Amazon SES

 Amazon SES, or Simple Email Service, is a cloud-based platform that facilitates the effortless sending of transactional and mass emails. It enables organizations to reach recipients without manual intervention, reducing the risk of emails being marked as spam. Additionally, SES allows integration with SMTP (Simple Mail Transfer Protocol), enhancing email delivery capabilities and ensuring reliable communication.

What is AWS SES?

Simple Email Service is a cloud-based email sending service designed to help digital marketers and application developers send marketing, notification, and transactional emails. It is scalable, cost-effective, and easy to integrate into various applications.

Features of Amazon SNS

• Pub/Sub Messaging: Supports publish/subscribe messaging paradigm where publishers send messages to topics, and subscribers receive messages from topics they are interested in.
• Multiple Protocols: Allows messages to be delivered via multiple protocols such as HTTP, HTTPs Email, SMS, SQS (Simple Queue Service, Lambda and more, enabling flexibility in message delivery.
• Message Filtering: Provides message filtering policies that allow subscribers to receive only the messages they are interested in based on message attributes.
• Fan-Out: Supports fan-out messaging, where each message published to a topic is delivered to multiple subscribers asynchronously.
• Message Attributes: Allows attaching metadata (attributes) to messages, enabling subscribers to filter and process messages based on specific criteria.
• Mobile Push Notifications: Integrates seamlessly with mobile app platforms (e.g., Apple Push Notification Service, Google cloud messaging) to deliver push notifications to mobile devices.
• Redundancy and Durability: Ensures high availability and durability of messages through replication across multiple availability zones within a region.
• Message Encryption: Supports encryption of messages both in transit (using HTTPS) and at rest (using AWS KMS encryption).
• Monitoring and Metrics: Provides detailed monitoring of message delivery, including metrics such as delivery rates, message failures, and success rates.
• Simple API: Offers a straightforward API and SDKs for easy integration with applications and services, simplifying the process of sending and receiving messages.

Working of Amazon SES

Amazon SES (Simple Email Service) works in a straightforward manner to facilitate the sending and receiving of emails. Here’s a simple overview of how Amazon SES operates:

• Sending Emails:
  • Integration: You integrate Amazon SES into your application or service using the AWS Management Console, AWS SDKs, or SMTP interface.
  • Email Content: You specify the content of the email, including recipients, subject, body (HTML/text), and attachments.
  • Authentication: Amazon SES authenticates your identity to ensure emails are sent from verified domains or email addresses.
• Message Routing:
  • API Call or SMTP: Emails are sent via API calls directly to the Amazon SES API or through SMTP.
  • Email Processing: Amazon SES processes the email, handling tasks such as message formatting and ensuring compliance with email sending policies and regulations.
• Email Delivery:
  • Routing: Amazon SES routes the email through its infrastructure to ensure reliable delivery.
  • Feedback Loop: Provides bounce and complaint notifications to help manage the reputation of your sending domain.
• Receiving Emails:
  • Configuration: Optionally, you can configure Amazon SES to receive emails by setting up receipt rules and actions.
  • Processing: SES can deliver received emails to Amazon S3 buckets, invoke AWS Lambda functions, or publish notifications via Amazon SNS.
• Monitoring and Reporting:
  • Metrics: Amazon SES provides metrics and reports on email sending activity, delivery rates, bounces, and complaints.
  • Logs: Detailed logs are available for troubleshooting and monitoring email delivery.

Quotas

Sandbox Account (Default or Free Account)

• The user can only send 1 email/s and 200 emails/day.
• The user can only send emails from/to verified identities/users.
• If users want to send emails to unverified users, they should shift to a Production Account.
• Maximum message size (MB) of 10 for the maximum message size that you can send.

SMTP

The Simple Mail Transfer Protocol (SMTP) is an Internet standard communication protocol for electronic mail transmission. Mail servers and other message transfer agents use SMTP to send and receive mail messages.

 

Steps to Send your First Email with AWS SES

Step 1: Navigate to the AWS Management Console and search for “SES”.

Step 2: From the left-hand menu, select “Verified Identities”. Here, you can verify sender and receiver email addresses for sending and receiving emails. Email addresses must be verified before they can be used with SES. Click “Create Identity”.

Step 3: Add your email address or domain and click “Create Identity” at the bottom of the page.

Step 4: An email verification will be sent to the address you added. Click the verification link in the email to complete the process.

Skip to STEP 8 if you don’t want to connect the SES server to your backend.

Step 5: (Optional for backend integration) From the left-hand menu, select “SMTP Settings”. Create SMTP credentials by adding a username and clicking “Create User”.

Step 6: Add a User name and Create a User.

Step 7: Note down or download the SMTP credentials generated.

Step 8: Return to “Verified Identities” to verify if your email address is successfully verified. To send a test email to another address, click “Send test email”.

Step 9:

• Select Scenario as Custom which will allow you to send emails to others custom email addresses.
• Remember if you put any unverified email address this will not work, to test you can send this to yourself or just add another email address and verify it.
• Add Subject and Body for your email.

Step 10: Check your mailbox for your test email.

Step 11: Let’s try once more sending it to another verified email address.

Note: I’ve verified other mail to test this. You can follow Steps 1-3 again to verify other email addresses.

Sent Test 2 Mail

Step 12: Check your other mailbox for your test email.

Understanding Email Sending Advantages, Disadvantages and Costs

Advantages

• Cost-effective: SES is one of the most cost-effective ways to send emails as AWS charges based on the number of emails sent there are no additional costs.
• Security: It uses multiple layers of security to protect email data such as encryption, access controls, and spam and phishing filters.
• Scalability: It can handle large volumes of email messages which makes it a perfect way for businesses that need to send out mass emails.

Disadvantages

• Limited customization: It offers a wide range of features, but it doesn’t offer the same level of customization as some other email services.
• Potential for delivery issues: There is always a small chance that your emails will not be delivered, due to the recipient’s spam filters.
• Reputation management: If you send out too many emails or they are marked as spam, your reputation with SES can be damaged.

Use cases

• Transactional emails: Emails that are triggered by an event, such as a password reset email or a purchase confirmation email.
• Marketing campaigns: It can be used to send out newsletters, promotional emails, and other marketing content.
• Notifications: SES can be used to send out notifications to users, such as system alerts or appointment reminders.

Applications

• Netflix: They use SES to send out a variety of emails, like password reset emails, billing reminders, and movie recommendations.
• Dropbox: They use SES to send out file-sharing notifications, account verification emails, and password reset emails.
