Using AWS SES, you can send emails from your AWS account and use various features like precise targeting, tracking, customization etc.
If you want to check if your account is in Sandbox mode or not, you can do so by following these steps:
Log into your AWS Console.
Click on the Services icon on the upper left side of the window and then click on ‘Simple Email Service’ or search for ‘SES’.
Once you are in the ‘Simple Email Service’, click on the ‘Domains’ tab.
Scroll down to the ‘Email sending’ tab and look for the status. If it says “Sandbox mode” then your account is in sandbox mode.
