Sample Lambda Function with SES integration

Introduction

This simple code is a deployable example of a lambda/ses integration. It's using SAM for deployment purposes, so it's a matter of running a couple of commands in order for you to get started quickly and efficiently.

Who would want to use this?

If you decided to host a static website on S3 but still want people to send you emails through your contact page, this might be a really nice solution for you. The combination of S3, API Gateway, Lambda, & SES covers the basis for a lot of website owners.

Setup

In order for this to work, you need to authorize the receiver (DESTINATION_EMAIL) of your setup. Otherwise SES will throw an exception saying that the destination email isn't verified. More info here: Verifying Email Addresses in Amazon SES

Running the cloudformation scripts will provision the needed resources, including API Gateway and Lambda, which might incur some costs
