“It isn’t over-designed for marketing campaigns, but it does what it promises: your emails get sent, you can monitor them, scale up, and troubleshoot issues with good tools. 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.“

### "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.

### "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.

### "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.

### "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.

[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.

### "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

The API is cost-effective and easy to use, and unlike other competitors, we never receive a single marketing phone call.

### "Mailgun is still best in mass email delivery"

April 24, 2026

5.0

Our experience continues to be fantastic, and we continue to recommend Mailgun to clients who need SMTP services. Pricing is still very affordable, and service beats competitors that we're recommending clients migrate to Mailgun from.

Pros

Mailgun was very affordable to get started (they have a free tier) and are scaling well with over 20 active clients using our account for SMTP.

Cons

We haven't experienced any downsides or complications that were due to Mailgun. Clients don't complain about it, so we're content.

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.

### "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.

### "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.

I would recommend Mailgun again in a heartbeat. A powerful tool, handles our emails without any issues, and constantly becoming more powerful.

### "A great mail delivery service that just works!"

March 14, 2025

My overall experience with Mailgun has been positive and is boosted through their integration with Web Hosting Providers especially xCloud.

Pros

If you know your way around DNS records, Mailgun is remarkably easy to set up and just works!

Cons

The pricing can go up significantly after the free tier (but at least they have a free tier)

### "Great SMTP and email API for a reasonable price"

September 20, 2024

5.0

We've used Mailgun for cold email outreach campaign. We were able to deliver tens of thousands of mails with a solid deliverability and extremely high open rates (mostly thanks to a good title). The overall experience has been good and if I had the need I'd use the tool again.

Pros

It has good pricing, is fairly easy to use, and is affordable price. We've achieved a very high deliverability, exceeding our expectations in that aspect.

Cons

Some of the user and account management interfaces were a big challenging to use and navigate. It took us a while to configure Mailgun according to our needs.

September 25, 2023

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

### "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.

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.

### "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.

### "Unacceptable"

September 9, 2021

1.0

Unreliable. 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. I can’t recommend this to anyone having a serious business. There are more reliable and cheaper alternatives out there.

### "Almost a necessity with server configs and email filters!"

June 7, 2018

5.0

Mailgun ensures that emails sent from your site make it the destination email inbox and not the spam folder. Easy to use, free for the first 10,000 and has mail logs. All around, a great product!

Pros

Mailgun ensures that emails from your website actually make it to their destination. With their free tier covering the first 10,000 emails, it's a free solution to a prominent issue: emails getting stuck in email filters or not making it at all. Mailgun is easy to sign up for and easy to integrate into your site, especially if you are using WordPress. Absolutely love the mail logs too - that's come in quite handy on many an occasion.

Cons

As a web developer, I understand the need and value of Mailgun. It can be difficult for new users to understand this though.

### "One of the best SMTP/API mail integration solutions"

June 14, 2018

5.0

10,000 free emails a month, easy to use API, easy to integrate and send emails reliably.

Pros

Mailgun offers 10,000 free emails a month, which is much higher than a lot of the competing services in this category. The web interface is clean and provides you with the information you need right on the landing page. Integrates easy with many services and plugins exist for many platforms (eg Wordpress). API is well documented.

Cons

While the Free tier of 10,000 emails a month is class leading, when you begin entering the paid tiers there are much cheaper alternatives available. Email validation service is pricey for what it is.

### "Finally, emails reaching their destination."

April 30, 2019

5.0

Overall great value for the free tier, 10.000 emails for free plus great deliverability and integration, great for Wordpress users.

Pros

When developing a custom PHP app or using Wordpress you often face the issue of your notifications and customer emails getting stuck or not passing the mails filters. This is a big issue, when for example you are sending out important information like an order confirmation or a ticket for your event and your users are not getting your emails or they are arriving into their SPAM folder. Mailgun has proved superb on improving email deliverability and their logs are super helpful as well, you can track what went wrong if anything. Their interface is easy to use and to the point. Moreover, their free tier gives you 10.000 emails for use, for free. Something great for companies doing product research, I found their API easy to use and easy to integrate with my projects, Wordpress being the easiest: a plugin + an API key/secret. Regarding Wordpress I found Mailgun the best amongst options tried for email deliverability.

Cons

Cost of the paid tiers is pricey if you compare with the alternatives. Everything in Mailgun goes through their API, so if you need a Full UI alongside the API this might not be the best choice.
