Warning

This post is intended to illustrate the complexity of laws are around sending commercial email messages. It is not intended to be used as a check-box for campaign compliance. I do not practice law so please do not take anything in this post as legal advice.

Bulk email falls into one of two categories: commercial and non-commercial. Non-commercial messages are often referred to a transactional or service messages because they relate directly to a service that the sender is providing. Examples of transactional messages include invoices and password-reset notifications. Commercial messages are everything else including special offers, promotional content, and lead/demand generation activities.

Many countries have laws related to the sending of commercial email. This post will focus on four significant markets: the United States, Canada, Europe, and the United Kingdom.

The table below compares the core requirements for sending commercial email in these markets.

There can be significant complexity around complying with sending commercial email regulations. For example:

  • You may be required to comply with legislation from two jurisdictions depending on where you and the recipient are located.
  • Unsubscribe links in the EU/EEA and UK technically need to remain active indefinitely since they are indirectly covered by rights around objecting to data processing which never expire. In reality there are work-arounds.
  • While unsolicited or opt-out commercial messages are permitted in some jurisdictions, not all mailbox providers permit them - see the bulk sender guidelines post for more information.

The governing bodies (linked to in the table) are best place to start for more information on a particular piece of legislation. I have also included some additional resources below. I would strongly suggest you seek legal counsel before sending bulk commercial messages and especially if you intend to send unsolicited ones as that’s normally where the tears start and fines begin.
