Feature Request:
Please build into Manychat some default behavior for handling Critical SMS Errors.

Expected Behaviors: 

1. When Manychat receives a response from the Twilio API that contains an error message (Example: Error 30003); notify the Admin of the Manychat account.
2. Admin should be able to indicate how Manychat should handle those errors. Options should include:
   1. Ignore Error 30003 
   2. Update Contacts 
   3. Start Flow 
3. Admin should no longer be notified about Error 30003, but will get notifications about other errors. 

Background & Issue: 
For the last 24 months, I’ve been sending SMS messages on a monthly basis. I’ve recently notice that each month, my percentage of the SMS messages that are UNDELIVERED is going up. I am being triple charged for these messages; for each failed SMS I’m paying Manychat, Twilio, and the phone carrier.
