Amazon SES for support desk app?

I'm thinking of developing simple support desk solution for a niche. A bit specific niche which interconnects with another system and makes it sub-optimal to use some of ready made solutions like ZenDesk (even with their API).

However, I don't have much experiance with handling important mail in my apps. I really love AWS and use many services there so my first though obviously is to use SES for that part. But I'd like to hear about alternatives or downsides.
