Definition
A solo ad is a one-offer email send purchased from a list owner. Buyers typically pay per click or per delivery to a landing page they control, often used for list building and affiliate offers.
Buying basics
Request recent proof, clarify unique vs raw clicks, start with a test order, and use a dedicated tracking URL per seller.
ROI lens
Judge solo ads by cost per confirmed subscriber and downstream revenue — not by vanity open rates you cannot verify.
