Mailgun's world-class tech support and the power-packed features including the smart email templates and email editor caught our attention to switch from our previous application. Review collected by and hosted on G2.com.

Although there is detailed documentation to support the self-implementation of the APIs, it still requires some programming background to in fast troubleshooting Review collected by and hosted on G2.com.

We used to like Mailgun, but not anymore. Over the years, the product has had little to no improvements, and their support has been getting worse.

If you are looking for an API-only solution without dedicated support, you can try it. Review collected by and hosted on G2.com.

We were early adopters (when Rackspace managed Mailgun, and used to have 10,000 free emails/month). Even though we were on a free basic version (sharing IP with others), and if the IP were blacklisted the support would quickly assist in changing to a reputable IP address.

Their dedication and super-fast support made us onboard with a paid plan, as we needed support like this in case something went wrong with the campaign.

The UX wasn't good from the start, even though many people were requesting feature updates(voted features by customers). But, we started noticing that the UI started to break first (still broken 😂), then started to get deliverability issues, and they suggested adding another dedicated IP address (was sending around 1.5M - 4M at the time). We requested 3 additional IP and specifically mentioned to assign clean IP addresses.

They didn't even bother to check and provided IP addresses and 1 was blacklisted by major spams checkers (probably used by some other client of theirs). And when we requested to replace it with another IP address, they sent us a document on how to unlist the IP from blacklist🤦‍♂️.

We decided to remove the IP from Mailgun itself, but they warned us that if in the future if we require another IP then they will assign the same IP to us.

We don't add our new customers to Mailgun anymore. Review collected by and hosted on G2.com.

Set up of Mailgun was reasonably straightforward. Review collected by and hosted on G2.com.

Nothing that dislike about the product. Does the job I need it to do. Review collected by and hosted on G2.com.

Easy to use and reliable. The reporting features are very helpful too. The option for dedicated IP is great for businesses sending lots of emails. The email verification API also helps us protect our domain reputation. Review collected by and hosted on G2.com.

Only one API key. I wish we could generate multiple ones with different access levels so we could easily revoke them if anything goes wrong. I wanted to have one key for email verification only, and one key for each application that uses the email API. Review collected by and hosted on G2.com.

Mailgun helps me verify my email list to ensure valid email addresses. This is important for email deliverability and for ensuring my clients receive the information they need from me. Review collected by and hosted on G2.com.

It can be a little confusing to get Mailgun setup. Fortunately, they provide step-by-step instructions. It would be better if they gave more video instruction for the "how-to". Review collected by and hosted on G2.com.

The ease of use is very good.

The integration with mailster and wordpress allows to have an e-commerce with an effective email marketing strategy. Review collected by and hosted on G2.com.

It seems a bit expensive to me.

Also, if it is not used, the charge is the same, so it is important to have a serious campaign strategy.

I wish I had more economical plans or per-use plans. Review collected by and hosted on G2.com.

Ease to use API, good logs, developer first Review collected by and hosted on G2.com.

Mailgun could've been a cool name. Their service ruins it. Review collected by and hosted on G2.com.

Mailgun was supposed to help boost my business with enhanced email capabilities. It did not. Not at all. I tried to follow their video tutorial to begin to configure my email. It was quite confusing and I wasn't able to follow it very well. The result: I am now unable to send and receive emails for my business! I decided to reach out to Mailgun to get the email reconfigured properly. Come to find out, their "customer service" is an option you HAVE TO PAY FOR. You are supposed to upgrade your basic account just to get a phone number!! I filled out 3 "tickets" asking for help. I received one confusing response from a Mailgun rep which didn't help at all. I then created a fake inquiry to their sales team to get connected to someone. She was not helpful, only interested in sales. I then found a few Mailgun emails online and sent MORE emails to the Mailgun email addresses, but still, no response from Mailgun. I canceled the account to end the madness. Mailgun was a complete waste of time and money for me and my business. Review collected by and hosted on G2.com.

Email deliverability for outgoing transactional email... It just works! Easy step by step wizards to get some of the more tricky configuration things in place, already integrated into the platforms I use as a developer. Review collected by and hosted on G2.com.

I thought hard about whether there was anything I didn't like about Mailgun and honestly couldn't find one. If anything, I'd like there to be a plan between the free and the foundation plan, as some of the paid features would be very useful to experiment with in hobby projects.

Nothing, which is why I'm switching all my clients off of their platform. Constant pain in dealing with them. They keep changing things and you have to deal with it Review collected by and hosted on G2.com.

They don't filter our spam emails. Account got hacked and they exploited this email and sent over 1 million emails within a couple of days - no email alerts from Mailgun on the usage and they didn't block a single email! Of course, they charged me for every single email. These were blatant spam emails too - pills, women, etc. This is not a platform to rely on. Review collected by and hosted on G2.com.
