To keep our clients safe, we have several anti-spam programs running. One of them tracks the number of bounced emails. If that number in unreasonable excess of normal rates the account is flagged and you will be notified. It's a good idea to review your mail.s content and to cleanse the recipients. database. The most common reasons for emails to be bounced back are:

• the recipient address is wrong
• the recipient is not personally identified in the email
• the recipient has not verifiably and explicitly granted permission for the message to be sent. Please review our notes on the CAN-SPAM Act
