AWS SES on Lambda - fails (silently) to send email

I'm trying to use the service on a in order to send an email to verified recipients.

I'm following this simple tutorial which shows a simple function:

var aws = require('aws-sdk');
var ses = new aws.SES({region: 'us-east-1'});

exports.handler = (event, context, callback) => {

     var params = {
        Destination: {
            ToAddresses: ["recipientEmailAddress"]
        },
        Message: {
            Body: {
                Text: { Data: "Test" }
            },
            Subject: { Data: "Test Email" }
        },
        Source: "sourceEmailAddress"
    };

     ses.sendEmail(params, function (err, data) {
        callback(null, {err: err, data: data});
        if (err) {
            console.log(err);
            context.fail(err);
        } else {                
            console.log(data);
            context.succeed(event);
        }
    });
};

The following policy is part of the lambda's role:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "ses:SendEmail"
            ],
            "Resource": "*"
        }
    ]
}

For some reason, this lambda function fails to send any emails and it doesn't provide any status information inside the function's CloudWatch Log group:

REPORT RequestId: XXX   Duration: 534.59 ms Billed Duration: 600 ms Memory Size: 128 MB Max Memory Used: 117 MB


Any help would be appreciated.


EDIT: I work in sandbox-mode and both source and recipient are verified emails from the region mentioned in the code (It is also reflected in the logs - no errors being thrown).

I Found the following questions in SO - but no relevant answer to my case:

Put callback(null, {err: err, data: data}); to the last, after else block to see what will be throw out. – hoangdv
Seems like the function is getting timed out, have you launched it in VPC ? Try to launch it without VPC ? – James Dean
No Timeout - the function returns successfully after 534.59 [ms] (see in the log above). Launched without VPC. – RtmY
any solution here? I suppose not... – osullic

Your code is perfectly fine. I just tried using your code and it has no problem.

I would recommend you check your identities setting and sandbox-mode.

If you are still in a sandbox-mode, it only allows you to send an email from a verified email address to other verified email addresses.

This documentation will be helpful.

I think context.succeed is deprecated. Also you can use async/await:

exports.handler = async (event, context) => {

 var params = {
    Destination: {
        ToAddresses: ["recipientEmailAddress"]
    },
    Message: {
        Body: {
            Text: { Data: "Test" }
        },
        Subject: { Data: "Test Email" }
    },
    Source: "sourceEmailAddress"
};

const data = ses.sendEmail(params).promise()
return data
};
