What is a Hard Bounce?

A Hard Bounce means that there is a permanent reason an email cannot be delivered to a specific subscriber.

Hard bounced email addresses are automatically removed from your Email Marketing Mailing list and transferred to the "Bounced" category.

The most common reasons why a hard bounce might occur are:

  • the recipient misspelled their email address while subscribing
  • the recipient has deleted, changed their email address or provided you with a false address
  • the recipient's mail server has blocked your server
