The main difference between opt-in and opt-out is how a system treats customers or users and the type of input that is required from them. A subscription system is one in which a person needs to actively indicate an interest or desire to be a part of something. In contrast, an opt-out agreement makes users part of a system and gives them the opportunity to opt out of it. Technology-wise, the way initial communication is handled in the opt-in and opt-out methods is different, with more options in sight for the former.

One of the main differences between an opt-in and opt-out system is how a user initially interacts with each of them. A subscription agreement is one where someone has to actively select whether they want to be a part of a newsletter or other opportunity. This requires some foresight on the part of developers or programmers making this type of choice, as the choice must be clear to the user.
An optional system is usually designed to be accessible and provide as much information as possible. Using a subscription method requires developing an interface that clearly presents the option. Contact information must be provided by someone interested in the information through this system and can simply be added to a list of opt-in records.
While the two systems are means by which information can be distributed to other people, the way people become part of them is quite different. In an opt-out agreement, someone is automatically qualified as a contact and is registered through another system. This can occur through the sale of contact details, although it is often used as a means of ongoing communication after a sale or other service.
From a technological point of view, an opt-out system can be quite easy to create. The data is used from another source to complete a list of people who are part of this service. It is up to users to indicate that they no longer wish to be part of a mailing list or other program. You must provide them with some method to opt out of the settlement. This can be a bit tricky, but usually involves a link or other simple flag that sends a warning to remove someone’s information from a list.
Generally, it is best for a service to use a method that is a combination of a subscription and opt-out agreement. Initial terms of contact may be established through subscription features, with additional opt-out opportunities at a later time. When someone wants to unsubscribe, options can be provided to continue receiving information while removing unwanted features. A combination of opt-in and opt-out features may require the use of multiple tables and lists to maintain multiple opportunities. However, doing so allows people to control the frequency or scale of future communication.
