<b>SOI vs DOI: what the second email really does</b>

<b>SOI vs DOI: what the second email really does</b>

New to sweeps? Start here. Both terms describe how an offer counts a lead.

SOI = Single Opt-In. The person types their email, presses submit, and you get paid. One step.

DOI = Double Opt-In. The person types their email, then must open a confirmation email and click a link inside. Two steps.

Why the second step matters: it filters out fake or careless emails. On a DOI offer you might lose 40-60% of submits between the form and the confirm click. That gap is normal and expected.

Tiny example. Say 100 people fill your form.
— On SOI at $1.50 each, all 100 count. You earn $150.
— On DOI at $4.00 each, maybe 45 confirm. You earn $180.

Same traffic, different math. DOI pays more per lead because the advertiser trusts it more. SOI pays less but converts more of your clicks.

Neither is better. They suit different traffic. Cheap, cold traffic often dies on the confirm step, so SOI is kinder to it. Warmer, more engaged traffic survives DOI and earns more.

Next step: open any offer you are considering and find the word SOI or DOI in its description. Write it down before you spend a cent.
