Collect WhatsApp consent

← Back to Klaviyo + WhatsApp Documentation

Learn how you can collect consent to send WhatsApp messages, including what methods are available and best practices for doing so.

Types of WhatsApp messages and consent

WhatsApp classifies their messages into 4 categories.

Type of message	Available in Klaviyo?	Requires explicit consent?
Promotional (called “marketing” in Klaviyo)	Yes	Yes
Utility (called “transactional” in Klaviyo)	Yes, but only via imports. Collecting transactional consent is coming soon.	Yes
Support	No, but it’s coming soon.	N/A
Authentication	No

In most cases, you need explicit consent to send a WhatsApp message, meaning that someone must directly tell you that they wanted to receive certain messages from your brand.

Currently, Klaviyo supports importing both marketing and transactional consent for WhatsApp, and you can collect marketing consent via forms. However, it’s on our roadmap to add Support consent as well as the ability to collect WhatsApp transactional consent in forms.

Best practices when collecting WhatsApp consent

Never assume that you have someone’s consent already.
- If someone consents to another channel (e.g., signing up for SMS) or provides their phone number, this isn’t the same as agreeing to receive WhatsApp messages.
Include clear disclosure language wherever you collect consent for WhatsApp.
- This includes on forms, your website, emails, etc.
Verify the phone number before sending (i.e., use double opt-in to confirm the number is real and belongs to the person who signed up).
