Here's the complete code in text format for integrating AWS Lambda with S3, retrieving email IDs from a file, and sending emails using the SES service:
import boto3
def lambda_handler(event, context):
??# Retrieve email IDs from the S3 file
??email_ids = retrieve_email_ids_from_s3()
???
??# Send emails using SES for each email ID
??send_emails(email_ids)
def retrieve_email_ids_from_s3():
??s3_client = boto3.client('s3')
??bucket_name = 'your-bucket-name'?# Replace with your S3 bucket name
??file_key = 'emails.txt'?# Replace with your file key
???
??# Get the file from S3
??response = s3_client.get_object(Bucket=bucket_name, Key=file_key)
??file_content = response['Body'].read().decode('utf-8')
???
??# Extract email IDs from the file content
??email_ids = file_content.split('\n')
???
??return email_ids
def send_emails(email_ids):
??ses_client = boto3.client('ses', region_name='your-region')?# Replace with your desired AWS region
???
?sender_email = '[email protected]'?# Replace with your sender email address
???
??for email_id in email_ids:
????# Create a personalized email for each recipient
????recipient_email = email_id.strip()
????subject = 'Hello from AWS Lambda!'

????message = f"Dear {recipient_email},\n\nThis is a sample email sent using AWS Lambda and SES. Have a great day!"

????# Send the email
????response = ses_client.send_email(
??????Source=sender_email,
??????Destination={
????????'ToAddresses': [recipient_email]
??????},
??????Message={
????????'Subject': {
??????????'Data': subject
????????},
????????'Body': {
??????????'Text': {
????????????'Data': message
??????????}
????????}
??????}
????)
?????
????print(f"Email sent to {recipient_email}: {response['MessageId']}")
```
Make sure to replace the placeholders with your specific values:
- `'your-bucket-name'`: Replace with the name of your S3 bucket where the file containing email IDs is located.
- `'emails.txt'`: Replace with the key of the file in your S3 bucket.
- `'your-region'`: Replace with the AWS region where you want to use SES (e.g., `'us-east-1'`).
- `'[email protected]'`: Replace with the email address you want to use as the sender.
Note: Make sure to have the necessary IAM permissions for Lambda to access S3 and SES services. Additionally, configure the Lambda function trigger and role appropriately.
This code is designed to be used as an AWS Lambda function. When triggered, it retrieves the email IDs from a file in S3, then sends personalized emails to each retrieved email ID using the SES service.
