We use Amazon Simple Email Service to auto-respond to users that submit messages through a contact form. We are using Amazon Simple Email Service with our self hosted python application to send our marketing emails, get feedback for our services, and Hackathons.

It works great as an onsite relay to provide email sending functionality without having to pass through the firewall in order to reach the Office 365 gateway. This is particularly evident when using older programs. A lot of the older, no longer developed, programs will only allow a hard coded port to send email. Office 365 uses a non-standard SMTP port for security. This does not allow the hard coded SMTP ports to use this service. Exchange gives you the control to change those ports and securely use the standards without compromise.

Pros
Amazon SES
- Amazon Simple Email Service is a much lower cost than most other solutions and truly makes cost a non-factor in most situations where we consider implementing it.
- The API is so well documented that implementing Amazon Simple Email Service in nearly any application or codebase is achievable with basic coding knowledge.

Cons
Amazon SES
- Even if you do not want to spam, you cant send an email to the unverified users.
- Integration with other services is a bit tricky. To watch the trail, handle bounced emails, save emails on S3 are not straightforward to implement.
- When you want to send a lot of emails (in bulk), it takes a significant amount of time.

- As with any technology on a server, we sometimes see issues with downtime related to network changes or firewall updates.
- It can be a challenge to work with some of our older applications when the TLS feature is used.
- I wish there was a more direct way to reliably use SMTP for mass email sends without the fear of being blacklisted.

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.

We have used a dozen services. They are almost all more expensive. Some force you to wait one week to approve/deny your account if they suspect that the email database is not legal. I have very important clients with legal databases that were rejected by other companies and could send emails from Amazon SES without problems.

Office 365 does use secure non-standard ports for SMTP connectivity causing a problem with older programs. SMTP Email Delivery from Exchange solves this problem by giving the network admin full control over ports and specific program connections. While we do use both Office 365 and the SMTP Email Delivery we find that a mix is needed in order to meet all expectations for our end users. The majority of our SMTP communications, for users, go through Office 365 while the majority of our applications and servers do go through the SMTP Email Delivery service.

Return on Investment
Amazon SES
- SES is still more cost effective than other email services like Mailgun.
- Unless we have a high-traffic month, staying within the free tier is very nice for our bottom line.
- Not having to spend time worrying about SES reliability saves us frustration and money.

- It's the easiest way to send mail out. No worries about complex configurations.
- It can be finicky when used in a hybrid Office 365 environment to get the proper pathways secured and working.
- I wish there were a better way to send out mass emails, on-site, without our domain or server IP being blacklisted.
