Hard Bounce
A hard bounce
A hard bounce is an email delivery failure that occurs when an email cannot be delivered
There are several reasons why a hard bounce may occur. One common reason is an invalid or non-existent email address. This can happen when a recipient mistypes their email address, or when an email address is no longer in use or has been deleted. Another reason for a hard bounce is when the recipient’s email server rejects the email due to spam
When an email experiences a hard bounce, it is typically returned to the sender with an error message indicating the reason for the failure. This error message can provide valuable information to the sender, allowing them to update their mailing list
Hard bounces are important to monitor and manage because they can impact email deliverability and sender reputation. If a sender has a high rate of hard bounces, it can signal poor list hygiene or potential spamming activities, which can lead to being marked as a spammer by email service providers. This can result in future emails being blocked
