Incredible Deliverability, Clean Platform, Success with MailGun!

Pros:

Clean UXI for navigating the system, simple set up, clear dashboard to find issues quickly and navigate around the site. Ability to clean database lists to minimize bounce. However, the BEST part is they are free up to 10,000 emails a month, which is a ton! So to give the full custom power of connecting your domain and sending out, that's a huge value. I will get over that limit and upgrade soon, but that is an incredible way to start a relationship. Almost a year of free service to use their system versus my server.

Cons:

I actually have not found anything that I do not like. Many will complain about high bounce rates or going into spam. I find that issue arrises on multiple factors outside of mailgun control, such as the receiving server, and the mail habits of the person opening it, do they get a bunch of spammy mail already? And was the mail piece written in a poor nature, this increases spam folder direction, however, they do have dedicated IP service for those wanting to mitigate one area of cause for spam direction. Again, never been my experience.

Reasons for choosing Mailgun

Again, the main required integration for our CRM, and that is perfectly fine with us because it is smooth operating on the free account, I'm sure will be great on dedicated IP account.

Reasons for switching to Mailgun

Utilizing a new software CRM integration, they favored MailGun so I gave it a shot and migrated over, happy I did, everything is incredibly smooth.

Mailgun just does what I claims to do

Mailgun is a powerful email delivery service that excels in reliability and ease of integration, particularly with platforms like WordPress. It’s straightforward to set up and handles email delivery with minimal maintenance. 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.

Pros:

Mailgun is one of those tools that simply works. As someone who uses it regularly, I appreciate its reliability and ease of integration, especially with WordPress. Setting it up is straightforward, and once configured, it takes care of email delivery without needing constant attention or troubleshooting. One of the standout aspects is how much you get with the basic plan. Features like email tracking, analytics, and solid deliverability are included, which is often more than enough for smaller projects or businesses. It’s refreshing to see such a feature-rich offering without having to upgrade right away. I also love how well Mailgun handles what it promises—emails are delivered quickly and consistently, which is crucial for ensuring important communication doesn’t end up in spam folders. You also have a pretty good overall statistic. For anyone looking for a no-fuss email solution with great value in its entry-level plan, Mailgun is a fantastic option.

Cons:

Some settings are difficult to find, making configuration a bit frustrating at times. Additionally, the service region selection defaults back to the US, which I always forget to change. These minor inconveniences don’t overshadow its overall performance, but they’re worth noting for users who value a seamless experience. A more intuitive settings layout and a persistent region selection would make Mailgun even better.

Reasons for choosing Mailgun

When deciding between Mailgun and Postmark, the key factor for me was pricing. Mailgun’s basic plan offered more value for money, with features like email tracking, analytics, and solid email deliverability included right from the start. While Postmark focuses heavily on transactional emails, its pricing felt less competitive for the range of features Mailgun provided. Mailgun seemed to be the better option. In the end, the combination of affordability and functionality made Mailgun the obvious choice for my needs.

Don't use mailgun. You'll lose all you emails, customers and they don't confirm to EU compliance law

We're a paying mailgun customer for over 10 years. Until mails stopped going out. After logging in, there was an error that says 'account disabled' with no further information. 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. All in all it took over a week to get our accounts back. By that time, we had migrated away to better, cheaper and more reliable alternatives.

Fantastic - Need improvement on the dashboard side + Certification required

I had a great overall experience with Mailgun, but the dashboard analytics could use some improvement. Additionally, MailGun could also offer us more insights regarding the missing emails, bounces, etc.

A user friendly and efficient tool for email testing

My experience with Mailgun has been very positive. 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. Its user-friendly interface was very helpful to me.

What I liked most about Mailgun is how easy it is to use and set up. The interface is intuitive, and the email tracking and validation features make testing and troubleshooting very straightforward. It’s a great tool for QA work and for ensuring that emails are being sent and received correctly.

Cons:

What I liked least about Mailgun is that some advanced settings and logs are not immediately visible or easy to find across different domains. It takes a bit of navigation to locate specific details when troubleshooting.

Mailgun makes sending and tracking email for applications easy. The API and SDKs are straightforward, webhooks are reliable, logs are clear, and deliverability is strong. Integration, testing, and scaling are painless.

Cons:

It’s not free, and costs can add up as volume grows. Some advanced features sit behind higher-priced tiers, and pricing for dedicated IPs or email validation can be confusing. I’ve also seen occasional minor UI slowdowns.
