Amazon SES only sends to verified email - How-To Guides - Build a Serverless Web Application - Manage Users - Implementation - Validate your implementation

I am following the instructions beginning with step 1 of the title How-To Guide and clicking on "Let's Ride". This is supposed to add the email to the Cognito user pool and send a confirmation code to the user's email.

The following error is printed:

CodeDeliveryFailureException: Cognito received the following error from Amazon SES when attempting to send email: Email address is not verified. The following identities failed the check in region US-EAST-2: charlesXXXX@gmail.com

This process does create the user in the Cognito user pool but the email with the verification code is not sent.

Would I be able to send to unverified email addresses with Amazon SES if I move out of the sandbox?
