A bounce is an email whose delivery was rejected by the recipient email server.
Recipients cause hard bounces when their e-mail addresses are no longer valid. The receiving server then sends an automatic message to our server, which the system reads and interprets.
In contrast, soft bounces occur when e-mails are rejected, mostly due to a temporary failure. This can happen, for example, if the recipient’s mailbox is crowded or if the receiving server is temporarily unavailable.
- You can view and edit all bounces in your customer account.
- In the main menu click on Recipient and then select the Bounce Management tab.
- Bounces are not automatically removed from mailing lists. We therefore recommend manually deleting recipients with at least one hard bounce from the mailing list.
- However, if a recipient’s address causes two hard bounces, the system automatically refrains from sending a newsletter again for the next 60 days. You will receive a message in the system.
