What’s a bounce?

Sort elements

• The reason for non-delivery is due to a permanent error that signals the contact or email domain is unknown or doesn’t exist. A hard bounce can also mean a spam block. When you first send to your mailing list immediate bounces, such as a non-existent email address, are recorded and the contact is immediately set to ‘Bounced’, as there’s no point trying to send to these contacts.
• A temporary error that signals a full mailbox, temporarily unavailable domain or receiving server issues.
• Generally related to company policy where staff are not allowed to receive messages with certain wording, images or attachments. The receiving server is likely to block this type of mail.
