A bounce event will be recorded by Prospect.io when an email message cannot be delivered. Emails can bounce for various reasons. Depending upon whether or not this bounce is expected to be permanent, we speak of a hard or soft bounce.
A hard bounce can happen, for instance, when the email address is invalid. The hard bounce is « permanent ».
A hard bounce will automatically stop the campaign for the bounced prospect. You can also choose to automatically archive the prospect when an email message hard bounces.
A soft bounce occurs when the recipient's mailbox is full or the mail server is temporarily unavailable.
