An Email Hard Bounce occurs when an email does not reach the recipient due to permanent issues such as invalid addresses, server shutdowns, or misspelled email addresses. Email Hard Bounce Rate gives the percentage of emails sent that are hard bounces.
To bring down your Email Hard Bounce Rate, try to maintain a clean and updated email list. Following best practices such as double opt-in and email verification while adding contacts to your email list will usually keep your bounce rate to a minimum.
