Co-Founder

They had changed the pricing plans and removed the free plan, so if you are starting, it's not free anymore.

IT Specialist

The opening price is pretty high for an account with any sort of features, which makes it tough to justify using their service for a small project.

53% of reviewers feel negative about Mailgun’s pricing. Some users report the cost structure is complex, with fees that add up quickly as volume increases, making budgeting difficult. Reviewers indicate the entry price for advanced features is high, and some essential functions are now behind paywalls. They say dedicated IP addresses and premium tiers are expensive compared to alternatives, which can be a barrier for small projects or organizations with limited budgets. Users think recent changes to the free plan and unexpected charges have caused frustration and made the service less accessible.

Users think Mailgun’s scalability and flexibility make it suitable for organizations needing consistent, large-scale email communications.

DevOPS

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.

Software Engineer

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.

Manager

Need your own custom domain which is understandable for the sake of potential email spam which degrades the credibility of the platform.

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.

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.

Ability to send out email blasts to clients on the regular basis instead of one at a time.

Managing Partner

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.

Peer support specialist, drug and alcohol counselor

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

As a QA, I need to perform different validations related to email sending with Mailgun, and this is really easy to do, even though it was my first time using this type of platform.

Their automated system falsely flagged my SaaS, disabling all transactional emails without warning.

It’s best suited when you’re already committed to building custom email workflows rather than relying on a “set‑and‑forget” solution.

I didn't like how mailgun disable our account (with over 25 active applications/domains and hundreds of users) and didn't tell use why for over 3 days.

Mailgun is a powerful email delivery service that excels in reliability and ease of integration, particularly with platforms like WordPress.

I'm more than satisfied with mailgun as platform, I've used easily a dozen, and It's the one I've stayed with to integrate with software or other platfors for sure.

I’ve been impressed by how much functionality is included in the basic plan, offering features like tracking and analytics that are often premium in other services.

Customer marketing success manager

Have been using mailgun for almost 3 years and has helped solve a very common Wordpress SMTP problem of email delivery.

Owner

If you want to have a reliable email sending and receiving platform then Mailgun does the job.

This caused immediate chaos for my SaaS, as transactional emails are mission-critical.

Technical Support Engineer

I'm part of an internal technical support branch that helps team members with mail delivery inquiries and other requirements.

It took 24 hours for customer support to respond and tell us there was a security problem with our account, but we were left on our own to figure out what was going on and how to solve it.

Developer

Very easy to use, and allows me to provide login verification, password retrieval, etc for the users of the site.

Engineer

Pricing can increase rapidly once you exceed small volumes or require advanced features.

It can be confusing to set up the sending domains correctly when you don’t have much knowledge about how it works.

It’s not free, and costs can add up as volume grows.

Head of Customer Experience and Digital

It is a simple and cost effective option for reducing the rate in which emails end up in junk

Historically, the shared IPs has sometimes been blacklisted (was quite a while since last).

I’ve also seen occasional minor UI slowdowns.

Application Support Engineer

We noticed that some of them are not available in the documentation.

Often it defaults to the US server which can cause confusion when trying to find something.

Founder/Owner

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

Overall performance of the tool when searching for messages sent by our internal software solutions.

For anyone looking for a no-fuss email solution with great value in its entry-level plan, Mailgun is a fantastic option.

Marketing and Digital Projects

More visibility on automated changes (such as automatic suppressions)

Marketing Director

I use mailgun as mail services for a few cuatomers that use High Level

I had a great overall experience with Mailgun, but the dashboard analytics could use some improvement.

Lead Engineer and General Manager

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.

Some settings are difficult to find, making configuration a bit frustrating at times.

Some of the user and account management interfaces were a big challenging to use and navigate.

Fullstack web developer

I have never used an easier to setup and higher quality service.

I use Mailgun with High Level And the best part is the easy way to sync them both

It is a developer-friendly API & solid documentation.

Delivery is affected and is no solution to use.

Easy to use API allows for addition of email functionality in all of our apps.

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.

Some reviewers find Mailgun’s entry-level and free plans generous, with useful features like tracking, analytics, and webhooks included without extra cost. They appreciate the pay-as-you-go pricing model, which allows them to pay based on actual usage rather than fixed fees, and say this flexibility is valuable for keeping costs low, especially for small projects or organizations. Some users report that Mailgun offers more features in its basic plan compared to competitors, and they feel the service is affordable and reliable for their needs. Reviewers indicate that the free tier was previously a strong selling point, serving small organizations well and making Mailgun attractive for those starting out or with low email volumes.

However, some users say that Mailgun’s pricing can quickly become complex and unpredictable, with costs adding up due to per-send, per-recipient, and extra feature fees. They feel the removal or reduction of the free plan and the introduction of paywalls for previously free features have diminished its value for money. Some reviewers report that the entry price for advanced features is high compared to alternatives, and dedicated IP addresses are seen as prohibitively expensive. Users think the overall cost can be a barrier, especially as email volume grows or when comparing Mailgun to other providers with lower prices or more transparent pricing structures.
