Many writers are now using email lists. It’s a great way to spread the word about your work, simply because you get into the inbox of your fans. However, there are legal requirements involved with using an email list. In the US, you have CAN-SPAM. In Canada, you have CASL. In Australia, you have the Spam Act of 2003. You are subject to the laws in your home country, hence, you need to ensure that you know exactly what your legal requirements are.
But don’t panic. You don’t need to be able to read legalese. There are many out there who have made it easy for you. Personally, I like the infographic from Bettina Specht. It breaks down all the sticky bits of the law into the different countries, including fines and what information MUST be disclosed in each email. Take a look at it. You might be in for a bit of a surprise.
