Mailgun is a transactional email API service which was owned and supported by Rackspace (acquired in 2012) and then spun off in 2017 as an independent and standalone entity. It is now supported by Sinch since that company's acquisition of Mailgun and Mailjet, through acquiring Pathwire.
To be honest, the tools are quite similar and again I dont recommend using them as a standalone products, but they power the work we do via CRMs and our marketing campaigns. Mailgun integrates slightly better which it is why it is the preferred choice for our agency, as it …
We chose Mailgun over sendgrid and Postmark because we really like their API. We have stuck with them because they have never given us any reason to switch. Their reliability is superb and their API remains excellent. sendgrid and Postmark are both good in their own rites, …
They have a great free tier for up to some amount of emails a month. Looks attractive when you are a new startup, but once you have customers and they go down, not so much.
MailGun is more expensive than SparkPost and about the same price-wise as SendGrid. MailGun had a notably easy set-up process, since they are the first SMTP service we signed up with, and their support has been very helpful in identifying deliverability issues, providing …
Amongst the various transactional email vendors (Mandrill by MailChimp, SendGrid's transactional email product, Mailjet, etc.) they are all relatively similar. Mailgun stands out in that it has one of the more generous free tiers and therefore is a strong choice for small …
I chose Mailgun because I work in the healthcare space, and they were the only company I could find that was decent, not over the top expensive, and would sign a BAA.
Not really a con but I typically choose SendGrid over Mailgun simply because I've been using SendGrid for so long. Overall, SendGrid and Mailgun are both rock solid and very affordable. You could probably flip a coin on which one to use. I would definitely look into SendGrid's …
Mailgun was selected by the co-founders and original development team. But once I took over as the head of development and marketing we switched over to the competitor, SendGrid. SendGrid was not only cheaper, but gave us a much more robust product with marketing emails, ads, a …
I've tried SES. It had spotty deliverability and AWS has fiddly docs and apis. I tried a few others and while some worked well, they had neither the exposure or maturity to make me confident in using them in a production app. Out of all the products that I have tried that offer …
I used Mailgun first, and after they weren't able to fix my problems or offer any support I switched to Postmark with lower bounce rates, higher delivery rates with more detailed reporting. Setup is more of a to-do but it's well worth it once you start seeing your bounce rate …
As I mentioned before, even when you do try to validate an email address client side, you have options (see above) BUT and that is the big but, those are mostly a regex solution, but it's not enough. mailgun addresses that exact issue and also looks at the domains, their rules, …
We went with Mailgun because they had fantastic APIs and libraries (Ruby in our case) and because their pricing was among the best of all services that we evaluated.
I previously selected mailgun because of a PHP framework called Laravel. Since I was using that framework, and they had ready examples with mailgun and how to set things up, I went with the flow. It was really easy. Later when I started deploying my services, I was introduced …
Mailgun's pay-as-you-go pricing structure is fantastic, especially if you don't need to send that much email. The pricing, including the free tier, is much more generous than what you can get with some pricier providers, like SendGrid. I mainly just use Mailgun as an SMTP server for web services, and the service has been set-up-and-forget, which is great because I never even have to log onto the Mailgun website and do any work. Mailing list support also looks great for rolling-your-own and not relying on more expensive mailing list services.
No built-in templating features (This was a bit sad after coming from Mandrill which excelled at this)
Dashboard UI (although easy to use) is a bit dated in appearance
Logs are cumbersome compared to Mandrill
Setting up TLD (top level domain) names (things like .online or .church) that are not common require an email to tech support (this is annoying)
Sometimes can be slow in delivery
Shared IP addresses can be SPAM filtered or delayed (requires an email to support to have a new one assigned - Note: this can be mitigated by buying a dedicated one for a monthly fee)
It could be more up-to-date and could offer some extra features that other competitors do like templating and better querying and filtering. As it is right now most things are easy to use but seem rather barebones next to Mandrill. The API is easy to implement thanks to the great documentation which is why I recommend Mailgun so often.
There have been a few minor outages through the years, but nothing more than a few minutes. These small outages are to be expected in any kind of a SaaS product, but Mailgun handles them very well. We designed our software to just retry sending after a while if there is an outage. As far as I know, we have never had to do more than a few retry cycles. This is all automated on our end, so we rarely even notice. Our customers have never noticed any mail sending outages.
The API and the deliverability of emails is excellent. Their API is very responsive and performs perfectly fine. I have no complaints there. Their management interface though (accessed through the web) is pretty slow though. Searching through lists of emails when I'm tracking down a problem for a customer can take 10+ seconds which is annoyingly high for a modern web app.
You can't seem to get ANY support until you shell out hundreds of dollars per month. I even did this when we could not deliver mail with Mailgun, and the response was slow and inadequate. Nor would they refund my money. I'll never be a customer of Mailgun again.
To be honest, the tools are quite similar and again I dont recommend using them as a standalone products, but they power the work we do via CRMs and our marketing campaigns. Mailgun integrates slightly better which it is why it is the preferred choice for our agency, as it integrations options seem to be better
Over the past six years, Mailgun has scaled with our growth very easily. We haven't had to make any code changes to handle our larger volume today, and their pricing has scaled naturally with our growth. As far as I know, there is nothing we will need to do in order to grow 10-fold. Mailgun just handles the load really well.
By not investing in our mail server, we have saved huge amount of money and time. For configuration and installation of an email server on Linux-based server, we would have to hire a network administrator.
If email delivery is an issue in a hosting provider, another solution is to switch the hosting. Fortunately with Mailgun, we didn't need to try different hosts and experiment which one works best for emails. We can stick to our existing web hosting provider and would not need to change it just for the sake of improving email deliverability.
The pricing of Mailgun is very cheap and straightforward. First 10K emails are free every month and that's a big advantage for our organization because our volume of emails is rarely more than 10K per month.
