most expensive Mailgun alternative from this list. As the opposite of Mailgun, it is an email marketing first platform. In 2016 Mailchimp merged with Mandrill and started offering also transactional emails as a Mandrill paid add-on. In 2021 Mailchimp was acquired by Intuit and become a part of their global technology platform. Following the acquisition, Mailchimp suffered a number of data breach incidents in 2022 and 2023.
If you are looking for a solution with advanced features for email marketing, Mailchimp could be a good solution for you. But for transactional emails, the functionality might not be as good as Mailgun and other alternatives listed above.
👍 Mailchimp Pros
- Advanced email marketing features
- Landing page builder included
- Solid free plan for email marketing
👎 Mailchimp Cons
- The most expensive alternative.
- Uncertain transactional emails. Even though Mailchimp now offers plans not only for email marketing but also for transactional emails, since the Mailchimp + Mandrill acquisition, it seems like the transactional part of the product is not receiving much focus and development. Some former Mandrill customers report technical issues with the delivery and are migrating to other alternatives.
- Previous data breach issues. Following the Intuit acquisition, Mailchimp suffered a number of data breach incidents in 2022 and 2023.
💰 Mailchimp Pricing
