Can I email them? A CASL checker

Canada's Anti-Spam Legislation (CASL) decides who you can send sales emails to. Answer a few questions about one person and see whether you have consent, how long it lasts, and what the email itself must include.

Is the person in Canada, or are you sending from Canada?

How did you get their email address?

They opted in (ticked a box, signed up, or said yes to emails)They bought from me or had a contract with meThey asked me about my products or servicesTheir business address is published (on their website or a directory)They gave me their address themselves (business card, conversation)Someone who knows us both referred me to themI bought or rented a list, or found it some other way

Every commercial email also needs

Your name and your business's name (and who you're sending for, if it's someone else)
Your mailing address, plus a phone number, email or website
A working unsubscribe link or reply option in every email
Unsubscribes honoured within 10 business days, and the option working for 60 days after sending
A subject line and sender that aren't misleading

General information about CASL, not legal advice. For a specific situation, talk to a lawyer.

The short version of CASL

You need consent to send a commercial email to or from Canada. Express consent (they said yes) lasts until they unsubscribe. Implied consent comes from a purchase (2 years), an inquiry (6 months), or a business address someone published or gave you, as long as your message fits their role. Every email must say who you are, give a mailing address, and offer a working unsubscribe.
