DOI (Double Opt-In)

Veranika Minina 27 February 2024

DOI (Double Opt-In) is a type of offer according to which a conversion is counted when users provide their email and/or personal data, and then confirms their email address.

DOI offers are popular in affiliate marketing because they help ensure the quality of leads and reduce the risk of fake or invalid email addresses being used. Let’s discover other peculiarities of DOI offers.

DOI Meaning

DOI offers, resemble SOI offers but with an extra layer of verification. They require a confirmation step, which can take various forms such as emails, text messages, or even voice calls, depending on the specific offer. Typically, users provide their contact details and are promptly validated through a code sent via text or email, or through a phone call. Once this confirmation process is successfully finalized, the conversion is counted.

As there are additional funnel’s step, DOI offers often have lower conversion rates, but higher payouts compared to SOI. Single Opt-In converts well, but the quality of leads is lower as well as payouts. However, despite the lower conversion rates, running offers with longer registration and confirmation processes can lead to more engaged and interested leads.

DOI: How does it Work?

Generally, the process involves the following steps:

  • User’s Initial Action: Consumers take an initial action, such as filling out a form, providing their email address, or signing up for a newsletter;
  • Email Confirmation: As a rule, a confirmation email is sent to users provided email addresses. The email typically contains a link or a button that the user needs to click to confirm their subscription or consent;
  • Double Confirmation: By clicking the confirmation link or button, users confirm their interest or agreement to receive emails or offers from an affiliate.

By promoting DOI offers, affiliate marketers may earn commissions for each user who completes an action and becomes a confirmed lead. The commission structure and payout terms depend on the advertisers’ requirements.
