SMS and WhatsApp notifications

Send reminders, confirmations and alerts to Canadian customers by SMS and WhatsApp, from the 4notify dashboard or through its API. Replies to SMS can be read and a STOP reply unsubscribes the contact. For commercial messages, Canada's Anti-Spam Legislation (CASL) requires consent, sender identification and a working unsubscribe mechanism — 4notify sends the messages, while collecting and documenting consent remains your responsibility.

Frequently asked questions

Does 4notify make me CASL-compliant?

No tool does that on its own. CASL compliance depends on how you obtain and record consent and what you send. 4notify handles delivery and STOP opt-outs for SMS; keep your consent evidence in your own records.

Are transactional messages exempt from CASL consent?

Certain messages — for example confirming a transaction or delivering a requested service — are exempt from the consent requirement, but identification rules still apply. Check with your advisor for your specific case.

Can I integrate it into my application?

Yes. 4notify exposes an API for SMS and WhatsApp, authenticated with client credentials.
