CASL
Canada's Anti-Spam Legislation. It sets clear rules for how you collect consent and send marketing emails to people in Canada.
CASL is Canada's main law for commercial email. It covers any marketing or promotional message sent to someone in Canada. The law focuses on consent, identity, and unsubscribe options. If you email Canadian subscribers, CASL applies even if your business is based in another country.
CASL matters because fines can be large and regulators do act on complaints. It pushes you to get clear permission before you email anyone. You must be able to prove when and how someone joined your list, and every email needs simple unsubscribe and accurate sender details. When you follow CASL, you usually end up with a healthier, more engaged list.
A simple approach is to treat Canadian contacts as strict opt in only. Use clear signup forms, send a short confirmation email, and log consent in your CRM or email tool. Review older contacts on a schedule and clean out people who never confirmed or stopped engaging. This keeps you safer under CASL and improves deliverability at the same time.
