Gmail is one of the most popular email services in the world. It offers a wide range of features, including the ability to send and receive emails. However, sometimes emails can bounce back, which can be frustrating for both the sender and the recipient. In this article, we will discuss how to troubleshoot and avoid bounced emails in Gmail.

What is a Bounced Email?

A bounced email is an email message that is returned to the sender because it was unable to be delivered to the recipient's email address. This can happen for various reasons, such as an invalid email address, a full mailbox, or a spam filter that blocks the email.

How to Troubleshoot Bounced Emails in Gmail

If you receive a bounced email in Gmail, the first thing you should do is check the reason why it bounced back. Gmail provides a bounce message that explains why the email was returned. Here are some common bounce messages and what they mean:

  • Recipient address rejected: This means that the email address is invalid or does not exist.
  • Mailbox full: This means that the recipient's mailbox is full and cannot receive any more messages.
  • Message rejected due to content: This means that the email was blocked by a spam filter because it contains suspicious content.

If you are the sender and your email bounced back, you should check the recipient's email address and try resending the email. If the problem persists, you may need to contact the recipient and ask them to whitelist your email address or check their spam folder.
