Anti-spam compliance in email marketing

When you engage in email marketing, bulk mailing or send email campaigns there are some legal issues that you should be aware of.

Some basics you should know

The following points are indicative and it is your responsibility to be properly informed about the applicable laws in your country (and not only).
  • The full and valid physical postal address of the sender must be included in every email message.
  • The subject line must describe the nature and the content of the email.
  • Subject lines must not be deceptive.
  • The "from" line should display the business name or the sender's name and it should not be a marketing buzzword.
  • A reply address that will be active for at least 30 days after sending the email must clearly exist.
  • An unsubscribe link must be included in every email.
  • Unsubscribe requests must be validated within 30 days.

  • If you received an email that appears to be coming from kindly inform us. It is not from us. This is called spoofing where the sender of the email changes the <From-email> and <From-name> fields in order to hide his identity and use someone else s. Usually, by checking the Internet headers of such an email you can see the IP address of the sender, his real email and mail servers he used. Most of the times these will point to servers in countries where law enforcement, especially when it comes to the Internet, is practically non-existent.
