Amazon Simple Email Service (Amazon SES) is an outbound-only email-sending service useful for marketing and transactional email, relying on the infrastructure of Amazon. Amazon SES provides the requisite statistics and built-in notifications for bounces, complaints, and deliveries for optimization of campaigns. Emails are sent via SMTP or the Amazon SES API.
Amazon's pricing is per usage, presently at $.10 per thousand sends. The service is free for users of Amazon EC2 (up to 62,000 messages),…

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.

Amazon Simple Email Service comes with the bundle of Amazon Web Services (AWS) and it also offers a limited number of emails per month for free. One who has a technical background and wants to send custom emails with custom domains in a professional way can go with Amazon Simple Email Service. If you have no technical background or tech team, it might not be useful for you.
Even with the list of negatives, Mailgun is still a great solution for how easy it is to work with and how ubiquitous it is to find examples and libraries out there on the internet. The company has great support and are usually quick to address and fix things. I do think they have some room for improvement with the lack of templates and the outdated UI log handling/filtering.
As compare to other vendors that I have integrated response is very quick.
You can verify both domain or email to send out the emails from.
While setup you can easily configure it with your domain with few clicks like adding CNAME, DKIM records
Easy to use with or without access key and secret key within aws servers. You can directly map permissions to servers to go without credentials using boto3.
Mailgun is used by spammers, and sometimes your assigned mail server will get blacklisted because of other users on it.
If you end up with a mail server that is blacklisted, your mail will go nowhere. And, below the $300 and up pricing tiers, there is no one at Mailgun to help you get this problem resolved. You are just stuck.
In other words, Mailgun is unreliable as a mission-critical service. I would strongly recommend using a service with better processes in place.
The time for the initial setup is very quick, since you can start sending (thus developing) from their sandbox in no time. The actual configuration involves, as usual, some DNS changes that may require time but are well explained and documented. Once everything is set up, there are a lot of monitoring tools that you can use to optimize your lists.
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.
We did not have the need of contacting Amazon for support. The documentation they provide is of great quality. Examples are easy to follow. One thing to have into consideration is we didn't have the premium support for AWS, so I can't provide details on how good or bad this service is, but in general, the basic support I had was great.
MailGun's support staff is both friendly and helpful. They were very instrumental early on with helping out during the setup process by answering questions, providing documentation on best sending practices, detailing information about the advantages of sending from a dedicated IP rather than an IP pool, and helping us to remove ourselves from blacklists.
Mailchimp has a fixed monthly price, and with the number of emails that we sent, it's pretty expensive. Since our mailings are quite infrequent, using Mailchimp didn't make financial sense for us, even though Mailchimp is a more polished, packaged solution for email marketing. We evaluated other email delivery solutions as well and didn't find anything that matches Amazon SES on reliability and pricing.
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 Accelerate Program too.
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.
Amazon Simple Email Service has improved delivery rates and eliminated delivery issues everywhere we have impelmented it.
We have been able to enforce stricter security within our application environments because we are using Amazon Simple Email Service instead of handling email transmissions natively.
