Opt
A term used to describe a user's acceptance or participation of a program. For example, a user who chooses to opt-in to an e-mail newsletter will start receiving that newsletter until they choose to opt-out. Many e-mail solicitations that are sent out by companies enable users to opt-out from receiving similar e-mails in the future by replying to the e-mail with remove or by visiting a page to unsubscribe.
- Additional information about opting in and out from the Computer Hope newsletter can be found on the Computer Hope newsletter page.
