As of now, it is not possible to segment contacts by an error (sending outbound sms, email or other channels).
A client of mine has sent 132 emails to verified email addresses through an automation and 40 (33%!) were returned with the error message "mailbox unavailable", despite the same email addresses were available for manual email sending. How did he find out those 40 out of 132? He had to click through each contact.
Required: Filter by
  • Error Boolean (exists or does not exist)
  • Error Message,
  • Error Date,
  • Channel, where the error was experienced
