Amazon Pinpoint email sandbox

We use a sandbox environment to help protect our customers from fraud and abuse. The sandbox environment also helps you establish your sender reputation with ISPs and email recipients. New Amazon Pinpoint email user accounts are placed in the sandbox environment. While your account is in the sandbox, you have full access to Amazon Pinpoint email sending methods, with the following restrictions:

• You can send email only from verified addresses and domains.

• You can send email only to addresses that you have verified or addresses that are associated with the mailbox simulator.

• You can send a maximum of 200 messages within 24 hours.

• You can send a maximum of one message per second.

To learn how to remove these restrictions, see Requesting a quota increase.
