Notes on AWS SES

If you are in SES sandbox, you have to verify both sender and receiver email addresses. But, If you have migrated out of SES sandbox, sender mail alone must be verified.
Best practice is to use IAM roles compared to hardcoding AWS credentials in application. For the IAM roles related to SES, take a look at the sesIAMRole branch.

Instructions to deploy:

Clone this repo:

git clone https://github.com/lakshmantgld/aws-ses-serverless-example.git

Install the dependencies:

cd aws-ses-serverless-example && yarn install or npm install

Set the AWS credentials as environment variables like described below:

AWS_SECRET_ACCESS_KEY=<secret-key>
AWS_REGION=<region>
AWS_ACCESS_KEY_ID=<access-key>

The above credentials are required for deploying the Lambda and APIGateway using serverless

Rename the config.copy.json to config.json.
Fill the above AWS credentials to config.json. As SES uses this credentials to send mail. Presently, SES supports only in US East, US West & EU(Ireland). So, If your region is not supported by SES, make sure you select the above regions and add it to the config.json.
Finally, deploy the app by running sls deploy -v.
Once the deployment completes, you can send mail by invoking the URL with the following parameters.

{
	"bccEmailAddresses": [],
	"ccEmailAddresses": [],
	"toEmailAddresses": ["****@gmail.com"],
	"bodyData": "Hey test message buddy!! From AWS SES",
