If you've checked unsubscribe on an unsolicited email before, then you know the feeling. 

Businesses that don't adhere to Canada's anti-spam legislation (CASL), have to pay up and pay up big. We're talking in the millions, so companies need to be diligent and comply with legislation to avoid being heavily fined. There is a checklist to follow so that people don't check you off theirs. 

What's more? Canadian's may be nice, but they aren't too nice to sue. In 2015, a Google poll found 54 percent of Canadians considered joining class-action lawsuits against companies for anti-spam violations. 

So before you go sending mass emails, think about your customer base, and better yet think twice about coughing up, because as of July 1, 2017, the transitional period ends and the scope of what emails are allowed becomes more restrictive.
