Opt-in and opt-out

A person's recorded consent to receive messages, and their request to stop.

Consent rules (GDPR, CASL, TCPA, India's DPDP Act, WhatsApp's policies) require permission for many business messages. Good practice: store the source, time and wording of each consent, and honour STOP-style opt-outs instantly across every channel.
