The double opt-in is basically an improved version of the SOI. To comply with anti-spam guidelines and to regulate the number of fake registrations, DOI, which means Double-Opt-In, was developed. This means that an additional step is required to be able to confirm the registration of the user. This is checked by a simple confirmation email that is linked with a confirmation link. As soon as the user has verified his registration with it, the double opt-in process is completed.
