If you’re running a SaaS product or need to send reliable notifications/orders/alerts etc, Mailgun performs very well. But if you’re looking for low-effort visual campaign building or non-technical workflows, you might find it a bit too “bare metal” compared to some marketing-oriented platforms.“ October 29, 2025 TT Tommy T CTOComputer Software, 2 - 10 employeesUsed the software for: More than 2 years. “Some advanced features sit behind higher-priced tiers, and pricing for dedicated IPs or email validation can be confusing.“ September 16, 2025 GP Gilbert P DevOPSEntertainment, 2 - 10 employeesUsed the software for: More than 2 years. “Robust API & Documentation: The RESTful endpoints are well‑structured and the SDKs (Python, Ruby, Node.js, etc.) make integration painless once you’ve read the docs.“ November 12, 2025 AA Ayodeji A EngineerComputer Software, 2 - 10 employeesUsed the software for: 6-12 months. “Additionally, some advanced settings may not be beginner-friendly, and you may require technical assistance.“ October 29, 2025 ## Showing most helpful reviews Showing 1-25 of 197 Reviews Sort by: Most Helpful Rating Company Size Reviewer's Role Length of Use Frequency of Use Samuel C. Engineer Telecommunications Used the software for: 2+ years ### "Developer friendly transactional email service" April 2, 2022 5.0 We are solving transactional email needs for a startup I work as a CTO, does a great job there despite pricing not being flexible enough. Pros Mailgun is a service that was created by developers for developers. Their top-tier documentation and code is self-explanatory and should present no issues to integrate in just a few minutes. The service itself is reliable and has the latest bleeding edge features. Their customer support is very effective and can get issues solved promptly. Cons Mailgun's pricing has only gotten pricier and pricier with time. They are not even able to provide discounts that are not in their scheme and it is up to you to simply accept that when there are many competitors on this market. The service itself is very robust but this inconvenient made me think about other options after some above-base level features were needed. Alternatives considered [SendGrid](https://www.capterra.com/p/204113/SendGrid/) Reason for choosing Mailgun Documentation looked robust and easy to work with. Review Source GP Gilbert P. DevOPS Entertainment Used the software for: 2+ years ### "Mailgun – Powerful, Flexible, but Not for the Uninitiated" November 12, 2025 5.0 Mailgun excels as an enterprise‑grade email delivery platform. If your team is comfortable with APIs and you need granular control over routing, suppression, and analytics, it delivers on performance and reliability. However, for small businesses or teams without dedicated developers, the learning curve and pricing model can feel restrictive. It’s best suited when you’re already committed to building custom email workflows rather than relying on a “set‑and‑forget” solution. Pros Robust API & Documentation: The RESTful endpoints are well‑structured and the SDKs (Python, Ruby, Node.js, etc.) make integration painless once you’ve read the docs. Advanced Email Analytics: Real‑time dashboards for delivery, bounce, spam complaints, and click rates give a clear picture of campaign health. Flexible Domain & Account Management: You can add multiple sending domains, set up sub‑domains for separate projects, and manage DNS records through the UI or API effortlessly.à Strong Security Controls: Two‑factor authentication, IP whitelisting, and granular role‑based access keep your credentials safe. Cons Steep Learning Curve: The sheer breadth of options (dedicated IPs, suppression lists, custom routing) can overwhelm newcomers; the UI feels more like a developer console than a user‑friendly dashboard. Pricing Complexity: While free tier is generous for low volume, the cost structure (per‑sent + per‑recipient, dedicated IP fees, and extra features) quickly adds up, making it hard to predict expenses without careful budgeting. Limited Built‑in Email Templates: Unlike some competitors, Mailgun doesn’t offer a visual template editor; you need to craft HTML yourself or use third‑party tools. Switched from [Amazon SES](https://www.capterra.com/p/179662/Amazon-SES/) I moved from Amazon SES to Mailgun primarily because of the need for more advanced routing, analytics, and developer‑friendly tooling that our growing product demanded.

I would definitely refer my friends and colleagues. Pros I really enjoyed the camp email templates security on. It was super helpful very little bugs and issues very well worth the value of the cost. Cons Had a good experience if I had to pick a couple things I disliked about mail gun it would be the learning curve and email management was really confusing Review Source KM Konstantinos M. Fullstack web developer Internet Used the software for: 2+ years ### "An amazing service" January 8, 2026 5.0 Great. Actually more than great. Spectacular. I have never used an easier to setup and higher quality service. Pros It’s ever easy to setup and good pricing. I have never ever encountered an issue. It’s as good as it gets. Cons Nothing honestly it’s great. I have never encountered anything that made me look for another alternative. Alternatives considered [KingMailer](https://www.capterra.com/p/162836/Kingmailer/) Reason for choosing Mailgun I recommend this to some friends because they have crypto currency payments. Switched from [MailSend](https://www.capterra.com/p/248621/Mailsend/) I think it became to expensive, can’t remember it was way too long ago. Review Source HJ Henrik J.

