Anti-spam test

Brief description

This test examines the content and the subject of the mailing for content that may exhibit spam characteristics. The more suspicious content is found, the more probable it is that the mailing will be moved to the spam folder.

Possible test results

This categorisation is based on the evaluation of the spam characteristics of the widely distributed spam filter, ‘SpamAssassin’. The overall test rating is calculated from the total number of individual spam features:

• green = 0
• orange = 0.1 to 3.0
• red = over 3.1

A result categorised as ‘green’ means that your mailing has no spam characteristics and can be sent without hesitation.

If the result is categorised as ‘orange’ or ‘red’, you should resolve the causes. Do not send mailings that have been categorised as ‘red’.

In addition to the colour coding of the test result, a description of the result is provided and, if necessary, specific instructions on how to act. The instructions tell you how to prevent your mailing from being classified as spam.

In addition, comply with the following tips in the mailing text and in the subject line to eliminate spam characteristics:

• Always specify a full sender address (real name).
• Do not use the domains ‘.biz’ and ‘.dotinfo’.
• Do not create mailings that consist almost entirely of images. The text part of a mailing should always be larger than the image section.
• Avoid using a font that is too small or too big.
• Avoid using sentences in all caps.
• Avoid exclamation marks, dollar and euro signs.
• Avoid having too little contrast between the font and the background colour.
• Avoid using words that exhibit spam characteristics (your family, your job, ...)
