In the reports from your newsletter sendings you can see how many email messages that have bounced. A bounced email is an email that for some reason could not be delivered to the recipient.
Bounces can be divided into different categories:
Hard bounces - A hard bounce is typically due to the e-mail address not being valid. The e-mail address might be misspelled or non-existing or the email account might also have been closed.
Soft bounces - A soft bounce means that the e-mail address does exist, though the recipient's inbox might be full and can therefore not receive any e-mails.
Technical bounces - This type of bounce might be due to a temporary problem at the recipients e-mail server. The server might not have been available at the time of the sending, it might be temporarily down, overloaded etc.
Other bounces - We do not have any information for this type of bounce, due to the fact that the recipient’s server has not sent back any information to our sending servers.
Please note that emails that have been stopped by spam filters do not always result as bounced messages.
