What are the email statuses when sending to customers and how to handle errors

Possible statuses and causes when sending to customers:

• Delivered: The email has been successfully sent to the recipient’s mail server (Note: This status does not guarantee that the email has been read by the recipient).
• Pending:
  • Reason: The email is in the sending queue and hasn’t been processed yet. This could be because the system is busy or the network connection is slow.
  • Troubleshooting: Wait a short period and check the status again. If the situation persists, contact support.
• Error = Bounce: The email could not be delivered to the recipient’s address.
• There are several types of bounces:
• Permanent (Hard bounce):
  • Reason: The email address does not exist.
  • Troubleshooting: Double-check the recipient’s email address and ensure it is correct. If not, you need to collect the correct email address from the recipient.
• Transient (Soft bounce):
  • Reason: A temporary error occurred, such as the recipient’s mailbox being full, the recipient’s server being overloaded, or the server being unavailable.
  • Troubleshooting: You can try resending the email after a while.
• Undetermined:
  • Reason: The specific sending error could not be determined.
  • Troubleshooting: Try resending the email. If it still fails, contact support for further investigation.
• Complaint: The recipient has reported your email as spam or containing inappropriate content.
• Abuse (Spam):
  • Reason: The email was reported as spam.
  • Troubleshooting: Do not resend the email to this person. Review your content and how you collect other email addresses to avoid being reported as spam in the future.
• Fraud:
  • Reason: The email content was reported as fraudulent.
  • Troubleshooting: Do not resend the email to this person. Review your email content to ensure transparency and compliance with regulations.
