Developer friendly transactional email service

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.

Functionality

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.

Reasons for choosing Mailgun

Documentation looked robust and easy to work with.

Mailgun – Powerful, Flexible, but Not for the Uninitiated

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.

Ratings Breakdown

Ease of use

Value for money

Customer support

Functionality

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.

Reasons for switching to Mailgun

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

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.

Functionality

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.

Reasons for switching to Mailgun

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

I’m highly satisfied and don’t mind paying more for a flexible plan with, for example, modular add-on services.

Functionality

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.

Reasons for switching to Mailgun

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

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.

Reasons for choosing Mailgun

Ease of use, less restrictions, and lower cost.

Reasons for switching to Mailgun

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.

Reasons for switching to Mailgun

Functionality

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.
