Emails may bounce back when they cannot be delivered to the recipient’s inbox. One of the most common reasons is an incorrect or misspelled email address. Even a small error can cause the message to be rejected and returned to you.
Another reason could be issues on the recipient’s side. Their mailbox may be full, inactive, or temporarily unavailable. In some cases, the recipient’s email server may be down or not accepting new messages, which can also result in a bounce back.
Email security and filtering settings can also affect delivery. If your message is flagged as spam or does not meet the recipient’s security policies, it may be blocked. Missing or incorrect email authentication settings, such as domain records, can also cause emails to be rejected.
To resolve the issue, review the bounce message for details, confirm the recipient’s email address, and check your email settings. If the problem continues, a deeper review of your email configuration may be needed to identify and fix the issue.
