It's unlikely you will know if your email is undelivered, even more unlikely is that you would know when it is flagged as SPAM and why. To determine whether an e-mail is spam most spam filters examine a number of different rules: such as content, length, percentage of text, use of images, number of recipients, headers, sender. They will then formulate a spam score for every e-mail which passes through the server.
Some common rules are 3 or more capitalized words in the Subject line, no subject text, subject starts with Hello or Free or GUARANTEED etc , subject line starts with Buy or Buying, email has more than 70 percent blank lines. The above is an ever growing list and as spam senders become more wily the rules are likely to become more stringent.
