When collecting consent through an online form, the checkbox agreeing to receive marketing messages should be checked by default.

The statement is false because consent for marketing messages, especially SMS, must be explicit and freely given. Pre-checked boxes, often referred to as "opt-out" mechanisms, are generally not considered valid consent under privacy regulations like GDPR, CCPA, and TCPA. Users must actively choose to opt-in by manually checking the box, demonstrating their clear intention to receive communications. This ensures compliance with legal requirements and builds trust with your audience. If the box were pre-checked, it would imply consent without an active decision from the user, which is not compliant.