Keep it simple going forward, as you have thus far, and you have one guaranteed customer at least. Pros It is well documented and easy to work with, which, as a developer, means quite a lot. It gives me the options, to keep my mail communication within the EU borders, which is key in my field working with EU businesses. Support has been superb thus far, those few occasions needed. Cons Yet to find any cons. It covers my needs perfectly. I am able to relay mails from self-hosted mail servers, along with using the API for my applications. Literally all I need personally, and these is covered nicely. Switched from [SendGrid](https://www.capterra.com/p/204113/SendGrid/) Couldn't keep our mails within EU borders (at that time at least). Their portal was clumsy. As I recall their API was fine and easy to work with too, but those other pointers made us do the switch. Review Source AP Alan P. Software Engineer Computer Software Used the software for: 2+ years ### "Love their API backward compatibility" October 17, 2025 5.0 I’m highly satisfied and don’t mind paying more for a flexible plan with, for example, modular add-on services. Pros They provide backward compatibility with their old API to reduce downtime during upgrades, especially for legacy systems where upgrading to the latest library or source code is not feasible. Cons The log retention period is very limited. Does not support multiple sub accounts with separate billing and separate payment methods. Switched from [SendGrid](https://www.capterra.com/p/204113/SendGrid/) The API is cost-effective and easy to use, and unlike other competitors, we never receive a single marketing phone call.

We have recommended them to many clients and friends because of the ease of use, reasonable costs, and much better quality of service than competitors. Pros Mailgun was very quick to setup and has continued to serve our mass emailing needs across many websites for several years running. The cost is great, quality of service and deliverability is great. Cons I don't know that we experienced any downsides with Mailgun. Our clients have not complained about it, we have not had to worry about it. Their documentation has been easy to follow. I really don't see a downside. Alternatives considered [Gmail](https://www.capterra.com/p/202338/Gmail/)[Yahoo Mail](https://www.capterra.com/p/266980/Yahoo-Mail/)[Brevo](https://www.capterra.com/p/132996/brevo/)[Microsoft 365](https://www.capterra.com/p/227157/Microsoft-365/)[Zoho Mail](https://www.capterra.com/p/174694/Zoho-Mail/) Reason for choosing Mailgun Ease of use, less restrictions, and lower cost. Switched from [Gmail](https://www.capterra.com/p/202338/Gmail/) Gmail was not a good option for bulk emails across many clients and websites. It was more costly, harder to manage, and just not designed for this purpose. Review Source NH Neil H. Developer Computer Software Used the software for: 1-2 years ### "Mailgun - Works great with your app" September 16, 2025 5.0 Very easy to use, and allows me to provide login verification, password retrieval, etc for the users of the site. Pros It was very easy to integrate with my online platform (Django / HTMX stack), and provided a dashboard for checking problems as well as sandbox for testing. Cons Not had any issues at all that I can complain about, perhaps they could add some extra example code but I didn't need any myself. Switched from [Gmail](https://www.capterra.com/p/202338/Gmail/) Needed a more complete solution, and Gmail was limiting the use of Gmail in automated systems. Review Source BV Brian V. Managing Partner Information Technology and Services Used the software for: 2+ years ### "Solid service to ensure reliable email delivery" June 9, 2025 5.0 It has been a pretty positive service. I ran into some issues with when switched login with Sinch, but other than that we have reliable mail delivery and some tools to analyze issues. Pros In a world where it is becoming increasingly difficult to have business email arrive in someone's inbox, Mailgun has been a great go-to for smaller web applications we've built on the WordPress platform. It is fairly easy to set up if you have experience with DNS, and pretty good instruction if you are not. There are a lot of tools to help you understand delivery, track bounces and analyze issues with your email. Cons Mailgun could use a wizard like interface for setting up a domain. Also it is a bit expensive if you are planning really large scale email delivery. The trade-off of course is that the cheaper services are not as easy to set up as Mailgun. Alternatives considered [Amazon SES](https://www.capterra.com/p/179662/Amazon-SES/)[SendGrid](https://www.capterra.com/p/204113/SendGrid/) Reason for choosing Mailgun Ease of setup and cost where the primary drivers with MailGun.

