OPT-IN
Definition
The act by which the respondent and/or panelist consents to inclusion by agreeing to be considered for membership in a respondent community or panel. All messages sent to invite participation in survey research should be permission-based or "opt-in", i.e. the recipient should have taken action to sign up or grant permission to receive market research survey invitations. In a “double opt-in” system, the respondent and/or panelist consents to inclusion by first agreeing to be considered for membership, and then confirming that agreement at a later point (such as validating contact information and/or email address). ACE strongly recommends a double opt-in registration process.
