December 24, 2024 3.0 It is a decent experience; it meets basic email needs effectively. Pros Reliable email delivery with good tracking tools. Cons The interface can feel complex for beginners. Review Source CM Colin M. Director Computer Hardware Used the software for: Less than 6 months ### "First use of Mail Gun" January 29, 2025 5.0 Very positive.

I use it for automating mail messages from my astroimaging set up. Cons Nothing - was simple to set up. I had one problem which was easily solved by support. Review Source JC Jaime C. CEO Management Consulting Used the software for: 6-12 months ### "La opinión de un mexicano" August 31, 2024 5.0 En la actualidad, con tanta tecnología de bajo código, contratar , no hace mucho sentido, además Mailgun, requiere una plataforma de lanzamiento, yo nunca pude enlazarla a Bibble.io lo que hice muy rápido con Sendgrid y ocupo un plan gratuito, envío 3,000 mails al día, Pros Cuando por fin pude hacerlo funcionar, su eficiencia es muy grande, debo reconocer que su potencia es muy buena Cons Ya lo diré más adelante, pero el soporte me parecía lento y malo, le falta mucha documentación para implementarse Review Source Brandon M. Creative Strategist Marketing and Advertising Used the software for: 6-12 months ### "Incredible Deliverability, Clean Platform, Success with MailGun!" December 10, 2019 5.0 Super pleasant, great chat support, fast email support replies, always quick to help and communicate. 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 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.

Switched from [SendGrid](https://www.capterra.com/p/204113/SendGrid/) Utilizing a new software CRM integration, they favored so I gave it a shot and migrated over, happy I did, everything is incredibly smooth. Review Source Lucas P. Creative Director Information Technology and Services Used the software for: 2+ years ### "Bare-bones but super reliable and easy to use." April 26, 2020 5.0 I use several different email service providers, each for a different reason. I use almost exclusively for inbound mail processing. The inbound processing also offers a preliminary spam filter so that at least most of the spam isn't sent further down my process chain. It's super easy to set up inbound routes using specific strings or wildcard matches that will accept mail and forward to multiple different recipients. These recipients can be either proper email addresses or webhook endpoints. I often use the address forwarders in combination with the SMTP outbound service to build a system where Gmail users can use their free gmail.com account to receive and send emails from their small business domain without having to sign up for and configure a proper G Suite account. I use the webhook forwarders in combination with Zapier and Integromat to receive any emails that need to be processed and automatically acted on. Mailgun normalizes all the different types of email and attachment encodings and packages the message data into an easy-to-parse JSON package that makes it super easy for me to grab what I need and reliably act on the normalized data. Pros Inbound mail processing with spam filter Free tier offers great sending limit SMTP and API integration for outbound messaging Cons This product doesn't offer any sort of backend mail building or sending functionality. It's only an engine for sending messages. This means you'll have to build your messages somewhere else and integrate them into your sending code. Alternatives considered [Mailchimp](https://www.capterra.com/p/110228/MailChimp/) Reason for choosing Mailgun The pricing structure for was a much better fit for my specific needs of inbound mail processing. Mandrill provides inbound mail as part of a much larger and more complete service offering that was not necessary for my use case. I simply wanted a service that would accept, process, and forward messages without all the other tools built into Mandrill. Review Source Arkadiusz K. IT Project Manager Information Technology and Services Used the software for: 2+ years ### "High Deliverability" December 1, 2023 5.0 Pros A clean interface is a plus, but functionality is still limited compared to Mandrill. However, the core functionality—transactional emails—works very well and seamlessly. Cons Very basic interface and limited options compare to competition. Switched from [Mailchimp](https://www.capterra.com/p/110228/MailChimp/) Pricing pay-as-you-go was not availble in Mandrill/Mailchimp. Review Source Efezino U. Managing Director & Software Developer Transportation/Trucking/Railroad Used the software for: 6-12 months ### "Easy Integration and Value for your money" December 9, 2022 5.0 is a powerful and effective email service that can help businesses and organizations streamline their email communications.

The intuitive user interface and comprehensive documentation make it simple to get started with Mailgun.Scalability: Mailgun is designed to handle high volumes of email traffic, making it a good choice for organizations that need to send a large number of emails on a regular basis.

So I did. I created the account on Mailgun, ran a couple of tests, got familiarized with the API, and developed a standard operating process around it, took me 1 week.Everything went well in the testing phase.After sending my first batch of emails LIVE (oh the timing) I got my account temporarily disabled. I get to fill in a completely irrelevant form that was supposed to confirm the "legitimacy" of my business. My business is 100% legit. I got my account permanently suspended, because why not, and who cares? It is not illegal in any country to send cold emails. I haven't received any explanation, there was no warning before starting to use the app. Waste of time and money. Pros Yes, there are not too many things left to like at the end of the day. Cons Takes a lot of time to set up and requires a serious time investment compared to its competitors.Docs are messy and outdated/inaccurate.Extorsion tactics.They disable your account for no reason.There is no support.

