However, if not properly constructed, it can be flagged by spam filters as an unwanted message. So how do you create an e-mail signature that is effective and safe at the same time?


Why might e-mail signatures be marked as spam by spam filters?


Spam filters use a number of algorithms that analyze various elements of e-mail signatures, including the footer. Factors that can make filters suspicious include:

  • Large amounts of bold, underlined or colored text: Such elements can be seen as an attempt to attract attention in an aggressive manner.
  • Repeated keywords: Excessive use of the same keywords may suggest that the message is spammy.
  • Unclear or misleading information: If the e-mail signature information is vague or misleads the recipient, it can raise suspicion.
