If you’ve received a ‘failed delivery’ message after sending an email, it means your message couldn’t reach its destination. These notifications explain why the delivery failed and what you can do next. This article will help you understand what these messages mean and how to fix the problem.
If you receive an email from ‘MAILER-DAEMON’ or ‘Mail Delivery Subsystem’ with a subject such as ‘Failed Delivery’, it means your email couldn’t be delivered and has bounced back to you.
These messages are automatic and usually explain why delivery failed. Bounced messages usually have two parts: the reason for the failure and your original email.
The most common reason is that the email address doesn’t exist. If the message says the account doesn’t exist, check the spelling carefully. Even one wrong letter can cause a delivery to fail.
If the message keeps bouncing, confirm the email address hasn’t been closed or changed.
