Airflow Mailgun Plugin

An Airflow hook and operator to validate a list of emails using the Mailgun Email Validation API.

An example Mailgun validation DAG is available as well.

Setup

In the root of your Airflow project run:

$ pip install -U git+https://github.com/airflow-plugins/mailgun_plugin.git@v0.0.1

Quickstart

1. Create an S3 bucket my_bucket on AWS or use an existing one.
2. Upload a list of contacts contacts.json to it which consists of newline-delimited JSON (ndjson):

{"id": 123, "email": "foo@example.com"}
{"id": 456, "email": "bar@example.com"}
{"id": 96, "email": "info@example.com"}
{"id": 433, "email": "Real Person <rperson@example.com>"}

3. Create an S3 connection in Airflow:

- Conn Id: aws_s3
- Conn type: S3
- Login: <AWS Access Key ID>
- Password: <AWS Secret Access Key>

4. Create a Mailgun connection in Airflow:

- Conn Id: mailgun_api
- Conn type: (empty)
- Login: <Mailgun Public Validation Key>

5. Add a task to your DAG like:

dag = DAG(...)

email_validator = EmailValidationOperator(
    task_id='email_validator',
    mailgun_conn_id='mailgun_api',
    aws_conn_id='aws_s3',
    s3_bucket_name='my_bucket',
    s3_key_source='contacts.json',
    dag=dag,
)
