Transactional emails are emails triggered by a user's actions within an application or website. They help you maintain your customer relationship by confirming you’ve received their request or are responding to their action. Some examples of transactional emails are: - Password reset emails - Abandoned cart emails - Order confirmation emails - Welcome emails - Email receipts These are just a few of the different types of transactional emails, but the core of transactional messages is that they’re action-triggered. They rely on email automation rather than being sent by a real person in real-time. Whether or not you plan to create dozens of email campaigns or set up simple notification emails, transactional emails are just one component of your overall email program and customer experience.

BW Benjamin W. Lead Engineer and General Manager Internet ### "Mailgun is still best in mass email delivery" 5.0 Overall Rating 5.0 5.0 Ease of Use 5.0 5.0 Features 5.0 5.0 Customer Service 5.0 5.0 Likelihood to Recommend 10/10 April 24, 2026 Our experience continues to be fantastic, and we continue to recommend Mailgun to clients who need SMTP services. Pricing is still very affordable, and service beats competitors that we're recommending clients migrate to Mailgun from. Pros Mailgun was very affordable to get started (they have a free tier) and are scaling well with over 20 active clients using our account for SMTP. Cons We haven't experienced any downsides or complications that were due to Mailgun. Clients don't complain about it, so we're content. Switched from [Gmail](https://www.capterra.com/p/202338/Gmail/) Gmail was not a good option for bulk emails across many clients and websites. It was more costly, harder to manage, and just not designed for this purpose.

Actually more than great. Spectacular. I have never used an easier to setup and higher quality service. Pros It’s ever easy to setup and good pricing. I have never ever encountered an issue. It’s as good as it gets. Cons Nothing honestly it’s great. I have never encountered anything that made me look for another alternative.

The learning curve is pretty quick if you already understand DNS, Webhooks and APIs but if you don't Mailgun has plenty of instructions. Cons I don't have a dislike - it has worked perfectly. I tried a newer platform and it did not have all features as promoted. MailGun is the original best.

The api is quick to respond, easy to use. Great! Cons Not much negative to say. Historically, the shared IPs has sometimes been blacklisted (was quite a while since last). However, when contacting the support they've quickly taken the out of rotation.

Additionally, MailGun could also offer us more insights regarding the missing emails, bounces, etc. Pros I appreciate its simplicity, reliable delivery, and strong inbox placement, which ensures excellent email results. Cons I believe the math behind the dashboard should be transparent. We noticed that some of them are not available in the documentation. I hope MailGun offers a certification program so I can become certified for this.

HJ Henrik J. Founder, Developer, Systemadministrator Computer Software ### "Thank you for keeping it simple" 5.0 Overall Rating 5.0 5.0 Ease of Use 5.0 5.0 Features 5.0 5.0 Customer Service 5.0 5.0 Likelihood to Recommend 10/10 November 12, 2025 Again, I have nothing but positive words to say about your business. Keep it simple going forward, as you have thus far, and you have one guaranteed customer at least. Pros It is well documented and easy to work with, which, as a developer, means quite a lot. It gives me the options, to keep my mail communication within the EU borders, which is key in my field working with EU businesses. Support has been superb thus far, those few occasions needed. Cons Yet to find any cons. It covers my needs perfectly. I am able to relay mails from self-hosted mail servers, along with using the API for my applications. Literally all I need personally, and these is covered nicely. Switched from [SendGrid](https://www.capterra.com/p/204113/SendGrid/) Couldn't keep our mails within EU borders (at that time at least). Their portal was clumsy. As I recall their API was fine and easy to work with too, but those other pointers made us do the switch.
