This milestone will focus on setting up the foundational infrastructure for sending emails, including the email service, database, and RabbitMQ integration.

Email Sending Functionality (Nodemailer)

• Configure Nodemailer with SMTP settings.
• Create EmailService to handle email sending logic.
• Create an API endpoint to send emails via the EmailService.

Validation and Testing

• Define Zod schemas for validating incoming email data.
• Integrate Zod validation into the email-sending API endpoint.
• Write unit tests for the EmailService, database models, and RabbitMQ integration.
• Perform integration testing (sending emails, queue processing).
