Why has my email bounced back saying it has not been delivered?

Reasons email are not received

  1. Invalid Email Address: This is the most common reason why your email might bounce back. If you've entered the wrong email address or made a typo, your email will never reach its intended recipient. See related article:

  2. Full Mailbox: If the recipient's mailbox is full, your email will be rejected and returned to you. This is because there is no space left in their inbox to receive new messages.
  3. Spam Filter: Many email providers have built-in spam filters to protect their users from unwanted or unsolicited emails. If your email contains certain words or phrases that trigger the spam filter, it might be blocked and returned to you. Ask the recipient (by a different method such as a phone call) to add your email address to their whitelist.
  4. Server Issues: Sometimes, email servers can experience technical issues that prevent them from receiving or sending messages. If the recipient's email server is down or experiencing problems, your email may not go through.
  5. Size Limits: Some email providers set limits on the size of attachments that can be sent or received. If your email and its attachments are too large, it may be rejected and returned to you.

In summary, there are several reasons why your email may have bounced back. Double-check the email address, make sure the recipient's mailbox is not full, avoid using trigger words, and keep attachments within size limits.

If all else fails, contact the recipient using a different method.
