Soporte Industrial Automation Used the software for: 6-12 months ### "Una muy buena opcion para enviar campañas de email marketing" December 18, 2022 5.0 Mi experiencia con Mailgun es muy buena la uso a diario en un blog en Ghost Pros Lo que más me gusta de Mailgun es que cuenta con muchas integraciones con herramientas como por ejemplo Ghost, por medio de API. Cons En general la plataforma es muy buena, pero si tengo que mencionar algo a mejorar serían las tarifas, ya que tiene dos tarifas de precio diferentes.

And Mailgun came as one of the favourites and also they had a good free plan. Moreover, it has integration with a mail plugin that I was using. So it seemed a good idea to try it. I'm using it for almost 2 years and it was easy to setup and it's working great since then without any need to fix or change anything. Pros You can try Mailgun and really use it on your site for free Great customer support that will treat you well even if you're using free plan and don't know nothing about emails. Being one of the most popular company, there is lots of information around the web on how-to-dos. Easy integration with wordpress plugins. Cons If you don't have a dedicated IP, your reputation will be influenced by other users. So if someone is using Mailgun abusively and is using the same IP to send emails you may get some problems. Switched from [Zoho Mail](https://www.capterra.com/p/174694/Zoho-Mail/) I was using Zoho mail for transactional emails, which wasn't for what it was made for. Review Source Catalin P. Full-stack Developer Computer Software Used the software for: Less than 6 months ### "Paying for something I can't use (the worst experience)" November 24, 2023 1.0 Horrible. Pros I'd love to be able to fill this section, but I pay for a plan I can't use. Hence, I couldn't try it. Cons I never thought I'll come across such an appaling product and customer service. I pay $35/month for the "Foundation" plan, which includes 50k emails/month. However, my account is limited and can only send email to 9 recipients per email. I provided all the information they asked for, and my account still stays limited. Even more, I have 3-5 days of sending emails, which they keep asking about. So bottom line, I pay money for something I can't use. Now, you might ask - why don't I move on and use something else? Unfortunately, I can't because the Ghost blogging platform only works with Mailgun for sending bulk emails. Conclusion? I highly highly higly advise anyone to avoid Mailgun and use something else if possible. Reason for choosing Mailgun Because the Ghost blogging platform only works with Mailgun.

I wanted to use them because they are a cheaper alternative to use on a WordPress site. Cons I had some issues with the initial setup and the support team was not that supportive. I quickly disregarded this software as I didn't want to waste much time. It was already a week and the slow responses from support didn't help. Maybe I got impatient and switched too quickly. The software looks good, it's just that I needed to implement something quicker Alternatives considered [MailerLite](https://www.capterra.com/p/136603/MailerLite/)[Klaviyo](https://www.capterra.com/p/156699/Klaviyo/) Review Source JS John S. Admin Lead Religious Institutions Used the software for: 6-12 months ### "Powerful e-mail API" August 7, 2023 5.0 Pros Mailgun's API seamlessly integrates with our relationship management software, allowing us to automate communication, reduce workload, and increase impact. Cons We use some of Mailgun's more basic features, and the pricing is a little bit steeper than what we'd like to pay. However, we have still benefitted from the service. Review Source LT Lee T. Founder Information Technology and Services Used the software for: 2+ years ### "Support is SLOW and New Owners have driven down the quality of experience" March 4, 2022 2.0 It used to be fine but going to hell-in-a-handbasket. We will be moving to AWS SES most likely before the month is out. Pros Simple to use for monitoring send activity logs as well as spot complaints. Cons Support is terribly unresponsive. They have been recently purchased and the new folks have instituted what appears to be automated "features" that throttle emails even when you are not exceeding paid limits. Review Source VR Verified Reviewer marketing automation specialist Information Technology and Services Used the software for: 1-2 years ### "Very user friendly and highly recommended" April 7, 2021 4.0 The process from the very start was very straightforward and allowed myself and fellow marketing and development team members to grasp the intricacies and entire tool set within the platform. Pros The ability to connect to our internal platform to send transactional email and monitor activity are features that really stand out and directly address our needs in terms of email deliverability, activity tracking and technical solutions. Cons The ability to migrate from the legacy to the newest version of the platform has not been the simplest process. While the workarounds have suited our needs just fine, it hasn't been the simplest process to migrate over from the legacy version.

