"Great Spam Checks, But the Pricing Didn’t Fit Our Usage"

2/5

What do you like best about Mailgun?

The UX of the Mailgun platform is really easy to pick up, even with very little training. The account setup process was quick and straightforward, and within 24 hours we were up and running. Our primary use of the platform was to perform spam checks on our email templates before we sent them out. The tests were quick and efficient and the overall performance of the platform as good as you would expect. Review collected by and hosted on G2.com.

What do you dislike about Mailgun?

The system itself worked great, our main issue with the platform was to do with the pricing structure. For what we wanted to do and the number of tests we were doing each month it was far more expensive than competitors. Review collected by and hosted on G2.com.

What problems is Mailgun solving and how is that benefiting you?

We needed a way to be able to test a wide range of different email templates and newsletter content for any spam flags. Mailgun allowed us to semi-automate this process and give our marketing team a clear view about which emails would potentially be seen as having a higher spam score across a wide range of different email clients Review collected by and hosted on G2.com.

I had an issue to send emails to google user in my own email provider after updating my domain config, maybe the configuration could be improved, it is something like my emails are not longer with a right signature Review collected by and hosted on G2.com.

"Reliable and Easy-to-Use Email Delivery Platform"

5/5

What do you like best about Mailgun?

Mailgun is a reliable email delivery platform that makes it easy to send both transactional and marketing emails. I appreciate its developer-friendly features, straightforward integration, and the helpful analytics that let me track email performance. Overall, it feels like a solid option for businesses that need dependable email delivery along with clear monitoring and visibility. Review collected by and hosted on G2.com.

What do you dislike about Mailgun?

What I dislike about Mailgun is that some of its more advanced features and settings can take a while to understand, especially for new users. The pricing can also feel a bit complicated, depending on the volume of emails being sent. Review collected by and hosted on G2.com.

What problems is Mailgun solving and how is that benefiting you?

Mailgun helps me tackle the challenge of sending emails reliably while also keeping track of delivery performance.

"Effortless Email Delivery, Limited Data Retention"

3/5

What do you like best about Mailgun?

Mailgun saves us the hassle of dealing with email servers and the minutia of email distribution. I like that it retries temporary failures, suppresses addresses that are known to fail, and provides delivery, open, and click metrics that we can show our clients. Review collected by and hosted on G2.com.

What do you dislike about Mailgun?

I find Mailgun's log retention limited to 30 days, so I can't get much historical data; it would be good to have at least a year's worth. We've had issues with our domains being blocked, and it would help to get a warning before that happens. I've also heard from other departments that billing can be hard to understand. I wasn't involved in setup, but I know it took a bit of development effort, though I don't know how extensive. Review collected by and hosted on G2.com.

The dashboard could be more intuitive, especially when I’m troubleshooting delivery issues or managing multiple domains at once. Review collected by and hosted on G2.com.

"Effortless Email Automation with Top-Notch Deliverability"

4/5

What do you like best about Mailgun?

I use Mailgun for all our automated reports, welcome invites to users, and even password reset emails. What I like most about Mailgun is its simplicity. Their deliverability is incredible, especially when compared to our other more marketing-based email system. The initial setup was very easy and it's built for easy development. Mailgun handles all of these emails for us, so we don't have to manually manage them. The logs are also incredibly well done, making it easy to go back and find any issues with why emails aren’t being sent. Review collected by and hosted on G2.com.

What do you dislike about Mailgun?

Not much. I'm being nitpicky here, but when you're on a large monitor, and you want to add filters to your logs that you're looking through, because the filters show on the far right, it's just a little weird to me. Like I look at the left, click the filter button, to have them show on the right. Not that bad, like I said, being nitpicky Review collected by and hosted on G2.com.
