What does 'SOI' mean as a Payable Action?

Every offer on WOW Trk for affiliates show a 'Payable Action' the payable action simply informs you what a user must do when visiting the affiliate offer in order for you to be paid.

If the 'Payable Action' states SOI (Single Opt In), this means the user must sign up but they do not need to verify their email address in order for you to earn commission.

If the 'Payable Action' stated DOI instead of SOI, then the user would need to sign up and verify their email address in order for you to earn commission.
