This is happening because Cognito sends a confirmation email every time a new user is created in an user pool. By default, Cognito uses its own email service, which has a limit of 50 emails per day. You can deactivate the confirmation email and circumvent the limit and be able to import all of your 312 users. But if you want to import all the 312 users and also send confirmation emails to all 312 again, you need to configure SES and link it to Cognito.
