To prevent fraud and abuse AWS puts new accounts in 'Sandbox Mode' with certain restrictions. Follow the below steps to get out of the Sandbox and increase your sending limits.
That’s it. AWS will take a few hours to respond. If AWS needs any extra information they will ask you for the same before increasing your limits.
Do not worry if AWS gives you lesser limits than what you asked for. Just send a few emails, wait a few days and submit another limit increase request.
Over time, depending on your usage and reputation, you can continue asking AWS to increase these limits. They will do so gladly but only if your email sending reputation is good. So make sure you don’t send out any unsolicited emails.
Happy email sending.
