What is the best way to get an update on an appeal after submission?

The best way to get an update on an appeal after submission is by responding to the email from the appeals team. This option is correct because the appeals team usually communicates updates and information related to the appeal process through email. By responding to their email, you ensure that your inquiry is directed to the appropriate personnel who are handling your case, allowing them to provide you with the most accurate and timely information regarding your appeal's status.

In contrast, calling the Customer Support Center, while potentially useful, may not provide specific information on your appeal unless the representatives have access to your case. Sending up fireworks is obviously not an effective or appropriate method for inquiring about an appeal and does not facilitate communication. Emailing the organization directly might lead to confusion or delay, as you may not reach the specific appeals team that is already familiar with your case, making it less efficient for receiving updates.
