Email marketing is an effective way to engage with your customers and prospects. However, with the increasing number of email campaigns, it’s becoming increasingly difficult to ensure that your emails land in your recipients’ inbox. Oftentimes, emails get bounced back, and this can happen for a variety of reasons. One of the kinds of email bounces is a hard bounce. In this article, we’ll explain what hard bounce email is and how it impacts your email campaigns.

What is Hard Bounce Email?

A hard bounce email refers to an email that fails to deliver to the recipient’s mailbox due to permanent delivery errors. These errors include invalid email addresses, non-existing domains or email addresses that have been deactivated or closed. Hard bounces are permanent and cannot be resolved or re-sent.

Why Hard Bounces Matter?

Hard bounces have a significant impact on your email campaigns. The higher your hard bounce rate, the more likely your sender reputation will be damaged. Internet Service Providers (ISPs) track the sender’s reputation to determine whether to deliver the emails to the recipient’s inbox or spam folder. A high bounce rate means that your email is more likely to be marked as spam or blocked, which can decrease your email deliverability rate and damage your sender reputation.

How to Prevent Hard Bounces?

To avoid hard bounces, it’s essential to verify the email list you’re using for your email campaigns. Use an email verification service like UseBouncer.com to identify invalid, risky and non-existent email addresses, typos, syntax errors, and spam traps. These services use advanced algorithms to check email addresses in real-time, ensuring higher deliverability rates and better sender reputation. It’s also a good practice to clean your email list regularly to remove inactive or invalid email addresses.


In conclusion, hard bounces are permanent delivery errors that prevent emails from reaching the recipient’s mailbox. They can damage your sender reputation and decrease your email deliverability rate. To avoid hard bounces, it’s essential to verify your email list regularly and clean it of invalid and risky email addresses.