Marketing Manager Marketing and Advertising Used the software for: 2+ years ### "Helps you land into prospect's inbox" February 24, 2023 5.0 is a comprehensive email marketing service that provides businesses with the tools they need to create effective email campaigns and ensure deliverability. Its advanced features make it a popular choice for businesses of all sizes looking to improve their email marketing efforts. Pros The DMARC record validation and domain verification process is so smooth and generous that it increases your chance of landing in your prospect's inbox by almost 100%. Cons The pricing is higher than any other competitor products. Alternatives considered [SendGrid](https://www.capterra.com/p/204113/SendGrid/) Reason for choosing Mailgun Higher rate of mail deliverability to the inbox Switched from [SendGrid](https://www.capterra.com/p/204113/SendGrid/) to try out new features and increase the deliverability.

MD Information Technology and Services Used the software for: 2+ years ### "Excellent, powerful service" May 21, 2023 5.0 Pros Different SMTP users (not able to log in - if someone was to compromise a system and get the SMTP user details) Cons SMTP user passwords are auto generated, which in 9 out of 10 cases is fine, however some routers don’t allow an SMTP user password this long. Switched from [SMTP2GO](https://www.capterra.com/p/166646/SMTP2GO/) More features - however, we still use SMTP2GO due to password length issues. Review Source Norbu M.

Managing Director Computer Software Used the software for: 1-2 years ### "Best for transactional email and accurate email delivery." September 18, 2022 4.0 Best for overall email solution, You won't regret paying. Pros We've been using since few years and it's one of our most used and essential software for out business. It seamlessly integrate with any system and provides fast and accurate email delivery solution. Since we've been using mailgun it's very rare that email sent from our system goes to spam folder. Also, with their dedicated IP option email delivery and white listing is even more easier. Cons email tracking feature is not that accurate and also I personally found and reported bugs into the system UX.

When you're trying to reach out to the support, they close our tickets without even answering, ghosting. Absolutely WORST product ever used and support team faced, it's absolutely garbage.

Pros Very reliable service for a good price. We use for transactional emails for sales lead captures, dispatched via API. Solid and reliable. Cons No concerns, long time user. We probably have some ancient price, so I cannot comment on that. Switched from [SendGrid](https://www.capterra.com/p/204113/SendGrid/) To be fair we use both, in different cases, and are happy with both. If you are considering both, I don't think there's a wrong answer here.

However, the ease of implementation and support by different plugins and software make it a really good tool. DNS is easy to configure so we have no issue with deliverability. The dashboard is also great and offers good logs and graphs. Pros Great documentation, 10k emails on the free plan was great previously for the prepaid plan is okay. Good API and interface. Cons Downtimes and deliverability issues can be daunting.

When things go wrong, there is enough information to find the cause. Pros Ease of setup. Transparent pricing. Free tier goes up until a really high scale.

There are no alarms in place for when something starts going wrong unexpectedly. Switched from [Mailchimp](https://www.capterra.com/p/110228/MailChimp/) Mandrill changed policies, and at the time the cost/benefit ratio of staying there was not good. Review Source TT Todor T.

Cheaper than most competitors Cons You can not search the logs with the email content Review Source Elliott L. Developer Computer Software Used the software for: 2+ years ### "Great solution for mail sending from vps providers like AWS" July 18, 2019 5.0 We use for all of our email sending needs across multiple servers and products. We implement mailgun as the default mail sender for any new projects too. Pros Its api is very simple to use, most PHP frameworks come with integration out of the box - if they don't, mailgun supports standard smtp anyway. Great usage graphs and multiple regions to send from. Is makes it very easy to send emails from php applications which would normally be blacklisted if you use standard php mail from inside a VPS on e.g amazon/azure/vultr/digitalocean. Very generous free tier. Cons Their anti spam measures can sometimes not work - if your sending details have been compromised you can be hit with a pretty large bill before you realize someone has been sending hundreds of thousands of emails on your behalf.

Their analysis helped us understand our target sample, which enabled us to coordinate campaigns better. Pros 's many features make email marketing easy to plan and implement. We can import contacts and create target group lists. Mailgun's custom templates allow you to design unique campaigns and save them as drafts. It's incredible how the real-time notifications and statistics show how actively customers engage in the campaign. My team and I love that future campaigns can use the same model. It's also good that you can hide and reorganize dashboard items. Cons I have no major technical problems. improves email workflows for organizations large and small, the creators of Mailgun provide various videos and how-to materials that help develop our skills, and the support staff is always available.

Pros The best would be their free tier, they recently changed their free tier but you still get free 1k+ emails per month. This is thier "pay as you use" tier. Very usefull if you're still new as you get all the features of a paid service. Very cheap even when you exceed the free emails. Cons I wish they have a lower tiered plan like $5 or $10 a month for low traffic sites. As a developer not all sites needs 10k emails a month.
