Amazon Simple Email Service (SES)

Amazon Simple Email Service (Amazon SES) is a cloud email service provider that can integrate into any application for bulk email sending. Whether you send transactional or marketing emails, you pay only for what you use. Amazon SES also supports a variety of deployments including dedicated, shared, or owned IP addresses. Reports on sender statistics and a deliverability dashboard help businesses make every email count.

Prerequisite Tasks

To use these operators, you must do a few things:

Generic Parameters

aws_conn_id

Reference to Amazon Web Services Connection ID. If this parameter is set to None then the default boto3 behaviour is used without a connection lookup. Otherwise use the credentials stored in the Connection. Default: aws_default

region_name

AWS Region Name. If this parameter is set to None or omitted then region_name from AWS Connection Extra Parameter will be used. Otherwise use the specified value instead of the connection value. Default: None

verify

Whether or not to verify SSL certificates.

  • False - Do not validate SSL certificates.

  • path/to/cert/bundle.pem - A filename of the CA cert bundle to use. You can specify this argument if you want to use a different CA cert bundle than the one used by botocore.

If this parameter is set to None or is omitted then verify from AWS Connection Extra Parameter will be used. Otherwise use the specified value instead of the connection value. Default: None

botocore_config

The provided dictionary is used to construct a botocore.config.Config. This configuration can be used to configure Avoid Throttling exceptions, timeouts, etc.

Example, for more detail about parameters please have a look botocore.config.Config
{
    "signature_version": "unsigned",
    "s3": {
        "us_east_1_regional_endpoint": True,
    },
    "retries": {
      "mode": "standard",
      "max_attempts": 10,
    },
    "connect_timeout": 300,
    "read_timeout": 300,
    "tcp_keepalive": True,
}

If this parameter is set to None or omitted then config_kwargs from AWS Connection Extra Parameter will be used. Otherwise use the specified value instead of the connection value. Default: None

Note

Specifying an empty dictionary, {}, will overwrite the connection configuration for botocore.config.Config

Operators

Send an email using Amazon SES

To send an email using Amazon Simple Email Service you can use SesEmailOperator.

The following example shows how to send a basic email:

tests/system/amazon/aws/example_ses.py[source]

# Basic email sending
# Note: In SES sandbox mode, both sender and recipient must be verified.
send_basic_email = SesEmailOperator(
    task_id="send_basic_email",
    mail_from=verified_email,
    to=[verified_email],
    subject="Test Email from Airflow",
    html_content="<h1>Hello</h1><p>This is a test email sent via Amazon SES.</p>",
    aws_conn_id="aws_default",
)

You can also send emails with CC and BCC recipients:

tests/system/amazon/aws/example_ses.py[source]

# Email with CC and BCC
send_email_with_cc_bcc = SesEmailOperator(
    task_id="send_email_with_cc_bcc",
    mail_from=verified_email,
    to=[verified_email],
    cc=[verified_email],
    bcc=[verified_email],
    subject="Test Email with CC and BCC",
    html_content="<h1>Hello</h1><p>This email has CC and BCC recipients.</p>",
    aws_conn_id="aws_default",
)

For more advanced use cases, you can add custom headers and set reply-to addresses:

tests/system/amazon/aws/example_ses.py[source]

# Email with custom headers and reply-to
send_email_with_headers = SesEmailOperator(
    task_id="send_email_with_headers",
    mail_from=verified_email,
    to=[verified_email],
    subject="Test Email with Custom Headers",
    html_content="<h1>Hello</h1><p>This email has custom headers.</p>",
    reply_to=verified_email,
    return_path=verified_email,
    custom_headers={"X-Custom-Header": "CustomValue"},
    aws_conn_id="aws_default",
)

The operator also supports Jinja templating for dynamic content:

tests/system/amazon/aws/example_ses.py[source]

# Email with template variables
send_templated_email = SesEmailOperator(
    task_id="send_templated_email",
    mail_from=verified_email,
    to=[verified_email],
    subject="DAG Run: {{ dag.dag_id }} - {{ ds }}",
    html_content="""
    <h1>DAG Run Report</h1>
    <p>DAG ID: {{ dag.dag_id }}</p>
    <p>Execution Date: {{ ds }}</p>
    <p>Run ID: {{ run_id }}</p>
    """,
    aws_conn_id="aws_default",
)
