 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.

-> Email quota increase requests may take up to 72 hours to be evaluated and approved, especially for requests that come in on Friday afernoon.

-You can optionally configure your MailFrom address to be something other than the default DoNotReply, and also add more than one sender username to your domain. To understand how to configure your sender address, see how to [add multiple sender addresses](add-multiple-senders.md).

-> [!NOTE]
-> Azure Managed Domains facilitate developers in rapidly initiating application development. Once your application is prepared for deployment, you can seamlessly integrate your custom domain. It's crucial to note that if you continue to rely on Azure Managed Domains, the MailFrom Address displayed in the recipient's mailbox will differ from what you observe in the Portal. This address is dynamically generated, dependent on the data location. As an illustration, if the data location is set to the US, the received email address will transform into 'donotreply@xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx.US1.azurecomm.net'. If you would like to send high volume of messages, you have to switch to custom domain as Azure Managed Domain has the limitations on the number of email messages you can send as defined in the [Email Service Limits](../../concepts/service-limits.md).