A powerful tool, handles our emails without any issues, and constantly becoming more powerful. Pros Easy to integrate within our platform, handles high volume email sending without any issues. Cons More visibility on automated changes (such as automatic suppressions) Switched from [Amazon SES](https://www.capterra.com/p/179662/Amazon-SES/) To improve reliability as our platform continues to scale Review Source VR Verified Reviewer Senior software developer Information Technology and Services Used the software for: Less than 6 months ### "A Reliable Solution for Transactional Email Needs" January 16, 2025 4.0 My experience with Mailgun was good. Mailgun is a strong choice for businesses needing reliable, scalable transactional email services. Pros Scalability: Mailgun is highly scalable. Deliverability: Very good email deliverability rates. Support: The support is very responsive with available documentation and 24/7 customer service. Cons Pricing is bit more expensive compared to other tools. Switched from [SparkPost](https://www.capterra.com/p/82543/SparkPost/) SparkPost can be more cost-effective than Mailgun, especially at higher email volumes. Review Source AK Andreas K. Founder/Owner Information Technology and Services Used the software for: 1-2 years ### "Great and reliable" September 25, 2023 5.0 We use Mailgun for a while now and we really like it.Currently we're using it as a standard for all our transactional mailings on new projects.Also, when we experienced difficulties and reached out to the support, we've been amazed about their qualified response that helped us not only solving the problem (mail deliverability) but also to improve the quality of our emails. Pros \+ API mailing+ driver for laravel+ triggers / webhooks+ price/value+ easy setup and integration+ easy deployment on new domains+ fixed IP address if needed+ good support and best practise+ reliable Cons \- logs can not be exported- bad UI for mobile admin access- sometime uses burnt-out IP addresses Alternatives considered [Amazon SES](https://www.capterra.com/p/179662/Amazon-SES/)[Netcore Email API](https://www.capterra.com/p/147847/Pepipost/) Reason for choosing Mailgun Because the integration in our development-stack was best-in-class. Review Source LJ Luke J. Founder Information Technology and Services Used the software for: 2+ years ### "Great Software Gone Greedy" March 25, 2021 4.0 Outside of them changing their payment tier / plan system I haven't had any issue with Mailgun. I always found their customer service great and the product itself to be fantastic and does exactly what it's supposed to. I just really wish they brought back the routing feature to the free tier. Pros Great API, Super easy to integrate into various types of website / webapp setups. I previously used Mailgun for a variety of different integrations and never had any issues. Complete frictionless integration from beginning to end. Cons I dislike that the features we used to get for free are now hidden behind a paywall. Features such as routing emails I find to be rudimentary and were previously built into the free / pay as you go tier. Now it is locked behind the $35 dollar tier. This is a pain for small businesses that want to accept a few emails from a professional email with their own domain. Now to unlock that feature they must over commit to a tier with an allowance of 10k plus emails a month. This I feel has squeezed many small businesses out of using their service and it has definately moved me from recommending & using them in future as I would have previously for my smaller clients. Alternatives considered [SendGrid](https://www.capterra.com/p/204113/SendGrid/) Reason for choosing Mailgun At that point in 2018 it was easier for me to get started with Mailgun and there were more tutorials and information of how to integrate it. Review Source VL Valics L. CEO Internet Used the software for: Less than 6 months ### "Good services, fast response on support." October 15, 2025 4.0 Overall Mailgun is ok, it does what it promises. The service is reliable and support responds quickly when needed. Pros Easy delivery to clients. Fast delivery even when I send out 1000 transactional emails. Easy to understand the onboarding part. Cons Yahoo delivery going to spam, even if I have all green in Mailgun. Delivery is affected and is no solution to use. Switched from [Mailchimp](https://www.capterra.com/p/110228/MailChimp/) Price was better, I pay only how much I use. Review Source SB Steve B. CTO Computer Software Used the software for: 2+ years ### "Easy to use and packed with features." January 10, 2025 5.0 Pros Easy to use API allows for addition of email functionality in all of our apps. Very detailed searchable logs available for each domain. Cons Nothing. The best email delivery platform I have used. Review Source SF Simon F. Arborist Consumer Services Used the software for: 6-12 months ### "Works for us" February 15, 2025 5.0 We’ve found it straightforward to implement and it sends emails successfully. Pros Simple and straightforward email api that I was able to plug into other systems Cons Can be complicated if you’re not technical Review Source Maria C. Owner Retail Used the software for: I used a free trial ### "Mailgun Review" December 24, 2024 3.0 While I'm glad I tried it, I probably won't use it in the future. Pros Mailgun was easy to use, pretty straightforward and user friendly. Cons The software seemed a little generic to me, no frills. Review Source MH Mohammad H. Inbound marketing specialist Marketing and Advertising Used the software for: Less than 6 months ### "Good email service but room for improvement." December 24, 2024 3.0 It is a decent experience; it meets basic email needs effectively. Pros Reliable email delivery with good tracking tools. Cons The interface can feel complex for