Definition of Opt’in
Opt-in is prior consent to the sending of advertisements. In France, it is not forbidden to send advertising within the framework of the recipient’s professional activity. Conversely, it is not permitted to send unsolicited advertising e-mails to private individuals without their prior consent. Even if the sender respects opt-in, he or she must still respect opt-out.
Opt-in is to be contrasted with opt-out.
Applications
As opt-in e-mail advertising is accepted in France, ALTOSPAM does not consider this type of e-mail as spam.
