If you send an email and it is not delivered, the recipient’s system typically sends back some sort of notification as to why. A “hard” bounce is when you receive a notification that the non-delivery is due to a permanent condition, such as the intended recipient is no longer at the company. A “soft” bounce is when the notification indicates the non-delivery was due to a temporary condition, such as a full mailbox or an “out of office” situation.
