 This sandbox setup is to help developers start building the application. Once you have established a sender reputation by sending mails, you can request to increase the sending volume limits. Submit a [support request](https://azure.microsoft.com/support/create-ticket/) to raise your desired email sending limit if you require sending a volume of messages exceeding the rate limits. Email quota increase requests are not automatically approved. The reviewing team will consider your overall sender reputation, which includes factors such as your email delivery failure rates, your domain reputation, and reports of spam and abuse when determining approval status.
