API throttling and timeouts

Your Azure account limits the number of email messages that you can send. For all developers, the limits are 30 mails sent per minute and 100 mails sent per hour.

This sandbox setup helps developers start building the application. Gradually, you can request to increase the sending volume as soon as the application is ready to go live. Submit a support request to increase your sending limit.
