I am developing PHP application that, after sign-up, sends an activation mail to the registered email address using Amazon SES (Simple Email Service).
But SES is only sending emails to verified users.
How can I send the activation link to any non-verified email address, too?
While running in sandbox mode you can only send to verified users - once your account has been activated, you can send to anyone.
Getting out of the sandbox:
