📧 Serverless Email Marketing Application

This project is a hands-on tutorial demonstrating how to design and build a simple serverless email marketing application using AWS services. The application sends emails on a schedule, pulling HTML email templates and a list of contacts from an S3 bucket.

🛠️ AWS Services Used

• 📤 Simple Email Service (SES): To send emails.
• ⏰ EventBridge: To schedule email sending.
• 📦 S3: To store email templates and contact lists.
• 📝 Lambda: To handle the logic for sending emails.
• 🔒 Identity & Access Management (IAM): To manage permissions and roles.

📝 Prerequisites

• 📧 Email Addresses: You need email addresses that you can validate (both sender and receiver).
• 🌐 Domain: The sender's email address must be from your own domain.
• 🧠 Basic AWS Knowledge: Familiarity with AWS services and the AWS Management Console.
• 🖊️ Text Editor: To write or edit HTML code for the email templates.

🚀 Getting Started

Step 1: Set Up S3 Bucket

1. Create an S3 bucket to store your HTML email templates and contact list.
2. Upload the provided email_template.html and contacts.csv to your S3 bucket.

Step 2: Configure Amazon SES

1. Set up Amazon SES with your domain and validate email addresses.
2. Move SES out of the sandbox environment to remove limitations.

Step 3: Develop Lambda Function

1. Create a Python Lambda function that retrieves the email template and contact list from S3, personalizes the emails, and sends them via SES.
2. 🧪 Test your Lambda function to ensure it works correctly.
3. Update the Lambda execution role with the necessary permissions for S3 and SES.

Step 4: Schedule Email Sending with EventBridge

1. Create an EventBridge rule to trigger your Lambda function on a schedule.
2. 🧪 Test the EventBridge schedule to ensure emails are sent as expected.

Step 5: 🧹 Cleanup

1. After testing, make sure to delete all AWS resources (S3 bucket, SES configurations, Lambda functions, EventBridge rules) to avoid incurring unnecessary charges.

💡 Enhancements

Here are a few ideas to extend the functionality of this application:

• Add support for multiple email templates.
• Implement a retry mechanism for failed emails.
• Integrate with a database like DynamoDB to store campaign results.