beginners. Review Source JM John M. Software Engineer Online Media Used the software for: 2+ years ### "Mailgun Review" January 13, 2023 5.0 All of our company's websites utilize Mailgun for email marketing purposes. We've even implemented Mailgun for our customers and strongly suggest it. Email delivery problems have been solved thanks to Mailgun. There is no need for us to use the e-mail server provided by \[our hosting server\]. Email delivery was a major problem for some of our customers who were hosted with well-known shared hosting providers like GoDaddy, Bluehost, etc. One of Mailgun's best features is that messages can be monitored in real-time, and if they fail to send for any reason, the specific cause is shown in the log. Pros Sending an email to someone takes no time at all, and you can even set up a queue for thousands of messages. If you need to contact a large group of people with one message, this is a great feature to have (e.g., newsletter subscribers, marketing emails to clients, etc.). With its help, your emails are more likely to reach their intended recipients and are less likely to end up in the spam or junk folders. The Mailgun reports and logs feature is excellent. If an email couldn't be delivered successfully, what are the exact reasons why? Sometimes, if we can determine the cause, we can work to fix the problem. Cons The WordPress plugin for Mailgun could use some work. It needs to have more options made available to users. Our email volume isn't particularly large, but we'd still like to have a dedicated IP address for our outgoing mail. A dedicated IP's high price tag is unjustifiable. fixing the problems that have arisen with sending emails to Hotmail or Outlook.com. Deliveries are made, but the junk/spam folder is where most emails end up. Review Source Dimitri L. CEO Internet Used the software for: 6-12 months ### "Paid for a service, denied because suspicion of fraud" June 30, 2023 2.0 Wanting to send only notification emails to our users through Mailgun, our very bad experience with the support team killed any interest for the product. Pros Mailgun was easy to set up, straight from Heroku. It worked well for some time. Cons Despite a paid plan and all the proofs the Mailgun staff could need, they restricted heavily our ability to send mails to our users through SMTP. Review Source Sushant K. Co-Founder Education Management Used the software for: 2+ years ### "Consider Mailgun if you want to increase your email delivery rates" November 30, 2022 4.0 Overall it's a great tool to start with if you are a startup doing an initial setup for transactional emails. Just keep an eye on pricing as you scale as we migrated to AWS SES once we started hitting like 50k emails per month because it was cheaper than Mailgun. Pros The integration is smooth, and it's very easy to get started. I felt Mailgun has the best success rates. It keeps giving good suggestions with reporting dashboard to improve the delivery rates. Cons They had changed the pricing plans and removed the free plan, so if you are starting, it's not free anymore. It just has a free trial of 90 days and after that, you need to upgrade the plan. Customer support can be improved as well. I had one issue with my account that got sorted out in about two weeks. Review Source TT Todor T.

Cheaper than most competitors Cons You can not search the logs with the email content Review Source MF Mohamed F. Associate Payments Banking Used the software for: 2+ years ### "Suitable for optimizing email marketing campaigns" January 22, 2023 5.0 Mailgun gave us fresh ideas for planning our email marketing campaigns and the effect of maximizing their reach. Their analysis helped us understand our target sample, which enabled us to coordinate campaigns better. Pros Mailgun's many features make email marketing easy to plan and implement. We can import contacts and create target group lists. Mailgun's custom templates allow you to design unique campaigns and save them as drafts. It's incredible how the real-time notifications and statistics show how actively customers engage in the campaign. My team and I love that future campaigns can use the same model. It's also good that you can hide and reorganize dashboard items. Cons I have no major technical problems. Mailgun improves email workflows for organizations large and small, the creators of Mailgun provide various videos and how-to materials that help develop our skills, and the support staff is always available.

Pros Configuring email is like conjuring drunk dragons with black magic: most of the time it only works so-so and any tiny mistake gets you burned. Mailgun has very good documentation on setting up your domain and configuring things so that your reputation is great and does not suffer. The REST API makes dealing with events a pleasure and the dashboard gives you great insight into where your mails are going to or coming from and why your audience is behaving the way it is. Cons There's not much not to like. The price is great (mostly free) and the documentation and reliability are 100%. Review Source Cuong T. Founder Internet Used the software for: 2+ years ### "The best SMTP provider I love most" August 9, 2019 5.0 Mailgun worked for me seamlessly, no challenge and I'm happy to use it, even will buy their Pro Plan in the future. Pros I use Mailgun for my email marketing services and it works perfectly. Mailgun helped all my emails go straight to my prospectors' inbox instantly without any challenges. With 10.000 free emails/month is a super deal for small business. Besides, Mailgun is truly flexible for developers with Webhook Support, API support, SMTP user manager, Email Template Builder. Cons I hope Mailgun support Email Template Builder with Drag&Drop function that easier for me to create email templates for my workflow.
