Frequently asked questions

How does CASL consent tracking work?

Every message recipient has an associated consent record (express or implied) with date, source, message type. Express consent requires double opt-in. Audit log immutable for 3-year evidence retention per CASL §13.

Are transactional messages exempt from CASL?

Yes — transactional messages (delivery confirmations, password resets, receipts) and certain B2B messages are exempt. The system classifies messages and applies the correct rules.

Do you handle bilingual unsubscribe pages?

Yes — unsubscribe pages render in the recipient's preferred language (EN or FR Quebec) with proper sender identification, mailing address and effective immediately processing.

What about Quebec privacy law?

Quebec Law 25 affects how personal information is collected and processed. Marketing notifications respect both CASL (anti-spam) and Law 25 (privacy) — explicit consent + purpose disclosure required.