All in all it's the best! Cons Mailgun didn't notify me when my account was suspended for a verification and in that time I lost many emails that may have resulted in contracts if they were delivered! You need to check you account regularly to make sure everything is OK! Review Source Brian C. Partner Internet Used the software for: 1-2 years ### "Great service with easy integration." September 5, 2019 5.0 First 10k emails through Mailgun are free, why not give it a try. Transactional outbound emails originating from Mailgun and are less likely to be blocked as spam. Pros Free options for small/startup businesses with reasonable prices for larger companies/projects. Mailing lists included. WordPress integration is quite simple with the Mailgun plugin. Once installed and configured, the WP plugin allows websites to send form email responses with relative ease. The mailing list feature is nice bonus. Management portal was updated recently and vastly improved the UI/UX experience. Cons Extended log access is only available in more expensive plans. Review Source JP Jon P. Systems Engineer Automotive Used the software for: 2+ years ### "Mailgun provides reliable email delivery and tracking software" April 29, 2019 5.0 We use Mailgun to send emails from multiple domains through our ERP system. Mailgun as given us noticeable improvement to our email metrics and tracking. I would recommend Mailgun to others. Pros Our ERP system added integration with Mailgun several years ago and our ability to track and verify emails had been delivered significantly increased. We noticed an immediate increase in our email delivered confirmations. This is significant for us as we send our monthly account billing statements through email. If our emails aren't delivered, we don't get paid. Mailgun also provided much superior email tracking so we can identify which emails weren't delivered and find another way to get in contact with our customer. Cons Our biggest limitation with Mailgun is with our ERP system and how they only chose to provided limited support to the many features Mailgun offers. Review Source Michael H. Co-Founder | Creative Director Marketing and Advertising Used the software for: 1-2 years ### "Robust SMTP API for your sites, with no comprimises" April 27, 2019 5.0 We use Mailgun alongside other services such as Mandrill and SendGrid, depending on our clients needs for their site/app. Pros Mailgun has a really easy to implement API (for devs) with a bunch of different languages support like curl, PHP, Java, etc. - Within minutes, we were running the PHP API on our app, and sending out transactional emails. Also good for devs: the extremely in-depth official docs provided by Mailgun. Along with case examples, and demos, you'll be ready to go, even if you're a bit less experienced with implementing an API of this sort. One of my favourite features is the email validation API, which easily integrates into your forms via jQuery, and uses the Mailgun API to validate email inputs as users type their email. We use it on all of our forms now! Cons It's worth noting that everything that operates through Mailgun is through API, unlike something like SendGrid which offers a full dashboard alongside their API. This may or may not be an issue for some people. Review Source Héctor A. CEO / Lead Architect Information Technology and Services Used the software for: 2+ years ### "Need email notification support? This is the one" November 4, 2018 5.0 Is easy to use, has great support and customer care is THE option for email notifications in your App/WebApp. Pros Easy to use! Supports integration with a lot of languages including PHP and Rails, we were able to use it in no time, They provide you with free mails monthly for when your startup is starting and is blazing fast, much better than connecting the app to a conventional email. Cons Nothing at all, hoping they can implement PWA notifications soon. Review Source JM Jessica M. IT Manager and Client Success Partner Information Technology and Services Used the software for: 1-2 years ### "Exceptional email software. You must try!" April 23, 2023 4.0 Pros The ability to connect to our internal system to send transactional emails and monitor activity are genuinely exceptional features that fully meet our criteria for email delivery, activity tracking, and technological solutions. Cons I have many complaints that come from not understanding the technical aspects of the software, which are too difficult for me to comprehend. I am unable to give a thorough opinion on the advantages and disadvantages of using the software or its user interface. Review Source GB Goma B. Instructor Non-Profit Organization Management Used the software for: 6-12 months ### "A Reliable Email Service Provider for Businesses" April 30, 2023 5.0 Pros One of the biggest pros of using Mailgun is its reliability. I have rarely experienced downtime, and the emails are always timely. It also offers an API that integrates seamlessly with different software applications. I can easily integrate Mailgun into my website, CRM, or marketing automation software to send transactional and marketing emails without any hassle. Cons One of the cons of using Mailgun is its pricing model. The service charges based on the number of emails sent, which can be costly for businesses that send a high volume of emails. Another suggestion for Mailgun is to provide more comprehensive documentation for users who are not familiar with API integrations. Review Source YA Yuri A. Help Desk Manager Information Technology and Services Used the software for: 2+ years ### "A solid service" September 1, 2023 5.0 Pros I like the way the dashboard is built, it's really easy to use. Easy to find e-mails. Cons I always struggle to find the function of whitelisting an e-mail, but I always get there eventually. Review Source AH Albert H. Developer Non-Profit Organization Management Used the software for: 6-12 months ### "Easy to use, very intuitive" December 22, 2023 4.0 Pros Used this to track email delivery and perform transactional emails. Works as advertised Cons There is a learning curve to use this service Review Source Ivan C. Founder and Director of Business Development Used the software for: 6-12 months ### "One of the best email marketing solutions price wise" January 18, 2018 5.0 We send email marketing to our user base through Mailgun, monitor results, and save money when compared to other solutions that are