SOI (Single Opt-In)

Veranika Minina 27 February 2024

In affiliate marketing, SOI is a type of offers that means that affiliates get commissions when users leave contact information without verification. As a rule, this info includes contacts: email or phone number.

SOI Meaning

SOI (Single Opt-in) is an offer where users only need to perform a single action, such as submitting an email address or completing a simple form, to become a lead or subscriber. And users don’t need to confirm their email additionally.

SOI offers are generally associated with lower payouts compared to other types of offers in the affiliate marketing, regardless of the GEO. Despite smaller payouts it’s easier to receive conversion. As a result, SOI offers are often recommended as a starting point for marketers who are new to the field.

SOI: How does it Work?

In a Single Opt-In process, users typically provide their email address or other relevant information on a landing page or signup form. Once they submit the form, users are immediately added to the desired platform without requiring any further confirmation or verification.

Single Opt-In processes are often used in situations where simplicity and ease of conversion are prioritized. However, it’s important to note that SOI can raise the risk of fake emails as there is no additional verification step. Additionally, it may lead to a higher likelihood of users inadvertently subscribing without intending to do so, potentially leading to lower engagement rates or a higher rate of spam complaints.
