These restrictions are only for the SES sandbox mode. You fill in a form to get out of sandbox mode and then you can send many more per day (still only 14/second or so).

You only verify addresses you want to send from (for testing you might verify one to try sending to as per the sandbox rules). You wouldn't get customers to verify their addresses here, as that would let you send email on their behalf.
