Understanding AWS SES Email Sending Limits

Amazon Simple Email Service (SES) is a highly reliable and cost-effective service for sending emails. However, understanding and managing its sending limits is crucial for maintaining the performance and deliverability of your email campaigns. In this article, we'll dive into AWS SES email sending limits, explain how they work, and provide tips on how to manage them effectively.

What Are AWS SES Sending Limits? AWS SES imposes certain restrictions on the number of emails you can send within a specific time frame. These limits are in place to ensure the stability and reliability of the service for all users. The two primary limits are:

  1. Sending Quota: This is the maximum number of emails you can send in a 24-hour period.
  2. Sending Rate: This is the maximum number of emails you can send per second.

These limits vary depending on whether you're using SES in the Amazon SES sandbox environment or production environment.

Sandbox vs. Production Environment:

  • Sandbox: When you first create an SES account, you're placed in the sandbox environment. Here, your sending limits are much lower, and you're restricted to sending emails only to verified addresses.
  • Production: After your account is moved to production, you can send emails to any address, and your sending limits are increased.

Managing and Requesting Limit Increases: If your email sending needs exceed your current AWS SES limits, you can request a limit increase. Here’s how you can manage and potentially increase your SES sending limits:

  1. Monitor Your Usage: Regularly check your sending quota and rate using the SES console or AWS CLI.
  2. Request a Limit Increase: If you’re approaching your limits, submit a request to AWS Support for a higher quota or sending rate. Be prepared to provide details about your use case and anticipated email volumes.
  3. Optimize Your Email Sending: Reduce unnecessary emails and improve targeting to stay within your limits. This is where Sendune comes in handy.

How Sendune Helps with AWS SES Limits: Sendune allows you to efficiently manage your email campaigns by tracking user actions and sending targeted messages using AWS SES. By segmenting your users and sending more relevant content, you can make the most of your AWS SES sending limits. Additionally, with Sendune’s automation rules, you can optimize the timing of your emails to spread out your sending rate, avoiding sudden spikes that could hit your limit.

Conclusion: Understanding and managing your AWS SES email sending limits is crucial for successful email campaigns. By monitoring your usage, requesting increases when necessary, and leveraging tools like Sendune, you can ensure that your email deliverability remains high and your campaigns are effective.
