Opt-in
A user's explicit permission to receive marketing or transactional messages from a business on a given channel.
Definition
Opt-in is the act of a contact giving clear, recorded consent to receive messages from a business — by checking a box on a form, replying with a keyword, scanning a QR code, or accepting at checkout. Channels like email (GDPR, CAN-SPAM), SMS (TCPA in the U.S.), and WhatsApp all require some form of opt-in, and platforms expect businesses to be able to prove when and how consent was captured. Without it, deliverability suffers and legal risk rises.
Example
A visitor downloads a lead magnet and checks a box that says "Send me product updates by email and WhatsApp." That timestamped record is the opt-in proof for both channels.