more manual.. Pros We use Mailgun to send to large email marketing lists because it's more affordable than many alternatives. The UX is pretty solid and the reporting tools are nice. Cons Sometimes there are things in the report that don't make sense like an open rate dropping considerably one day and then back to normal. We can't really tell what caused that. Also the open rate is lower than other tools that are not marketing based. So perhaps they're tagged as marketing server. Not sure there's any way around that and they take email server health seriously Review Source VR Verified Reviewer Senior Software Engineer Computer Software Used the software for: 2+ years ### "Reliable base for emailing in a product" September 3, 2019 4.0 Pros We liked the simplicity and set it and forget it nature of the product. We never really ever had to go in and perform maintenance since when we first set up the service on our app a few years back. Cons We recently had an issue of emails not getting sent out that was due to a different service we had integrated with mailgun. Because of this issue, we had wondered if we were able to go back in the mailgun logs to see the old emails. Unfortunately, the logs only go back to about 2 months or so which meant we had just lost all the old data. It would have been nice if there was some option to perform automated backups of everything or automated exports after the 2 months period. Review Source FK Fotios K. Customer Support Team Lead Computer Software Used the software for: 2+ years ### "Mailgun is pretty good" January 4, 2023 5.0 Overall Mailgun is a great tool and I highly recommend it. Pros I like how it literally has every piece of information that you need to make an educated decision about potential client accounts and wether they are fraudulent or not. Cons It's kind of complicated to understand and get acquainted with at first. Review Source JW James W. Software Engineer Information Services Used the software for: 1-2 years ### "Simple pay as you go transactional email" November 25, 2022 5.0 Pros \- Being able to pay based on my usage not a fixed price- Easy to use and well documented API- Webhooks to handle events such as bounces and unsubscribes Cons \- Initially I had some deliverability issues but support were very helpful in resolving them- Slightly more expensive than some competitors but you get more features for that Alternatives considered [Amazon SES](https://www.capterra.com/p/179662/Amazon-SES/)[SendGrid](https://www.capterra.com/p/204113/SendGrid/)[Postmark](https://www.capterra.com/p/254711/Postmark/)[Mailchimp](https://www.capterra.com/p/110228/MailChimp/) Reason for choosing Mailgun Cheaper than most and easier to set up than SES. Review Source VR Verified Reviewer Product Manager Education Management Used the software for: 2+ years ### "Good software, but UI and delivery issues" December 8, 2019 4.0 We use Mailgun to send automated emails for people who are registering on our site and to reset passwords. Pros Mailgun is an easy platform to automate sending mail. It is really nice that you can set up alias emails so that you don't have to share a personal email on a platform, but you also don't have to set up a new email account. Mailgun did recently update the UI of the site, so it is more modern, but it could still be improved. Cons Some of the UI is still a little counter-intuitive. Unlike MailChimp, there is also not the easy interface to customize messages. We have a number of issues with the emails from Mailchimp going to spam and users struggling to find them. Review Source VR Verified Reviewer Web Developer Used the software for: 2+ years ### "good for Transactional email and more" March 12, 2018 5.0 Pros Mailgun's system is set up so well, and their SDKs for different languages are so complete, that these days I add a domain, add a Ruby gem, and my new Rails project has transnational email ready to go, highly deliverable, and I just don't worry about it after that. It just works. Review Source TM Tyler M. Senior Marketing Manager Marketing and Advertising Used the software for: 2+ years ### "Great SMTP for sending bulk or transactional email" June 16, 2020 5.0 We have achieved great eCPM mailing costs and gained access to higher volume mail to reach our subscribers Pros Mailgun allows for a lot of customization. Users use the service on the backend as the infrustructure to mail, while using their own service portal to send the mail and segment their subscriber base. Mail sending is fast, reliable, and they have dedicated and shared IPs for sending. Cons Since it is only to be used as the infrastructure to mail, companies will need the know-how of hooking up SMTP connections and have access to a developer and front-end software. Reason for choosing Mailgun We use Mailgun in sublement to other SMTP and ESPs but it very well could function on its own. Review Source Christopher C. Marketing Photography Used the software for: 6-12 months ### "Most reliable yet" November 21, 2019 5.0 Pros We've used a lot of solutions, we're a mid-sized business and don't send enough for our own IP, however, every other provider has not had great delivery due to that. Mailgun has been the first shared-IP provider to give us unbeatable performance. Cons Not being able to schedule emails more than 3-days in advance is a little bit of a downer, however, workarounds are simple. Alternatives considered [SendGrid](https://www.capterra.com/p/204113/SendGrid/) Review Source VR Verified Reviewer Reporting & Analytics Manager Information Services Used the software for: 1-2 years ### "Excellent mail log makes tracking mail activity simple" September 24, 2018 4.0 We run software that includes both manually sent as well as automated email. Inevitably, users will either not receive or claim that they did not receive an email. This quickly helps alleviate those issues and show proof of delivery with timestamp. Pros I don't have a ton to benchmark Mailgun against but it's made my job much easier when needing to track our outgoing email. At it's simplest, I can quickly search for failed email messages or confirm that email was sent and received along with the content of the email. Cons There may be a way to filter or create saved filters that I'm not aware of, but I've been restricted to searching either by an email address or by an event type (ie Accepted, Delivered, Rejected, etc.) I do sometimes have to search for a bit to find what I'm looking for.
