Why Lambda function does not send email

Question

Hi

I am testing a lambda function that sends an email via SES.
I created an IAM role with SES full access and attached it to function.
I created an identity in SES for the source email and target email and verified both accounts.
I created a domain because I was not sure if this is required or not to send emails out.

When I run the function it runs fine but I don't receive any emails in target email.
I do get an email error for non delivery in the source email shown below.

When I click on cloudwatch logs, I do see this message even though it is not affecting the execution of function:
Log group does not exist
The specific log group: /aws/lambda/Test_sendemail does not exist in this account or region.

Do you know why I am not receiving any emails after I run the function?

```
import json
import boto3

def lambda_handler(event,context):
      client = boto3.client("ses")
      subject = "test subject from Lambda"
      body = "test body from Lambda"
      message = {"Subject": {"Data":subject}, "Body":{"Html":{"Data": body}}}
      response = client.send_email(Source = "test_01@yahoo.com",
                 Destination={"ToAddresses": ["test_02@yahoo.com"]}, Message = message)
      return response
```
  An error occurred while trying to deliver the mail to the following recipients:
test_02@yahoo.com

Test Event Name
(unsaved) test event

Hello.

The most likely reason why CloudWatch Logs cannot be found is that the IAM policy for outputting from Lambda to CloudWatch Logs is not set.  
If you have not set up the IAM policy described in the document below, please try setting it up.

I sent an email using the same code in my environment and was able to confirm sending and receiving without any problems.  
Did it go to your spam mail?
