What are the reasons listed under the Spam section of the preflight report?

The system uses the newest version of SpamAssassin to check your campaigns for spam characteristics prior to each send. If you choose to run the Spam preflight report, or if your organization has set it up to run as a default, the purpose of this feature is to inform you of the likelihood that your message will be categorized as spam by various Internet Service Providers (ISPs). A summary of any findings are provided in the Preflight Report dialog box under the Spam heading.

• BODY: HTML has a low ratio of text to image area means that the campaign has heavy image content. You should consider adding more text to balance the campaign.
• The "Multipart message mostly text/html MIME" finding refers to the proportion of the HTML version to the plain text version (content on plain text tab compared to content in Page 1).
• The "raw illegal characters" finding is usually referring to characters such as &, <, >, \, /, # that may have been included in the content of your campaign.
• The "one time rip off" finding refers to the text "one time" or "rip off" or some combination thereof within the campaign content.

Generally a score of less than 5 will prevent your message from being classified as spam. We recommend adjusting those elements that you can minimize, such as limiting the use of "free", dollar signs, all capital letters, etc.
