Frequently Asked Questions about CASL

Yes, under the "Implied Consent" B2B exemption, provided the contact publicly published their email, did not state they refuse unsolicited mail, and your message is directly relevant to their business role.

Detailed Technical Breakdown

Unlike the opt-out model of the US CAN-SPAM Act, CASL operates primarily on an opt-in basis. For B2B outbound, senders can leverage "Implied Consent" only if the contact's business email was conspicuously published without a statement declining unsolicited messages and the email directly relates to the recipient's business role.

The Canadian Radio-television and Telecommunications Commission (CRTC) strictly investigates non-compliant commercial email operations.

CASL mandates that every message contain clear identification of the sender, postal contact details, and an operational unsubscribe mechanism functioning for at least 60 days.

Why it matters for Cold Email & Deliverability

CASL is one of the most strictly enforced anti-spam laws globally, featuring corporate fines of up to $10 million CAD for non-compliance.

Canadian email providers and enterprise firewalls aggressively block non-compliant outbound sending networks.
