Integration Methods

1. AWS SDK Integration

Code example for Node.js:

const AWS = require('aws-sdk');
const ses = new AWS.SES({region: 'us-east-1'});

const params = {
Destination: {
ToAddresses: ['[email protected]']
},
Message: {
Body: {
Html: {
Data: 'Hello from AWS SES!'
}
},
Subject: {
Data: 'Test Email'
}
},
Source: '[email protected]'
};

ses.sendEmail(params).promise()
.then(data => console.log('Email sent:', data))
.catch(err => console.error(err));

2. SMTP Integration

Python example using smtplib:

import smtplib
from email.mime.text import MIMEText

# SMTP credentials from AWS
smtp_username = "YOUR_SMTP_USERNAME"
smtp_password = "YOUR_SMTP_PASSWORD"
smtp_host = "email-smtp.us-east-1.amazonaws.com"
smtp_port = 587

msg = MIMEText('Hello from AWS SES!')
msg['Subject'] = 'Test Email'
msg['From'] = "[email protected]"
msg['To'] = "[email protected]"

with smtplib.SMTP(smtp_host, smtp_port) as server:
server.starttls()
server.login(smtp_username, smtp_password)
server.send_message(msg)
