Before you start

Be a manager on the Callizy account.
Know what the law asks of you. Callizy gives no legal advice: for Canada’s Anti-Spam Legislation (CASL), check with the CRTC.

Step by step

5 steps, about 4 min

1
Note each customer’s consent
1 min
Callizy has no consent box on contacts. Note yourself how the customer gave their consent, for example in a note on their record: see Contacts, notes and tasks after a call.
2
Text one customer at a time
10 s
Callizy has no bulk texting. Each text goes to one person, from their conversation.
3
Sign your automatic texts
2 min
Callizy adds neither your business name nor “Reply STOP”. Write them yourself in your automatic texts: the Send a text block of a flow, the AI agent’s SMS Actions and a reference table’s text.
4
When a customer replies STOP
10 s
Texts from that number no longer reach them. If you text them, Callizy shows “This recipient has unsubscribed from your messages.” and the text doesn’t go out.
5
Toll-free and the United States
1 min
A toll-free number must be enabled for texting. A local number that texts the United States must be registered in the Trust center, which asks How your customers give consent. See Texts to the United States and from a toll-free number.

Key points

Callizy doesn’t check consent: get it before you text.
Callizy adds nothing to your texts: your business name and the opt-out are yours to write.
A customer who replies STOP no longer gets texts from that number.

Settings

You can change them at any time, without reconnecting anything.

Texts sent on your behalf: The Send a text block of a flow. The AI agent’s SMS Actions. A reference table’s text. An appointment confirmation, per the Confirmation method. The fallback text of an AI call campaign. Reread each one.
The page for your customers: The Text message consent page explains when a business using Callizy may text, and how to unsubscribe.

Not working?

Callizy shows “This recipient has unsubscribed from your messages.”

The customer replied STOP to a text from this number.
Reach them another way, by phone for example.

Callizy shows “This number can’t receive text messages.”

It is often a landline: call it instead.

Callizy shows “Text not sent”

To a US number: register your number in the Trust center. See Texts to the United States and from a toll-free number.

Frequently asked questions

Does Callizy make my texts CASL-compliant?

No. Callizy sends your texts. Consent, identification and the opt-out remain your responsibility, as the Terms and Conditions of Sale and the Acceptable Use Policy say. For the law, check with the CRTC.

Can I text my whole list at once?

No. Callizy has no bulk texting. Automated sends, through the API, Claude, ChatGPT or Zapier, are limited to 20 texts per minute.

Where can I see who unsubscribed?

Callizy doesn’t keep that list. The refusal shows when you text.
