You may receive alert emails from Twilio when there’s an error generated by an application you’re running.
These Alert triggers provide a way for you to get notifications on any potential issues with your application. By default Twilio has three triggers in place when an account is initially created: emails will be sent to the account owner when the 1st, 10th and 100th application error occurs each day.
When you receive an email like this, check out the Debugger for detailed error codes and descriptions, or you may want to reach out to whomever developed your Twilio application if you do not maintain it yourself. Read through the article Debugging your application to learn tools in the Console that can help you debug your application.
If you do not need these default triggers, you can click on the “Delete this Trigger” button to remove it after selecting the trigger. To learn about how to create or update a trigger, refer to the article Create or change Twilio Monitor Alert triggers.
