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. “Mailgun excels as an enterprise‑grade email delivery platform.

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.

CEO Telecommunications Used the software for: 2+ years ### "Disastrous service — avoid at all costs" September 2, 2025 1.0 After years of using Mailgun for legitimate transactional emails only, they suddenly disabled my account without warning because of a flawed automated system. This caused immediate chaos for my SaaS, as transactional emails are mission-critical. I switched providers within 24 hours but kept communicating with Mailgun support out how long they would take to restore the service. It took them 8 days before reactivation. Completely unacceptable. No serious SaaS can rely on a provider that pulls the plug without notice. The new service is superior in every aspect: deliverability, UI, and reporting. MThanks to Mailgun for pushing me to move. Pros The only good thing was being grandfathered into their retired Flex plan, but even that couldn’t make up for their disastrous service. Cons Their automated system falsely flagged my SaaS, disabling all transactional emails without warning. Support was extremely slow making Mailgun completely unreliable for any business.

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 HJ Henrik J. Founder, Developer, Systemadministrator Computer Software Used the software for: 1-2 years ### "Thank you for keeping it simple" November 12, 2025 5.0 Again, I have nothing but positive words to say about your business. 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.

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 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.

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.

Pros Easy to use, works great, and has professional support even for people on a free membership like me. Cons I haven’t delved into the details of Mailgun, so I haven’t seen any cons so far. Switched from [SendGrid](https://www.capterra.com/p/204113/SendGrid/) They deactivated my account right after I created it. I reached out to support and their response was basically “it is what it is.” Review Source CD Clement D. ceo Marketing and Advertising Used the software for: 6-12 months ### "Worst email product and support ever used (RUN AWAY)" August 2, 2022 1.0 Pros sub-accounts management (before getting suspended for no reason) Cons Mailgun disables your account after 6 months working on integrating with it ; out of nowhere, for no reason. + they keep billing you every month (over 600$ at this stage) even though your subscription mentions that you're at 0$/month.

However, the ease of implementation and support by different plugins and software make it a really good tool. DNS is easy to configure so we have no issue with deliverability. The dashboard is also great and offers good logs and graphs. Pros Great documentation, 10k emails on the free plan was great previously for the prepaid plan is okay. Good API and interface. Cons Downtimes and deliverability issues can be daunting.

The one thing that an email services cannot be. Pros Not worth my time to post any pros with their software. Same functionality as competitors. Cons Our email has been down this whole morning. No explanation or response from Mailgun. After many unsuccessful attempts to log in to our Mailgun account, we got a popup saying "We are migrating some systems" -- no warning of this in beforehand either. Email is a very critical part of our business. We assumed Mailgun would be a reliable partner — apparently not. Please stay away from Mailgun.
