Outdated email addresses, full mailboxes or technical problems on the recipient’s side lead to a certain number of delivery problems with every mailing. If these are not detected and cleaned up, they have a long-term negative impact on the deliverability of the entire domain. It is just as important to know who has unsubscribed from a mailing, so that these recipients are no longer contacted in future. 1Tool shows both pieces of information directly for every campaign.",[14,15,17],"h2",{"id":16},"looking-at-hard-bounces-and-soft-bounces-separately","Looking at hard bounces and soft bounces separately",[10,19,20],{},"Not every delivery problem should be assessed in the same way. A hard bounce means that an address is permanently undeliverable, for example because it no longer exists. A soft bounce, on the other hand, indicates a temporary problem, such as a full mailbox or a short-term server outage on the recipient’s side. 1Tool shows both categories separately for every newsletter campaign, so you don’t just see a lump-sum bounce figure but can tell whether the problem is permanent or temporary.
