Understanding Email Bounce

Before delving into the process of checking email bounce online, it's crucial to understand what exactly an email bounce is. In simple terms, an email bounce occurs when an email cannot be delivered to the intended recipient. There are two main types of email bounces - hard bounce and soft bounce.

Hard Bounce

A hard bounce happens when an email is permanently rejected due to reasons such as an invalid email address, a non-existent domain, or the recipient's email server blocking the email. It's important to identify and remove hard bounces from your email list promptly to maintain a good sender reputation.

Soft Bounce

On the other hand, a soft bounce is a temporary issue that prevents the delivery of an email. Reasons for soft bounces include a full mailbox, a server timeout, or the recipient's email server being down. Soft bounces can be resolved by re-sending the email at a later time.
