Defining Email Blocks, Bounces, and Drops While in Enquire MAP

A block to an email is when the email server that the User is sending the email to is refused. There are many reasons for this:

• Addressee might decide the email is Spam
• Identify the email as a violation to an internal policy 
• Addressee may no longer exist on the mail server

A bounced email is an email that will be sent back because of some error. Bounces can be categorized as:

• 
  Soft-bounces are 4xx error level and are often temporary, and will reach the recipients email server then be sent back due to a full destination inbox, a server error, or an email address that no longer exists
• 
  Hard-bounces are 5xx error level and are permanent failures; hard bounces will be sent back because of an invalid address

A drop is if it has already bounced, or if it is invalid. These occur to help protect sender reputation.
