Opt-in

Opt-in is the prior, freely given and explicit consent of a person to receive commercial messages.

Definition

Opt-in is the prior, freely given and explicit consent of a person to receive commercial messages.

In detail

Opt-in is the agreement given upfront by the person concerned. It must be freely given, specific, informed and unambiguous: a pre-ticked box or consent buried in terms and conditions does not qualify.

In France, commercial SMS prospecting towards individuals rests on this principle: without prior, demonstrable consent, the send is unlawful. The burden of proving consent lies with the sender.
