Hard Bounce

Hard bounce is a term used in email marketing to describe when an email is returned to the sender because the recipient’s address is invalid or doesn’t exist. This can happen for a variety of reasons, such as the email address being misspelled, the domain no longer existing, or the recipient’s mailbox being full.

Hard bounces are different from soft bounces, which occur when an email is temporarily undeliverable, such as when the recipient’s server is down or their inbox is full. It’s important for email marketers to monitor hard bounces and remove invalid addresses from their lists to maintain a good sender reputation and improve deliverability rates.

Here are some common reasons for hard bounces:

  • The email address doesn’t exist
  • The domain name doesn’t exist
  • The recipient’s mailbox is full
  • The email server is blocking the email

By regularly cleaning and updating email lists, marketers can reduce the number of hard bounces and improve the overall effectiveness of their email campaigns.
