17 AWS SES API PHP Best Practices

When it comes to sending emails programmatically, Amazon Web Services (AWS) Simple Email Service (SES) stands out as a reliable and cost-effective solution. However, to ensure smooth and efficient email delivery using the AWS SES API with PHP, it's crucial to follow best practices. Here are 17 essential best practices to keep in mind:

1. Use the Latest AWS SDK

Always use the latest version of the AWS SDK for PHP. This ensures compatibility with the latest AWS SES features and security updates.

2. Verify Email Identities

Before sending emails, verify your email identities (domains or email addresses) with AWS SES. This enhances deliverability and reduces the chances of your emails being marked as spam.

3. Manage Your Sending Limits

Be aware of your AWS SES sending limits and adjust your email volume accordingly. Sudden spikes in email sending can trigger rate limiting or even suspensions.

4. Handle Bounces and Complaints

Implement a system to handle bounces and complaints. Use the AWS SES notification configurations to receive and process these notifications.

5. Optimize Email Content

Craft your email content carefully. Avoid spammy words, use a balanced text-to-image ratio, and ensure your emails are mobile-friendly.

6. Utilize Templates

Make use of AWS SES templates for consistent email formatting and personalization. Templates simplify the process of creating and sending emails with dynamic content.

7. Monitor Email Deliverability

Regularly monitor your email deliverability metrics, such as open rates, click-through rates, and bounce rates, to identify and address any issues promptly.

8. Implement DKIM and SPF

Enhance your email authentication by implementing DomainKeys Identified Mail (DKIM) and Sender Policy Framework (SPF). These technologies help validate the origin of your emails and reduce spoofing.

9. Handle Unsubscribes Gracefully

Include an unsubscribe link in all your emails and respect user preferences when they choose to opt-out.

10. Test in Different Environments

Test your emails in various email clients and devices to ensure compatibility and display issues are minimized.
